A comprehensive investigation of hadal basalts from the southern Mariana Trench (SMT) conducted with microscopic examinations shows that iddingsite occurs as augite-hosted veins, rims, and mineral grains formed completely in place of augite within the SMT basalts. Carbon geochemistry indicates that organic matter with homogenous <i>δ</i>¹³C values between –27.8‰ and –27.2‰ might be biogenically accumulated in the SMT basalts. Furthermore, the close spatial relationships between carbonaceous matter (CM) and goethite in iddingsite point to microbial attachment to iddingsite minerals. Thus, iddingsitization might have fueled H₂-utilizing microorganisms inhabiting the hadal oceanic crust, thereby leading to the formation of CM, as implied by oxygen isotopic compositions revealing low alteration temperatures (32–83°C) favorable for microbial growth.

The Middle Jurassic Xishanyao Formation, located in the southern Junggar Basin of northwestern China, has geological conditions with rich CBM resources. The 46 Xishanyao coal samples gathered from the drilling cores and coal mines cover 4 types of macrolithotypes (bright coal 1, semi-bright coal 2, semi-dull coal 3, and dull coal 4) and 2 types of coal structures (primary coal I and cataclastic coal II). Based on a range of pore testing experiments and analytical methods, the dual effects of different macrolithotypes and coal structures on pore structures were intensely studied. The results showed that the specific surface area (SSA) and total pore volume (TPV) of coal samples increased gradually from bright to dull coals. For the same macrolithotypes, the SSA and TPV of the primary coals were lower than those of the cataclastic coals. Generally, the pore structures of bright and semi-bright coals are simpler when compared to semi-dull and dull coals with the same coal structure, whereas cataclastic coals have more complicated pore structure systems than primary coals with the same macrolithotypes. The bright and semi-bright coals have higher vitrinite contents and more endogenous fractures, whereas well-developed structural fractures were identified in cataclastic coals. Therefore, bright and semi-bright coals have better pore connectivity than semi-dull and dull coals with the same coal structure, the pore connectivity of cataclastic coals being slightly better than that of primary coals under the same macrolithotypes. In terms of the CBM adsorption conditions, the eight type samples formed a descending order: II-4 &gt; I-4 &gt; II-3 &gt; I-3 &gt; II-2 &gt; I-2 &gt; II-1 &gt; I-1, while they ranked as follows when consideration was given to the CBM seepage capacities: II-2 &gt; II-1 &gt; I-2 &gt; I-1 &gt; I-3 &gt; I-4 &gt; II-3 &gt; II-4. As a result, it could be determined that the bright and semi-bright coals had stronger adsorption capacities, whereas the cataclastic coals had better pore connectivity and seepage capacities. Pore structure characteristics should be analysed under the dual control of different macrolithotypes and coal structures, so that they can provide greater value for guiding CBM exploration and exploitation, as along for preventing underground gas accidents.</p>","PeriodicalId":7095,"journal":{"name":"Acta Geologica Sinica ‐ English Edition","volume":"99 1","pages":"194-211"},"PeriodicalIF":3.5,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analysis included multivariate statistical techniques, such as correlation analysis, R-mode cluster analysis, Q–Q plots and factor analysis. Subsequently, we decomposed the geochemical anomalies, identifying weak anomalies using spectrum-area modeling and local singularity analysis.

In comparison to conventional methods, spectrum-area modeling and local singularity analysis outperform in terms of identification of anomalies. Ultimately, we considered four specific target areas (AP01, AP02, AP03 and AP04) for future exploration, based on geochemical anomalies and favorable geological factors. Within AP01 and AP02, the geochemical anomalies suggest potential mineralization at depth, whereas in AP03 and AP04 the surface anomalies require additional geological investigation.

Based on the integration of core, well logs, and three-dimensional seismic data, this study presents a comprehensive analysis of the Permian carbonate platform and strike-slip faults in the southwestern Kaijiang-Liangping trough of the Sichuan Basin. The relationship between strike-slip faults and Permian carbonate microfacies is investigated. The results reveals the existence of a NW-trending strike-slip fault zone along the platform margin, exhibiting clear segmentation. The western side of the study area exhibits a rimmed platform margin characterized by type I reefs, which corresponds to the presence of a large-scale strike-slip fault zone. In contrast, the eastern side is characterized by a no-rimmed and weak rimmed platform margin, accompanied by type II reefs, which align with smaller strike-slip fault zones. It was found that the strike-slip fault had some effects on the platform and reef-shoal complex of the Permain Changxing Formation. First, the platform was divided by strike-slip fault into three segments to show rimmed, week rimmed and no-rimmed platform. Second, reef-shoal complex devolped along the faulted high position in the strike-slip fault zone, and separated by faulted depression. Third, strike-slip faults can offset or migrated the reef-shoal complex and platform margin. Additionally, the thickness of the platform margin varies across strike-slip fault zone, which is related to the activity of strike-slip faults. The strike-slip faults affect the microfacies by controlling the pre-depositional paleotopography.

Our study employs zircon Lu-Hf and bulk rock Sr-Nd isotopes, along with mineral geochemistry, to track the melt sources of the Nymo intrusive complex and the role of mantle magma during the early Eocene flare-up of the Gangdese arc, Tibet. The Nymo intrusive complex is composed of gabbronorite, diorite, quartz diorite, and granodiorite which define an arc-related calc-alkaline suite.

It is demonstrated that during the stage I, regional compression is introduced by early stages of plate convergence, causing the folding and thrusting and creating structural or lithological traps such as evaporite diapirs and unconformity-related carbonate dissolution-collapse structures. Thereafter, in stage II, hydrocarbons begin to migrate and accumulate within these traps, where reduced sulfur is generated through thermochemical or bacterial sulfate reduction concurrent with or preceding Zn-Pb mineralization. In the subsequent stage III, as plate convergence persists, the regional stress transitions from compression to transpression or extension. Under these conditions, steeply-dipping extensional faults are generated, facilitating the ascent of metalliferous brines into early-formed structural or lithological traps.
