By comparing the pore structures of shales at various burial depths, we investigate the evolution of pore systems during tectonic uplift. The results indicate that micropores and mesopores hosted in organic matter dominate the shallow Longmaxi Formation shale, contributing nearly all adsorption gas storage space and a large portion of free gas capacity. Although mesopores exhibit more complex surface morphologies and spatial configurations than micropores, micropores display stronger heterogeneity. Organic matter exerts a primary control on pore development, while carbonate and clay minerals influence meso- and macropore structures. During tectonic uplift, favourable preservation conditions persist, and a dynamic balance between pore fluid escape and the rate of overburden erosion ensures that pore structure and morphology remain essentially unaffected.

Four compositionally different zones are identified in some of the altered chromite grains; though optically they are distinguished into two such as: dull grey and white reflective. The reflectivity is related to a marked enrichment of FeO and NiO and depletion of Cr₂O₃, MgO, and Al₂O₃, resulting in the formation of spinelloid composition that lies between the end-members of FeCr₂O₄ (chrome-magnetite) and Fe₃O₄ (magnetite). Chromite replacement by ferritchromit/chrome-magnetite/magnetite usually takes place from grain boundaries or micro-cracks and fractures inwards giving rise to altered grains consisting of mostly relict chromite cores enveloped by thin ferritchromit and variably thick chrome-magnetite/magnetite rind. Progressive increase in Cr# and drastic decrease in Mg# from grey core to white reflective mantle suggests post-formation fracturing. The ferritchromit and its associated spinel phases in the Sukinda ultramafic rocks are attributed to elemental exchange and its variable precipitation during serpentinisation and represent alteration products formed through progressive, fluid-driven recrystallisation during regional tectonothermal events below 500°C.</p>\u0000 </div>","PeriodicalId":12784,"journal":{"name":"Geological Journal","volume":"61 7","pages":"1943-1962"},"PeriodicalIF":2.6,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148532838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between alteration and mineralization is of considerable significance for the exploration of deep and surrounding ore deposits. This study elucidates the alteration and mineralization characteristics of the deposit through comprehensive geological mapping of alterations, logging of drill holes and short-wave infrared (SWIR) spectroscopy. Detailed geological mapping of surface alterations indicates that intense silicification and hornfels alteration are predominantly located within the central mining area, which is proximal to the location of deep ore bodies. The spatial distribution of chlorite alteration closely aligns with the locations of the ore bodies, thereby serving as an effective indicator of ore body occurrence. Results from drill hole logging and SWIR analysis reveal that skarn alteration minerals, such as diopside, garnet, phlogopite and actinolite, are directly associated with copper-polymetallic mineralization, while chlorite alteration is consistently observed across the drill holes. In terms of SWIR spectral characteristics, the Fe-OH characteristic absorption peak (Pos2250) of chlorite associated with porphyry-type alteration diminishes from the No. VII copper-polymetallic ore body towards the periphery. This trend effectively reflects the distance from the hydrothermal mineralization centre: chlorite located near the ore body is relatively Fe-rich, whereas that situated further away is comparatively Mg-rich. Notably, the Pos2250 value of chlorite within the skarn alteration does not exhibit a distinct spatial pattern. Although the Al-OH characteristic absorption peak (Pos2200) of montmorillonite–muscovite group minerals also decreases outward from the ore body, its interpretative significance is limited in this deposit due to the inherent differential alteration zoning characteristic of skarn-type deposits. Consequently, elevated Pos2250 values of chlorite (&gt; 2250.0 nm) within porphyry-type alteration, in conjunction with the presence of abundant skarn mineral assemblages, are identified as effective exploration indicators for the mineralization centre of the Mamupu deposit. For future exploration in the southern YPCB, we advocate for a comprehensive research approach that integrates geology, spectroscopy and genetic analysis: delineating alteration zones through geological mapping, targeting mineralization centres using spectral parameters and interpreting genetic models through comparative geological analysis. This methodology is anticipated to facilitate advancements in the exploration of deep and peripheral regions.</p>\u0000 </div>","PeriodicalId":12784,"journal":{"name":"Geological Journal","volume":"61 7","pages":"2087-2105"},"PeriodicalIF":2.6,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The No. 8 coal seam of the Benxi Formation, situated on the deep eastern margin of the Ordos Basin in the Daning–Jixian Block, serves as the research subject. Multiple regression analysis was employed to model the relationships between logging parameters and Langmuir volume, Langmuir pressure, porosity and water saturation.

Four machine learning methods—BP neural network, multiple linear regression, random forest and support vector machine—were utilised to construct a total gas content evaluation model. Errors of the machine learning models were evaluated, and the random forest model was identified as the optimal choice. A comparison between predicted gas content and measured pressure coring results indicates that both the logging and RF models are efficient, accurate and effective.

In this study, 10 influencing factors of soil erosion are identified. The causative factors for soil erosion are elevation, aspect, plan curvature, profile curvature, annual average rainfall, drainage density, slope, geology, distance from the lineament and land use. These factors are further divided into sub-factors, and their relative contribution to soil erosion is modelled using the analytic hierarchy process (AHP). The causative factors are reclassified in the GIS environment, and the weightages calculated using AHP are assigned. The reclassed parameters are overlaid to get an erosion susceptibility map, which is divided into five categories according to the erosion susceptibility index, from very low to very high. It is found that the erosion susceptibility index of the study area varies from 0.016 to 0.423. It is observed that 38% of the total study area is under high and very high erosion susceptibility zones. Around 15% of the study area faces very high erosion susceptibility.

By integrating lithology, thickness, and density data from drillings and outcrops into a 3D ArcGIS model, we analysed sediment flux to resolve debates about the basin's tectonic history. Results reveal distinct spatial distributions between the upper and lower segments of the Qiongzhusi Formation: (1) The spatial distribution of clastic materials in the lower segment of the Qiongzhusi Formation was primarily controlled by the geomorphic constraints of the extensional trough, (2) The sedimentary center of the upper Qiongzhusi Formation shifted northwestward, exhibiting a distinct northwest-thickening and southeast-thinning trend. This spatial reorganisation reflects a fundamental change in basin dynamics: the lower segment's sedimentation was controlled by the geomorphic constraints of a weakly extensional trough, while the upper segment's asymmetric thickness and elevated sediment flux along the northwestern margin (linked to crustal shortening) signal the onset of weak compression.
