Teixeira et al. (2025) integrated previously published regional geophysical and geochronological data with new gravimetric surveys of the Dom Feliciano Belt (DFB) and surrounding areas. However, the paper contains a few inaccuracies and overlooks some publications that should be considered in a review. This comment aims to deepen the discussion by recognizing some data not considered in their paper, foccusing in a critical evaluation of (1) "terrenology" as a working philosophy in the context of DFB, considering (2) the authochtonous nature of major tectonic domains, (3) the non-continuity between Dorsal de Canguçu and Major Gercino shear zones, and (4) the controversial origin of hinterland batholiths either as post-collisional or magmatic arc.
Teixeira等人(2025)将先前发表的区域地球物理和地质年代学数据与Dom Feliciano带(DFB)及周边地区的新重力测量数据相结合。然而,这篇论文包含了一些不准确的地方,并且忽略了一些应该在评论中考虑的出版物。这篇评论的目的是通过承认他们的论文中没有考虑到的一些数据来深化讨论,重点是对以下几个方面进行批判性评估:(1)“气源学”作为DFB背景下的工作哲学,考虑(2)主要构造域的权威性,(3)Dorsal de canguu和major Gercino剪切带之间的不连续性,以及(4)腹地岩基的有争议的起源,无论是碰撞后的还是岩浆弧。

Impact of organic-inorganic interactions on shale source-reservoir systems 有机-无机相互作用对页岩源储体系的影响

Organic-inorganic interactions are ubiquitous within organic-rich shale systems and exert a pivotal control on the formation and evolution of integrated shale source-reservoir systems. However, a comprehensive and in-depth understanding of the microscale physicochemical processes underpinning these interactions in shale source-reservoir systems remains lacking to date. This review provides a holistic elaboration of the evolutionary processes of shale source-reservoir systems and systematically synthesizes the diverse pathways of organic-inorganic interactions in organic-rich shales. At the macroscale, climatic conditions and provenance jointly constrain the mineral composition during sedimentation. At the microscale, minerals exhibit selective adsorption characteristics toward organic matter (OM) owing to differences in adsorption mechanisms, which directly modulates the abundance and type of OM in sediments. The physical protection afforded by mineral pores mitigates the oxidation of organic carbon and regulates the overall reactivity and burial efficiency of organic carbon. During the thermal evolution stage, minerals and transition metals significantly accelerate kerogen cracking by reducing reaction activation energy, providing proton donors, or facilitating free radical reactions. Notably, under high-temperature conditions, inorganic-derived hydrogen and oxygen drive extensive organic-inorganic interactions, which exert a profound impact on deep hydrocarbon generation potential, natural gas isotopic compositions, and the upper limit of secondary pore formation. The generation of organic acids fuels pore evolution in shale reservoirs; secondary pores formed via mineral dissolution alter the pore characteristics and heterogeneity of shales. Ions released during dissolution drive mineral transformation and authigenic mineral precipitation. Coupled with the involvement of exogenous hydrogen, the sustained acid generation from hydrocarbon pyrolysis in deep reservoirs perpetuates this pore-forming effect. During the mature to high-maturity stages, organic-inorganic interactions exert a prominent influence on pore formation and heterogeneity. Even at higher thermal maturity levels, these interactions persist due to the participation of inorganic hydrogen and oxygen, yet the depth threshold of organic-inorganic interactions remains undefined. The formation of integrated shale source-reservoir systems is a complex, dynamic evolutionary process involving the coupling of multiple components, stages, and mechanisms. Focusing on the regulatory mechanisms of organic-inorganic interactions in integrated shale source-reservoir systems, this review synthesizes key scientific issues including mineral - and transition metal compound-catalyzed hydrocarbon generation, hydrocarbon evolution involving multi-source hydrogen, and pore development under varying maturity conditions. It aims to provide theoretical support and scientific guidance for the exploration and
有机-无机相互作用在富有机质页岩体系中普遍存在,对页岩整体生储体系的形成和演化起着关键的控制作用。然而,迄今为止,对支撑页岩源储系统相互作用的微观物理化学过程的全面而深入的理解仍然缺乏。本文从整体上阐述了页岩源储体系演化过程,系统地综合了富有机质页岩中有机-无机相互作用的多种途径。在宏观尺度上,气候条件和物源共同制约了沉积过程中的矿物组成。在微观尺度上,由于吸附机制的差异,矿物对有机质表现出选择性吸附特征,这直接调节了沉积物中有机质的丰度和类型。矿物孔隙提供的物理保护减轻了有机碳的氧化,调节了有机碳的整体反应性和埋藏效率。在热演化阶段,矿物和过渡金属通过降低反应活化能、提供质子供体或促进自由基反应显著加速干酪根裂解。值得注意的是,在高温条件下,无机衍生氢和氧驱动广泛的有机-无机相互作用,对深层生烃潜力、天然气同位素组成和次生孔隙形成上限产生深远影响。有机酸的生成促进了页岩储层孔隙演化;矿物溶蚀作用形成的次生孔隙改变了页岩孔隙特征和非均质性。溶解过程中释放的离子驱动矿物转化和自生矿物沉淀。再加上外源氢的参与,深层储层中烃类热解产生的持续酸使这种成孔效应得以延续。在成熟至高成熟阶段,有机-无机相互作用对孔隙形成和非均质性影响显著。即使在较高的热成熟度水平,由于无机氢和氧的参与,这些相互作用仍然存在,但有机-无机相互作用的深度阈值仍然不确定。页岩源储一体化系统的形成是一个复杂的动态演化过程,涉及多个组分、阶段和机制的耦合。本文围绕页岩源储一体化体系中有机-无机相互作用的调控机制,综合了矿物和过渡金属化合物催化生烃、多源氢烃演化、不同成熟度条件下孔隙发育等关键科学问题。旨在为非常规油气资源的勘探开发提供理论支持和科学指导。

Previous studies have constrained fault slip rates and crustal block geometries of the Southeastern Tibetan Plateau (SETP) with contradictory results due to complex geodynamics and deformation patterns as well as subjective choices of crustal block boundaries. In this work, we address the issue of uncertain crustal block geometries by employing an unsupervised machine learning Euler pole clustering algorithm that automatically resolves regions that behave as rigid blocks (clusters) rotating on a sphere using GNSS velocity vectors. Optimal clustering results, determined by F-test and Euler-vector (angular velocity vector) overlap analyses, indicate 4 elongated crustal blocks exist in the SETP that are approximately parallel and delineated by a set of arcuate sinistral-slip faults. Our clustering results redefine the first-order kinematics of the SETP region with new crustal block definitions that elucidate the dominance of sinistral-slip faults.
由于复杂的地球动力学和变形模式以及对地壳块体边界的主观选择,以往的研究对青藏高原东南部的断层滑动率和地壳块体几何形状进行了约束,但结果相互矛盾。在这项工作中,我们通过采用无监督机器学习欧拉极点聚类算法来解决不确定地壳块几何形状的问题,该算法使用GNSS速度矢量自动解析在球体上旋转的刚性块(簇)区域。通过f检验和欧拉矢量(角速度矢量)重叠分析确定的最优聚类结果表明,SETP中存在4个细长的地壳块体,它们近似平行,由一组弧形的正弦滑动断层所描绘。我们的聚类结果用新的地壳块体定义重新定义了SETP区域的一阶运动学,阐明了左滑断层的主导地位。

Soil frost heave seriously threatens the stability of engineering structures and the normal operation of major infrastructures in cold regions. This paper aims to synthesize the development and state of the art in moisture migration, cryostructure, soil frost heave, as well as their underlying micro-mechanisms, impacting factors and simulation models. First, we provide a brief review on moisture migration, cryostructure and soil frost heave. Second, some microstructural experiments incorporate X-ray computed tomography (X-CT), scanning electron microscope (SEM), and nuclear magnetic resonance (NMR) were reviewed to elucidate the underlying micro-mechanisms. Third, impacting factors for soil frost heave covering soil intrinsic properties, testing and environmental conditions were summarized. Moreover, numerous frost heave models involving theoretical, numerical, and machine learning (ML) models were discussed. Then, we point out some limits and identify the direction of future efforts. Despite advances achieved through decades of researches, some issues remain in the research on the frost heave of the coarse-grained soils, and soils with admixtures. To solve these problems by performing one-dimensional (1D) freezing and microstructural experiments on these soils considering these factors, and establishing novel frost heave models. Overall, this review will provide significant references for further research on soil frost heave, and an important theoretical guidance for the prevention and control of the frost heave distresses of infrastructures.
寒区土壤冻胀严重威胁着工程结构的稳定和重大基础设施的正常运行。本文旨在综合水分迁移、冻土结构、土壤冻胀及其微观机制、影响因素和模拟模型的研究进展和现状。本文首先对水分迁移、冻土结构和土壤冻胀的研究进展进行了综述。其次,对x射线计算机断层扫描(X-CT)、扫描电镜(SEM)和核磁共振(NMR)等显微结构实验进行了综述,以阐明其微观机制。第三,总结了影响土冻胀的因素,包括土的特性、试验和环境条件。此外,还讨论了许多涉及理论、数值和机器学习(ML)模型的冻胀模型。然后,我们指出了一些限制,并确定了未来努力的方向。尽管经过几十年的研究取得了一定的进展,但粗粒土和掺合料土的冻胀研究仍存在一些问题。为了解决这些问题,在考虑这些因素的基础上对这些土进行了一维冻结和微观结构试验,并建立了新的冻胀模型。综上所述,本文将为进一步开展土壤冻胀研究提供重要参考,并为基础设施冻胀灾害的防治提供重要理论指导。

A comprehensive scientific research roadmap is essential to bridge knowledge gaps and deepen the understanding of key geological, geochemical, and geophysical aspects of natural hydrogen (H<ce:inf loc="post">2</ce:inf>) as a potential new energy resource. This paper reviews major scientific uncertainties on natural H<ce:inf loc="post">2</ce:inf>, suggesting research priorities, as a guide for defining exploration strategies, techniques, and data interpretation. The uncertainties concern all phases of the natural H<ce:inf loc="post">2</ce:inf> cycle, from generation (source rocks) through migration (advection and diffusion) and accumulation (reservoir and cap rocks) to the application and interpretation of subsurface and surface geochemical and geophysical exploration techniques. Understanding H<ce:inf loc="post">2</ce:inf> sources and generation rates (the amount of H<ce:inf loc="post">2</ce:inf> generated by a given volume of rock over time) is crucial for determining whether a geological H<ce:inf loc="post">2</ce:inf> system operates as a short-term dynamic system with rapid H<ce:inf loc="post">2</ce:inf> production and release, or as a conventional gas system with long-term accumulations, analogous to petroleum reservoirs. Preliminary estimates for serpentinisation, radiolysis, and organic matter degradation suggest that H<ce:inf loc="post">2</ce:inf> generation is not inherently fast, especially for non-hydrothermal continental systems (crystalline basement of shields, ophiolites, peridotite massifs, sedimentary basins), and long-term accumulations, like those of fossil natural gas systems, represent the most likely scenario. The mechanisms of H<ce:inf loc="post">2</ce:inf> migration through geological formations require application of fundamental principles of fluid-flow physics, distinguishing advection and diffusion, as well as their forms (from gas-phase, bubble flows to aqueous solutions). Additional studies of H<ce:inf loc="post">2</ce:inf> accumulation and retention in subsurface reservoirs could improve understanding of mechanisms of H<ce:inf loc="post">2</ce:inf> migration by focusing on the rock fluid-bearing properties and the factors affecting H<ce:inf loc="post">2</ce:inf> preservation, such as the presence of cap rocks impermeable to H<ce:inf loc="post">2</ce:inf>, pressure conditions, residence times, and microbial or abiotic consumption.

全面的科学研究路线图对于弥合知识空白和加深对天然氢(H2)作为潜在新能源的关键地质、地球化学和地球物理方面的理解至关重要。本文回顾了天然氢气的主要科学不确定性,提出了研究重点,以指导勘探策略、技术和数据解释。这些不确定性涉及自然H2循环的所有阶段,从生成(烃源岩)到迁移(平流和扩散)和聚集(储层和盖层),再到地下和地表地球化学和地球物理勘探技术的应用和解释。了解氢气的来源和生成速率(给定体积的岩石随时间产生的氢气量)对于确定地质氢气系统是作为一个具有快速氢气生成和释放的短期动态系统运行,还是作为一个类似于油藏的具有长期聚集的常规气体系统运行至关重要。对蛇纹石化、辐射分解和有机物降解的初步估计表明,H2的生成本身并不快,特别是对于非热液大陆系统(盾状基底、蛇绿岩、橄榄岩地块、沉积盆地),而像化石天然气系统那样的长期积累是最有可能的情况。氢气在地质构造中的运移机制需要应用流体流动物理学的基本原理,区分平流和扩散,以及它们的形式(从气相、气泡流到水溶液)。对地下储层中氢气聚集和滞留的进一步研究可以通过关注岩石的含流体性质和影响氢气保存的因素(如不渗透的盖层、压力条件、停留时间、微生物或非生物消耗)来提高对氢气运移机制的理解。包括储层建模、流动模拟、含氢岩石的三维成像(micro-CT)以及岩石中封闭气体的提取和分析在内的先进技术,可以深入了解H2聚集的稳定性和潜在可采性。地表勘探技术的解释,包括天然气地球化学、地球物理和遥感,长期用于矿产和能源勘探,现在正适用于天然氢气研究,但在数据解释方面仍然存在挑战。区分地表附近由现代微生物过程或人工来源(如锤击或钻孔进行土壤-气体取样、钻入含水层和钻孔腐蚀)产生的氢气的地质脱气导致的氢气渗漏是勘探的重要步骤。土壤中H2的简单检测,即使是在亚圆形洼地或“仙女圈”这样的形态结构中,也不能粗略地解释为H2从深层来源自然渗透的信号。建议采用全面的地球化学方法,包括与H2相关的气体的同位素分析,以区分各种可能的H2起源。对井中H2的观测应该进行询问,以排除可能的人工产物,如腐蚀和钻头变质。由于岩石特定物理性质的非唯一性,建议综合使用多种地球物理方法,包括地震、重力、磁力和电磁测量,以减轻对地下H2系统(源和储层岩石,包括流体和气体储存)结构的解释歧义。

This paper reviews major scientific uncertainties on natural H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt;, suggesting research priorities, as a guide for defining exploration strategies, techniques, and data interpretation. The uncertainties concern all phases of the natural H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; cycle, from generation (source rocks) through migration (advection and diffusion) and accumulation (reservoir and cap rocks) to the application and interpretation of subsurface and surface geochemical and geophysical exploration techniques. Understanding H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; sources and generation rates (the amount of H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; generated by a given volume of rock over time) is crucial for determining whether a geological H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; system operates as a short-term dynamic system with rapid H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; production and release, or as a conventional gas system with long-term accumulations, analogous to petroleum reservoirs. Preliminary estimates for serpentinisation, radiolysis, and organic matter degradation suggest that H&lt;ce:inf loc=\"post\"&gt;2&lt;/ce:inf&gt; generation is not inherently fast, especially for non-hydrothermal continental systems (crystalline basement of shields, ophiolites, peridotite massifs, sedimentary basins), and long-term accumulations, like those of fossil natural gas systems, represent the most likely scenario.
