Results of boreholes show that Permian strata is mainly composed of mudstone, sandy mudstone, siltstone, sandstone, sandy conglomerate, dolomite, and limestone. Detrital zircon U-Pb dating results of three sandstone samples yielded the calculated maximum ages of 296 Ma, 278 Ma and 293 Ma, indicating they possibly deposited during the Early Permian. Permian strata in the eastern Junggar Basin show similar rock associations and detrital zircon age data distribution patterns. Our new and compiled age data for sandstone samples in the eastern Junggar Basin and Bogda region yield predominant Paleozoic ages, close to their sedimentary ages. Such detrital zircon age data distribution patterns support the hypothesis that these Early Permian meta-clastic rocks in the eastern Junggar Basin and Bogda region were deposited in a subduction-related basin, and indicate an Early Permian Ocean prevented Precambrian detritus from the Central Tianshan block from depositing in the eastern Junggar Basin and Bogda region.</p>","PeriodicalId":7095,"journal":{"name":"Acta Geologica Sinica ‐ English Edition","volume":"98 6","pages":"1429-1440"},"PeriodicalIF":3.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252891","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}

However, our understanding of the formation mechanism and distribution of high-quality reservoirs in hyperpycnal deposits remains insufficient. In this study, the formation mechanism and distribution of high-quality reservoirs in the second member of the Sangonghe Formation are studied through sedimentology, petrology, and geochemistry, and 10 types of lithofacies were identified in the depositional sequences of the hyperpycnal flow. These can be summarized as gravelly bed to suspended load lithofacies association (GBS), gravelly reverse to normal compound-graded (GNR), coarse-grained sandy suspended load (CSS), and fine-grained sandy suspended load (FSS) lithofacies associations. The hyperpycnal system can be divided into four individual units: restricted channel, unrestricted channel, lobe, and levee. The reservoir quality varies with lithofacies. Gravelly bed load lithofacies has coarse grain sizes, high content of rigid minerals, and soluble components, such as magmatic rock fragments. Therefore, the gravelly bed load lithofacies reservoir has developed dissolution pores and well-preserved pore throats. Its reservoir quality is good. GBS and GNR are the main lithofacies associations in the restricted channel, where type I and type II reservoirs developed. The unrestricted channel is dominated by the CSS lithofacies association, with type III reservoirs developed. The lobe is dominated by the CSS and FSS lithofacies associations, with type III and type IV reservoirs developed. High-quality reservoirs mainly develop in the restricted and unrestricted channels, whereas reservoirs in the lobe have poor quality. The levees are dominated by siltstone and gray mudstone and are generally nonreservoirs.</p>","PeriodicalId":7095,"journal":{"name":"Acta Geologica Sinica ‐ English Edition","volume":"98 6","pages":"1533-1556"},"PeriodicalIF":3.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252813","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}

In this study, we integrate field observations, mineralogical and geochemical analyses, zircon U-Pb dating, and isotopic data to investigate the Yanglong ophiolite. The Yanglong ophiolitic rocks are found as tectonic slices resting on the Neoproterozoic sedimentary and volcanic rocks. These rocks are composed of Cambrian serpentinized peridotite, gabbro, dolerite, and rodingite. The spinels in the serpentinized peridotites have variable Cr^# values (21, 38–46, and 59–61) and display affinity to those in abyssal and forearc peridotites. The dolerites show slight enrichment in Th and have elevated (La/Sm)_N ratios (1.19–2.01), indicating a subduction-related geochemical affinity. The Yanglong ophiolitic rocks have positive zircon <i>ε</i>_Hf(<i>t</i>) values (+10.3 to +18.4) and whole-rock <i>ε</i>_Nd(<i>t</i>) values (+5.3 to +6.7) indicating derivation from partial melting of a depleted mantle source. These results, together with the regional geology, collectively suggest that the Yanglong ophiolite was generated in a forearc setting during the Early Cambrian northward intra-oceanic subduction. It was emplaced onto the Central Qilian Block during the subsequent arc–continent collision, no later than the Early Ordovician.</p>","PeriodicalId":7095,"journal":{"name":"Acta Geologica Sinica ‐ English Edition","volume":"99 2","pages":"409-424"},"PeriodicalIF":3.5,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879985","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}
