The Duobaoshan island arc contains early Paleozoic association of adakitic high-Mg andesite, Nb-enriched basalt, and porphyry Cu deposits, concurrently indicating the ridge subduction in the eastern Xing’an Massif. This study further understands the unique island arc setting through the mantle metasomatism, oxygen fugacity and crustal thickness based on the zircon U–Pb geochronologic and Hf isotopic data from the early Paleozoic igneous and sedimentary rocks, as well as the whole–rock geochemical and Sr–Nd–Hf isotopic data from the igneous rocks in the Duobaoshan region, Xing’an Massif. The early Paleozoic igneous rocks are typical arc–type with low (La/Yb)_N ratios (3.37–6.60), exhibiting highly depleted zircon Hf (ε_Hf(t) = +12.44∼+16.50) and whole–rock Sr–Nd–Hf isotopic data ((⁸⁷Sr/⁸⁶Sr)_i = 0.7036–0.7048; ε_Nd(t) = +4.76∼+8.17; ε_Hf(t) = +12.44∼+16.50), which were derived from the depleted mantle metasomatized mainly by slab fluid accompanied with the altered oceanic crust melt and pelagic sediment melt, and reflected the maturing process of the island arc. In addition, the Early Ordovician igneous rocks indicated the increase of mantle temperature and oxygen fugacity (ΔFMQ > 2) leading to the solubility of metallogenetic elements, and the thickening crust was also conducive to the mineralization. Then we further revealed the existence of a Precambrian basement of the Xing’an Massif based on the sedimentary rocks, the geochronology of which revealed the youngest ages of 504–478 Ma, yielding the age peaks at 771 Ma, ∼860 Ma, ∼950 Ma, and ∼1800 Ma ∼2500 Ma. In the meanwhile, the Hf isotopic data of 600–478 Ma detrital zircons show depleted to more enriched ε_Hf(t) values (–10.22 to +12.70) and a proximal depositional traits, indicating that majority of the Neoproterozoic and early Paleozoic detrital zircons migrated from the Duobaoshan region, Xing’an Massif.

多宝山岛弧发育早古生代艾达质高镁安山岩、富铌玄武岩和斑岩型铜矿组合，同时显示了兴安地块东部的脊状俯冲。本研究基于兴安地块多宝山地区早古生代火成岩和沉积岩的锆石U-Pb年代学和Hf同位素数据，以及火成岩的全岩地球化学和Sr-Nd-Hf同位素数据，通过地幔交代作用、氧逸度和地壳厚度进一步了解独特的岛弧背景。早古生代火成岩为典型的弧型，低（La/Yb）N比值（3.37 ~ 6.60），锆石Hf高度贫化（εHf(t) = +12.44 ~ +16.50），全岩Sr-Nd-Hf同位素数据(（87Sr/86Sr） = 0.7036 ~ 0.7043；εNd (t) = + 5.71∼+ 8.17;εHf(t) = +12.44 ~ +16.50)，主要来源于以板块流体为主的衰竭地幔交代作用，并伴有蚀变的洋壳熔体和上层沉积物熔体，反映了岛弧的成熟过程。此外，早奥陶世火成岩表明地幔温度和氧逸度升高（ΔFMQ > 2），导致成矿元素溶解度增大，地壳增厚也有利于成矿作用。根据沉积岩进一步揭示了兴安地块前寒武纪基底的存在，其最年轻年龄为504 ~ 478 Ma，年龄峰值为771 Ma、864 Ma、942 Ma、~ 1800 Ma和~ 2500 Ma。同时，600 ~ 478 Ma碎屑锆石Hf同位素数据显示εHf(t)值（-10.22 ~ +12.70）为贫至富，具有近端沉积特征，表明新元古代和早古生代碎屑锆石主要来自兴安地块多宝山地区。

Over the past 60 million years, Earth has transitioned from a warmhouse to an icehouse climate. Understanding the variations in Earth-Moon orbital parameters during this interval is essential for understanding past tidal dissipation and predicting the future dynamical evolution of the Earth-Moon system. However, geological records that constrain the Earth-Moon system throughout the Cenozoic remain limited. Here, we analyzed high-resolution borehole gamma-ray logs from two wells (F154 and L242) in the Bohai Bay Basin (BBB), dated to approximately 41.25 Ma and 39.23 Ma, respectively. Using two independent astronomical methods, we reconstructed key orbital parameters, including the precession constant k, Earth-Moon distance (EMD) and length of day (LOD). The results showed that the precession constant k is 51.32 ± 0.22 arcsec/yr for well L242 and 51.33 ± 0.27 arcsec/yr for well F154. These geological k values are consistent with the Farhat model, correspond to the upper uncertainty range of the Waltham model, and significantly deviate from the Laskar model. Linear regression of the compiled geological k values indicates a long-term LOD increase rate of 1.39 ms/century over the past 60 million years. This rate is lower than the 2.13 ms/century predicted by Farhat model, likely due to enhanced hydrological and oceanic mass redistribution under extreme warming events in the early to middle Eocene. These findings provide new constraints on Cenozoic Earth-Moon dynamics and long-term variations in LOD throughout geological history.

在过去的6000万年里，地球从温室气候转变为冰窖气候。了解地月轨道参数在这段时间内的变化，对于理解过去的潮汐耗散和预测地月系统未来的动力学演化是至关重要的。然而，限制整个新生代地月系统的地质记录仍然有限。在这里，我们分析了渤海湾盆地（BBB）的两口井（F154和L242）的高分辨率井眼伽马射线测井曲线，分别约为41.25 Ma和39.23 Ma。利用两种独立的天文方法，我们重建了关键的轨道参数，包括岁差常数k、地月距离（EMD）和日长（LOD）。结果表明，L242井进动常数k为51.32±0.22 arcsec/yr， F154井进动常数k为51.33±0.27 arcsec/yr。这些地质k值与Farhat模型一致，对应于Waltham模型的上不确定范围，与Laskar模型偏差较大。对地质k值的线性回归表明，在过去6000万年中，LOD的长期增长速率为1.39 ms/世纪。这一速率低于Farhat模型预测的2.13 ms/世纪，可能是由于始新世早期至中期极端变暖事件下的水文和海洋质量再分配增强。这些发现为研究新生代地月动力学和LOD在地质历史上的长期变化提供了新的约束。

We present new geochemical data including whole-rock major and trace element analyses and Sr– Nd–Pb isotopic ratios for volcanic rocks from the northern part of the extensive Okhotsk–Chukotka Volcanic Belt (OCVB), a Cretaceous (ca. 106–71? Ma) subduction-related igneous province in NE Asia. Integration of previously published and new data revelas a clear along-arc zonation within the northern OCVB and demonstrates a correlation between magma isotopic composition and the age of the continental basement beneath the belt. A first-order distinction is observed between the Anadyr segment of the OCVB, underlain by relatively young and mafic continental crust (initial ⁸⁷Sr/⁸⁶Sr of 0.7032 to 0.7048, εNd of –1.3 to + 7.3, and ²⁰⁶Pb/²⁰⁴Pb of 18.17 to 18.51), and the Central Chukotka and East Chukotka segments superimposed on the Chukotka continent where the crust has been forming since at least the Neoproterozoic (initial ⁸⁷Sr/⁸⁶Sr of 0.7042 to 0.8685, εNd of –5.5 to + 2.5, and ²⁰⁶Pb/²⁰⁴Pb of 18.42 to 18.85). We suggest that the mafic magmas of the northern OCVB are largely derived from subcontinental lithospheric mantle domains that preserve distinct isotopic characteristics within each major terrane. The only significant temporal change in the elemental and isotopic composition occurred during the final magmatic stage at ca. 76–73 Ma, when declining heat flow led to reduced magma output rate, the extinction of crustal magma chambers, and possibly the deepening of mantle magma reservoirs.

Insect flight represents a key evolutionary innovation, yet the impact of mass extinctions on wing evolution remains unclear. We reconstruct wing shape evolution in Permopsocida (Carboniferous–Cretaceous) based on morphometric approaches. The present study reveals a tri-phasic pattern: pre-extinction expansion, end-Permian bottleneck and post-extinction redirection. Despite opportunities in the Mesozoic, structurally conservative features constrained aerodynamic innovation. During the Jurassic-Cretaceous period, wings elongated convergently as compensatory adaptations, not as functional breakthroughs. Morphological disparity recovery lagged behind and was decoupled from early angiosperm radiation but synchronized with gymnosperm diversity. These findings demonstrate how extinction-induced structural constraints redirected evolution through compensatory adaptation.

昆虫飞行代表了一项关键的进化创新，但大灭绝对翅膀进化的影响尚不清楚。基于形态计量学方法重建了石炭纪-白垩纪Permopsocida翼形演化。本研究揭示了灭绝前扩张-二叠纪末瓶颈-灭绝后重定向的三阶段格局。尽管中生代有机会，但结构保守的特征限制了空气动力学的创新。在侏罗纪-白垩纪时期，翅膀逐渐拉长是一种补偿性适应，而不是功能上的突破。形态差异恢复滞后于早期被子植物辐射，与裸子植物多样性同步。这些发现证明了灭绝引起的结构约束如何通过补偿性适应重新引导进化。

The Nazca Ridge subduction beneath the Peruvian forearc presents a unique setting to evaluate the interplay between buoyant ridge subduction and continental forearc deformation. The current understanding of forearc deformation is largely based on numerical models with limited, field-based input data from small areas. This paper therefore presents a reconstruction of tectonic deformation in this region based on two topographic profiles across the entire continental forearc. The forearc overlying the ridge crest and leading edge hosts the large Quaternary Nazca Peneplain (QNP), which has registered uplift and deformation since the onset of ridge subduction. We developed a Conditional Variational Autoencoder (CVAE) deep learning model to reconstruct the QNP to its pre-eroded state and used this surface as input for two retrodeformed topographic profiles. The QNP and adjacent marine terraces were then dated using cosmogenic nuclide exposure and luminescence methods and used to calculate deformation rates. Forearc deformation involves uplift primarily due to folding, with basal thrusting or buoyancy of the Nazca Ridge acting as secondary drivers. Shortening rates since 1.85 ± 0.18 Ma to the present range from 0.32 to 0.36 mm a^-1, and surface uplift rates up to 0.37 mm a^-1. The 1.85 ± 0.18 Ma age combined with a regional bounding surface between shallow marine and fluvial gravels, provides an estimate for the timing of Nazca Ridge-overriding plate coupling. These results align with, and refine, previous numerical predictions on forearc deformation due to buoyant ridge subduction and offer a high-resolution dataset for future studies.

秘鲁前弧下的纳斯卡脊俯冲为评价浮力脊俯冲与大陆前弧变形之间的相互作用提供了一个独特的背景。目前对弧前变形的理解主要是基于数值模型和有限的、基于小区域的现场输入数据。因此，本文基于横跨整个大陆前弧的两条地形剖面，对该地区的构造变形进行了重建。上覆脊顶和前缘的前弧发育大面积的第四纪纳斯卡准平原（QNP），自脊俯冲开始以来，纳斯卡准平原发生了隆升和变形。我们开发了一个条件变分自编码器（CVAE）深度学习模型来重建QNP到其预侵蚀状态，并使用该表面作为两个反向变形地形剖面的输入。然后使用宇宙核素暴露和发光方法确定了QNP和邻近的海洋阶地的年代，并用于计算变形率。弧前变形主要是由于褶皱引起的隆升，纳斯卡山脊的基底逆冲或浮力是次要驱动因素。从1.85±0.18 Ma到现在的缩短速率为0.32 ~ 0.36 mm a-1，地表抬升速率为0.37 mm a-1。1.85±0.18 Ma年龄结合浅海砾石和河流砾石之间的区域边界面，提供了纳斯卡山脊-上覆板块耦合的时间估计。这些结果与之前关于浮力脊俯冲引起的弧前变形的数值预测一致，并对其进行了改进，为未来的研究提供了高分辨率的数据集。

The late Paleozoic-Mesozoic geological record of Antarctica is preserved in sedimentary successions deposited in the Gondwanide retroarc foreland basin. This basin developed as a direct response to convergence and crustal thickening along the southern margin of Gondwana during subduction of the paleo-Pacific plate. This protracted convergent tectonic setting drove the evolution of the Transantarctic Basin, which persisted from the Devonian through the Jurassic. The Transantarctic Basin is primary filled up by continental deposits, now exposed along the Transantarctic Mountains from the Weddell Sea to the northern Victoria Land. These Devonian-Jurassic sedimentary successions exhibit variations in thickness, provenance, and sedimentary facies, reflecting the long-term evolution of the paleo-Pacific convergent margin. This study investigated the late Paleozoic-Mesozoic paleo-topographic evolution of the central Prince Albert Mountains, where a thin Gondwanan stratigraphic succession is exposed. We integrate low-temperature thermochronological data (apatite fission-track and zircon (U-Th)/He) with stratigraphic evidence. Modeled thermal histories reveal an exhumation episode during the late Carboniferous to Permian, associated with the growth and subsequent erosion of a previously undescribed topographic high, referred to as Prince Albert High. The Prince Albert High formed between northern and southern Victoria Land and evolved synchronously with the Devonian-Triassic deposition of the Beacon Supergroup. We interpret its formation as a response to far-field stresses transmitted from the paleo-Pacific convergent margin, providing new insights into the geodynamic history of the Transantarctic Basin. Subsequently, this topographic high was buried beneath a Mesozoic overburden. This burial left evidence of a medium-temperature (150–180 °C) reheating process recorded in the basement and cover rocks.

南极洲晚古生代-中生代的地质记录保存在冈瓦尼德弧后前陆盆地的沉积序列中。该盆地是古太平洋板块俯冲期间冈瓦纳南缘辐合和地壳增厚的直接反应。这种漫长的趋同构造环境推动了横贯南极盆地的演化，从泥盆纪一直持续到侏罗纪。横贯南极盆地主要由大陆沉积物填满，现在沿着横贯南极山脉从威德尔海到维多利亚地北部暴露出来。这些泥盆系—侏罗系沉积序列在厚度、物源、沉积相等方面表现出不同的特征，反映了古太平洋辐合边缘的长期演化过程。本研究考察了阿尔贝王子山脉中部晚古生代-中生代古地形演化，暴露出薄的冈瓦南地层演替。我们将低温热年代学数据（磷灰石裂变径迹和锆石(U-Th)/He）与地层证据相结合。模拟的热历史揭示了石炭世晚期到二叠纪期间的一次挖掘事件，与先前描述的地形高地（称为阿尔伯特王子高地）的生长和随后的侵蚀有关。阿尔伯特王子高地形成于维多利亚地南北之间，与灯塔超群的泥盆纪-三叠纪沉积同步演化。我们将其形成解释为对古太平洋辐合边缘传递的远场应力的响应，为跨南极盆地的地球动力学历史提供了新的见解。随后，这一地形高地被埋在中生代覆盖层之下。这种埋藏在基底和盖层岩石中留下了中温（150-180°C）再加热过程的证据。

The financial sector stands at a critical crossroads in the 21st century, wielding immense power to shape our world’s economic landscape and environmental future. The role of finance in climate change is increasingly scrutinized as the world grapples with environmental degradation. Once a cornerstone of economic growth, financial development faces a paradox: how can it drive prosperity while enhancing environmental quality? While previous research has extensively explored the economic implications of financial development, its potential to improve environmental quality through mechanisms like energy transition and eco-innovation remains relatively unexplored. This study explores the interplay between financial development, energy transition, and eco-innovation in shaping the environmental quality in EU nations. Advanced econometric techniques, including the panel quantile regression and Artificial Neural Network (ANN) methods, are utilized to achieve this objective. The results reveal that while financial development significantly increases the ecological footprint, energy transition and eco-innovation contribute to its reduction. Interestingly, the interaction between financial development and energy transition negatively impacts the ecological footprint, suggesting that financial development can indirectly improve environmental quality when aligned with energy transition efforts. Similarly, the interaction between financial development and eco-innovation exhibits a negative effect, although its significance varies across different quantiles. The results remain consistent after the robustness check. These findings have important implications for EU policymakers seeking to achieve sustainable development goals, particularly in balancing financial sector growth with environmental protection. The study suggests implementing differential regulatory frameworks for financial institutions. Specifically, it proposes imposing stricter credit regulations on environmentally polluting industries while creating more favorable lending conditions for sustainable energy investments and eco-innovative enterprises. These policies will likely align financial sector development with sustainable development.

21世纪，金融业正站在一个关键的十字路口，拥有塑造世界经济格局和环境未来的巨大力量。随着世界与环境恶化作斗争，金融在气候变化中的作用受到越来越多的审视。金融发展曾经是经济增长的基石，但它面临着一个悖论：如何在促进繁荣的同时提高环境质量？虽然以前的研究已经广泛探讨了金融发展的经济影响，但其通过能源转型和生态创新等机制改善环境质量的潜力仍然相对未被探索。本研究探讨了金融发展、能源转型和生态创新在塑造欧盟国家环境质量中的相互作用。先进的计量经济学技术，包括面板分位数回归和人工神经网络（ANN）方法，被用来实现这一目标。结果表明，金融发展显著增加了生态足迹，而能源转型和生态创新则有助于减少生态足迹。有趣的是，金融发展和能源转型之间的相互作用对生态足迹产生了负面影响，这表明金融发展与能源转型努力相结合可以间接改善环境质量。同样，金融发展与生态创新之间的相互作用也表现出负向效应，尽管其显著性在不同的分位数上有所不同。稳健性检验后，结果保持一致。这些发现对寻求实现可持续发展目标的欧盟政策制定者具有重要意义，特别是在平衡金融部门增长与环境保护方面。该研究建议对金融机构实施差异化监管框架。具体而言，它建议对环境污染行业实施更严格的信贷监管，同时为可持续能源投资和生态创新企业创造更有利的贷款条件。这些政策可能会使金融部门的发展与可持续发展保持一致。
