The transition towards a sustainable energy system is critical in mitigating climate change and reducing the environmental impact of energy production and consumption. Technological innovation is pivotal in enabling this transition, offering solutions that can enhance energy efficiency, harness renewable sources, and minimize emissions. This study employed a dataset of 29 countries from 1995 to 2022 to investigate how technological innovation and renewable energy consumption influence environmental pollution. The study further classified the countries as energy importers and exporters to account for heterogeneity. To address potential endogeneity concerns, the study utilized the system-generalized method of moments (sys-GMM) as the primary estimator, with the Driscoll-Kraay estimator complementing a robust test. From the main European panel, technological innovation and renewable energy consumption significantly enhance the quality of the environment. Additionally, the interaction effect between technological innovation and trade openness improves the quality of the environment. Likewise, among energy importers and exporters in Europe, technological innovation and renewable energy consumption significantly enhance the quality of the environment. This study presents intriguing findings that warrant the attention of policymakers, as it sheds light on notable benefits of technical innovation and contributes considerably to the ongoing debate around energy transition and environmental sustainability.

Coupled detrital zircon U-Pb, Hf isotopic data from the Paleoproterozoic Belcher Group, Nunavut, Canada, are presented to determine maximum depositional ages and sedimentary provenance. We use these data to evaluate potential sediment sources with matching ages and εHf values within a paleogeographic context, to better define the configuration of microcontinents, terranes, and cratons surrounding the Belcher basin during its deposition. The distribution of detrital zircon spectra show that the lower Belcher Group was deposited on the passive margin of the Superior craton, whereas the upper Belcher Group (Omarolluk and Loaf formations) was deposited in syn-orogenic phase, broadly reflecting the opening and closing stages of the Manikewan Ocean, respectively. The lower Belcher Group data show dominant detrital zircon populations between 2825 and 2690 Ma (associated with negative εHf values) with only minor detrital input from sources < 2100 Ma. The dominant grain population is interpreted to be derived from the northeastern Superior craton (>2680 Ma grains), and the Winnipeg River and North Caribou terranes (<2680 Ma grains). The upper Belcher Group shows a dramatic shift in detrital ages from Archean to dominantly Paleoproterozoic, with dominant age peaks between ca. 1920 and 1900 Ma and only minor Archean input that includes 2500 Ma sources that are absent in the lower units. Archean populations document Sask craton-like ages and εHf values, whereas the dominant detrital 1920 to 1900 Ma age population shows positive εHf values that are consistent with being sourced from terranes located in the western Reindeer zone deposited in a submarine fan.
本文介绍了来自加拿大努纳武特地区古新生代贝尔彻群的锆英石U-Pb、Hf同位素耦合数据,以确定最大沉积年龄和沉积产地。我们利用这些数据来评估古地理背景下具有匹配年龄和εHf值的潜在沉积物来源,以更好地界定贝尔彻盆地沉积期间周围微大陆、陆相和陆块的构造。碎屑锆石光谱的分布显示,下贝尔彻组沉积于苏必利尔陨石坑的被动边缘,而上贝尔彻组(奥马罗鲁克地层和Loaf地层)则沉积于同步成因阶段,分别大致反映了马尼基万洋的开辟和关闭阶段。下贝尔彻群的数据显示,2825-2690Ma之间是主要的碎屑锆石群(与负的εHf值有关),只有少量碎屑从2100Ma以下的来源输入。据解释,主要谷物群来自苏必利尔陨石岩东北部(2680 Ma谷物)以及温尼伯河和北加勒比海陆相(2680 Ma谷物)。上贝尔彻群的碎屑年龄发生了戏剧性的转变,从阿新世为主转变为古近古生代为主,主要年龄峰值约在1920-1900Ma之间,只有少量的阿新世输入,其中包括2500Ma的来源,而这些来源在下部单元中是不存在的。Archean年龄群记录了Sask craton-like年龄和εHf值,而1920-1900Ma年龄群的主要碎屑岩则显示了正εHf值,这与来源于驯鹿区西部沉积在海底扇中的陆相矿床是一致的。

Spatiotemporal variations of Early to Middle Paleozoic magmatism in northern Beishan: Implications for accretionary and collisional processes in the southern Central Asian Orogenic belt

Spatiotemporal variations in magmatic compositions reflect changes in magma sources and their formation conditions, offering insights into geodynamic processes. This study presents new zircon U–Pb and geochemical data for early–mid Paleozoic granitoids in northern Beishan, located within the southern Central Asian Orogenic Belt. Late Ordovician (451 Ma) granodiorites are I-type and formed through water-fluxed melting of amphibolites. Early Devonian (403–397 Ma) granites show I-, S-, and A-type affinities with enriched Sr–Nd isotopes, indicating ancient crustal sources. Late Devonian to early Carboniferous (366–357 Ma) granitoids exhibit I-type characteristics. They and coeval intermediate-felsic intrusives show similar Sr–Nd–Hf isotopes, with 87Sr/86Sr(i) from 0.7045 to 0.7075, εNd(t) from −2.93–0.92, and zircon εHf(t) predominantly ranging from 2.9 to 6.5. Geochemical studies suggest their derivation from metasomatized mantle, with fractional crystallization playing a key role. Available data reveal three magmatic stages: ∼500–420 Ma, ∼420–390 Ma, and ∼ 370–350 Ma. Stage I mainly consists of (quartz) diorites, granodiorites, and granites. They show increasing K2O/Na2O and zircon saturation temperatures from south to north, with the Hanshan unit characterized by A-type granites. These variations reflect northward subduction of the Beishan Ocean, leading to water-fluxed crustal melting in the Mazongshan arc and dehydration melting in the Hanshan back-arc. In Stage II, complex mafic–felsic rock associations composed of (quartz) diorites, high-silica granites, gabbros, and intermediate–mafic volcanic rocks, along with high temperatures required for S- and A-type granite formation, suggest increased mantle heat input from slab breakoff following Beishan Ocean closure. Stage III rocks, confined to the Mazongshan unit, consist of diorites, tonalites, granodiorites, and granites associated with southward subduction of the Jijitaizi–Xiaohuangshan Ocean. This study demonstrates that multistage subduction–accretion contributed to Beishan orogen formation, highlighting magmatic compositional variations as key to understanding accretionary orogens.

Marine redox variations are widely accepted as an environmental driver for the Cambrian explosion, yet relative changes in shallow marine dissolved oxygen levels during the Ediacaran–Cambrian transition have long remained unconstrained. Here we present compiled nitrogen and organic carbon isotope data from shallow-water deposits in four sections, including new record from the Meishucun and Zhujiaqing sections, on the Yangtze Platform. The results reveal that nitrogenous environments with active denitrification prevailed in shallow ocean during the Terreneuvian, which may have been sufficient only for ecological successes of lophotrochozoans with relatively low O2 demands. In contrast, the diversification of ecdysozoans and deuterostomes with higher O2 demands was possibly suppressed and delayed until a rise of dissolved oxygen concentrations during the Cambrian Age 3. Our findings provide crucial support for a causal link between marine oxygen availability and rapid diversification of metazoans during the Cambrian explosion.

Xenoliths reveal East Gondwanan basement to Heard Island, Central Kerguelen Plateau

Increasingly it is recognised that the breakup of East Gondwana and formation of the Indian Ocean has led to the creation of many microcontinents, including Elan Bank, Gulden Draak Rise, and Batavia Rise. Whether the central and southern sections of the Kerguelen Plateau contain additional Gondwanan microcontinents remains controversial. Continental crust residing in these regions is mainly inferred from geochemical and geophysical datasets but little to no direct sampling evidence corroborates this. Here, we characterise continental rocks trawled from banks and plateaus on the Central Kerguelen Plateau, using petrographic techniques and U-Pb zircon and apatite dating. Recovered granitoids and felsic gneisses have Paleoarchean (∼3.3 Ga) and Mesoproterozoic (∼1.44 Ga, ∼1.19 Ga) zircon U-Pb crystallisation ages, as well as Mesoproterozoic (∼1.6 Ga, 1.15 Ga) and Cambrian (∼0.5 Ga) apatite U-Pb cooling ages. We interpret a microcontinent resides in the Central Kerguelen Plateau and must underly Heard Island, based on: (1) correlation of the U-Pb age groups of the recovered granitoid/gneissic rocks with conjugate Indian crust within East Gondwana, (2) regional geochemical and geophysical evidence for widely distributed microcontinental crust in the Kerguelen Plateau and (3) strong evidence supporting a local origin for the recovered rocks versus an ice-rafted Antarctic origin. Based on a volcanic rim preserved on a gneissic sample, we interpret portions of the Central Kerguelen Plateau microcontinent were entrained as xenoliths during the recent volcanic eruptions associated with Heard Island. A ridge jump of the Southeast Indian Ridge between 115–102 Ma likely formed the Central Kerguelen Plateau microcontinent and we speculate that related ridge jumps formed a near continuous ribbon of microcontinents along the Indian margin during the breakup of East Gondwana.
越来越多的人认识到,东冈瓦纳的解体和印度洋的形成导致了许多微大陆的形成,包括埃兰滩、古尔登-德拉克海隆和巴达维亚海隆。凯尔盖朗高原的中部和南部是否包含更多的冈瓦纳微大陆仍存在争议。这些地区的大陆地壳主要是通过地球化学和地球物理数据集推断出来的,但几乎没有直接的取样证据可以证实这一点。在此,我们利用岩石学技术以及铀-铅锆石和磷灰石测年法,描述了从凯尔盖朗中部高原的河滩和高原拖网中提取的大陆岩石的特征。回收的花岗岩和长英片麻岩具有古新世(∼3.3 Ga)和中元古代(∼1.44 Ga, ∼1.19 Ga)的锆石U-Pb结晶年龄,以及中元古代(∼1.6 Ga, 1.15 Ga)和寒武纪(∼0.5 Ga)的磷灰石U-Pb冷却年龄。我们解释说,凯尔盖朗高原中部有一个微型大陆,赫德岛的下面一定有一个微型大陆,其依据是:(1)回收的花岗岩/片麻岩的U-Pb年龄组与东冈瓦纳共轭印度地壳的相关性;(2)区域地球化学和地球物理证据表明凯尔盖朗高原广泛分布着微型大陆地壳;(3)强有力的证据支持回收的岩石起源于当地,而不是南极冰铸的起源。根据片麻岩样本上保存的火山边缘,我们解释了凯尔盖朗高原中部微大陆的部分岩石是在与赫德岛有关的近期火山喷发过程中夹带成异形岩的。印度东南海脊在115-102 Ma之间的一次海脊跃变可能形成了凯尔盖朗高原中部微大陆,我们推测在东冈瓦纳断裂期间,相关的海脊跃变沿着印度边缘形成了一条近乎连续的微大陆带。

Given the European Union’s initiatives to embrace cutting-edge technologies and transition to greener energy sources, it is imperative to assess the influence of climate technology and renewable energy utilization on the environmental sustainability of its member states. This study contributes to the existing body of literature by undertaking a novel assessment of the implications of climate technology and renewable energy consumption on load capacity factor, one of the most encompassing environmental sustainability indicators. To this end, the study examines data from 1990 to 2021 employing the “Continuously Updated Fully Modified” (Cup-FM) and “Continuously Updated and Bias-Corrected” (Cup-BC) approaches, concentrating on the five most attractive European Union countries for renewable energy: Germany, France, Spain, the Netherlands, and Denmark. The paper also considers the ecological impacts of economic growth, foreign direct investment, and urbanization. The results reveal a negative relationship between climate technology and ecological quality. While renewable energy consumption exhibits a positive but statistically insignificant association with ecological well-being, economic growth, foreign direct investment, and urbanization are found to have detrimental effects on ecological quality. In opposition to widely held claims, these striking observations suggest that renewable energy consumption and climate technology are not yet well equipped to fight the global climate battle. The underlying reasons behind these outcomes are thoroughly discussed, and strategies targeting Sustainable Development Goals 7 and 13 are proposed to catalyze advancements in research and development of cleaner energy and green technologies for a sustainable future.
考虑到欧盟采用尖端技术和向绿色能源过渡的举措,当务之急是评估气候技术和可再生能源利用对其成员国环境可持续性的影响。本研究对气候技术和可再生能源消费对负荷能力系数(最全面的环境可持续性指标之一)的影响进行了新颖的评估,为现有文献做出了贡献。为此,该研究采用 "持续更新完全修正"(Cup-FM)和 "持续更新和偏差修正"(Cup-BC)方法,对 1990 年至 2021 年的数据进行了研究,重点关注对可再生能源最具吸引力的五个欧盟国家:德国、法国、西班牙、荷兰和丹麦。论文还考虑了经济增长、外国直接投资和城市化对生态的影响。结果显示,气候技术与生态质量之间存在负相关关系。可再生能源消费与生态福祉之间呈现出正相关,但在统计上并不显著,而经济增长、外国直接投资和城市化则对生态质量产生了不利影响。与普遍的说法相反,这些惊人的观察结果表明,可再生能源消费和气候技术还不具备应对全球气候之战的能力。本报告深入探讨了这些结果背后的根本原因,并提出了针对可持续发展目标 7 和 13 的战略,以促进清洁能源和绿色技术的研究与开发,实现可持续发展的未来。

The underlying reasons behind these outcomes are thoroughly discussed, and strategies targeting Sustainable Development Goals 7 and 13 are proposed to catalyze advancements in research and development of cleaner energy and green technologies for a sustainable future.","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"22 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current era calls for an urgent need for environmental protection, and adaptation technologies stand as forerunners of innovations, putting transformative solutions to cope with the issues relating to the environment. Moreover, the imperative to adapt to frequently changing climate is at the heart of sustainable development goals. Understanding the dire need for adaptation technologies as an essential tool for building resilience and enhancing the load capacity factor to raise environmental quality, the present study focuses on the group of eight (G8) industrialized countries over the period from 1990 to 2020, to explore the role of adaptation technologies (ATEC) and green energy (REC) on the environmental quality (LCF). The empirical outcomes generated through Panel Quantile Regression (PQR) verify the existence of the LCC hypothesis in highly industrialized economies. The results show that ATEC positively and significantly affects LCF with an increasing rate from middle to upper quantiles. In contrast, REC has continuously an increasing impact throughout the quantiles with high significance. The robust outcomes are also endorsed by employing Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS). The study takes into consideration several Sustainable Development Goals (SDGs) like SDG 09 (adoption of technologies), SDG 07(green energy and renewable energy consumption), SDG 13 (climate action), SDG 14 (life below water), SDG 15 (life on land), SDG 03 (good health and well-being), SDG 06 (clean water and sanitation), SDG 11 (sustainable cities and communities), SDG 12 (responsible consumption and production), and SDG 17 (partnership for goals) while formulating policy implications, particularly for G8 economies.

Is energy security the missing piece of the environmental puzzle? Fresh evidence from load capacity factor and ecological footprint indicators

Despite their great potential, low-carbon energies can be used in limited amounts. Energy R&D expenditures can ensure that low-carbon energies are used at a rate close to their potential by increasing energy efficiency and reducing losses during the production and consumption phases. The positive environmental impacts of low-carbon energy and energy R&D expenditures can be accelerated by political globalization. As an example of political globalization, the Kyoto Protocol has enabled the adoption of clean technologies and low-carbon energies by providing various obligations to many countries, especially developed countries. Although some countries have withdrawn from the obligations embodied in the protocol, they are taking measures to ensure environmental sustainability through individual efforts in their own interests. The USA is the example that best reflects this. The environmental impact of energy security may vary depending on the energy sources that provide affordable and accessible energy. This study examines the effects of energy R&D expenditures, political globalization, energy security, and low-carbon energy consumption on the USA’s load capacity factor and ecological footprint from 1980 to 2018 using Fourier-based FMOLS and CCR estimators. The robust results of this study show that low-carbon energy consumption, energy technology R&D expenditures, and political globalization increase environmental sustainability. Policymakers should allocate more resources to developing low-carbon energy sources, increasing energy efficiency, and encouraging the adoption of clean energy technologies.
