The Tarim Basin is the only petroliferous basin enriched with marine oil and gas in China.It is presently also the deepest basin for petroleum exploration and development in the world.There are two main sets of marine Source Rocks(SRs)in the Tarim Basin,namely the high over-mature Cambrian-Lower Ordovician(∈-O_(1))and the moderately mature Middle-Upper Ordovician(O_(2-3)).The characteristic biomarkers of SRs and oils indicate that the main origin of the marine petroleum is a mixed source of∈-O_(1) and O_(2-3) SRs.With increasing burial,the hydrocarbon contribution of the∈-O_(1) SRs gradually increases.Accompanied by the superposition of multi-stage hydrocarbon-generation of the SRs and various secondary alteration processes,the emergence and abnormal enrichment of terpenoids,thiophene and trimethylaryl isoprenoid in deep reservoirs indicate a complex genesis of various deep oils and gases.Through the analysis of the biofacies and sedimentary environments of the∈-O_(1) and O_(2-3) SRs,it is shown that the lower Paleozoic high-quality SRs in the Tarim Basin were mainly deposited in a passive continental margin and the gentle slope of the platform,deep-water shelf and slope facies,which has exhibited a good response to the local tectonic-sedimentary environment.The slope of the paleo-uplift is the mutual area for the development of carbonate reservoirs and the deposition of marine SRs,which would be favorable for the accumulation of petroleum.Due to the characteristics of low ground temperature,the latest rapid and deep burial does not cause massive oil-cracking in the paleo-uplift and slope area.Therefore,it is speculated that the marine reservoirs in the slope of the Tabei Uplift are likely to be a favorable area for deep petroleum exploration,while the oilcracking gas would be a potential reserve around the west margin of the manjiaer Depression.Hydrocarbons were generated from various unit SRs,mainly migrating along the lateral unconformities or reservoirs and the vertical faults.They eventually brought up three

Mesoproterozoic marine organic-rich rocks are widely distributed in the North China Craton,include the Gaoyuzhuang(GYZ),the Hongshuizhuang(HSZ),and the Xiamaling(XML)formations.According to the T;value and isomerisation ratio of C;homohopanes,the XML,HSZ,and GYZ samples were in low mature,mature and high mature stage,respectively.Biomarker distribution in extractable organic matter(EOM)of three Mesoproterozoic organic-rock samples in different maturity were analysed to reveal the organic precursor and preservation pathway of in the Mesoproterozoic Combined with gold-tube pyrolysates of three Mesoproterozoic samples,it could further illuminate the chemical composition of Mesoproterozoic kerogen,given excluding.The results indicated that the three formations were all deposited under reducing condition and their organic precursors mainly were some aquatic organisms.High content of rearranged hopanes was detected in EOM of XML and HSZ samples,whereas they were relatively low in the high mature GYZ sample.Contrast to that in EOM,the relative concentration of rearranged hopanes sharply decreased in the gold-tube pyrolysates of the XML kerogen,then slightly increased but was still significantly lower than the EOM of XML sample,which indicated that catalysis of clay minerals in the early diagenesis only changed the chemical composition of the unstable functional groups of the kerogen during the preservation.Due to the thriving heterotrophic microbes and low sink rate of particulate organic matter during the Mesoproterozoic,primary producers suffered extensive degradation during sinking process,only some resistant biopolymers lacking of lipid compounds survived from heterotrophic degradation,while heterotrophic microbes contained more proportion of organic precursors.Abundant pristane(Pr)and phytane(Ph)were only released in high mature stage because of the protection of the macromolecular structure of resistant biopolymers which prevented biomarkers from being altered by the thermal stress.The absence of 13α(n-alkyl)-tric

塔里木盆地寒武系—奥陶系烃源岩的生源特征及其对超深层油气贡献是塔里木盆地超深层海相油气勘探面临的关键地质问题。根据分子与同位素地球化学分析和生烃热模拟实验研究,系统梳理油源对比的地球化学参数,认为原油中C_(26)~C_(30)甾烷的分布、伽马蜡烷指数、三环萜烷与五环萜烷比值和正构烷烃同位素等油源示踪指标,易受热演化程度、生物降解和水岩氧化还原作用影响,掩盖母源输入和沉积环境的差异。正构烷烃奇偶优势,异常的三环萜烷分布,全油和正构烷烃δ^(13)C同位素明显偏重以及高含量的多环芳烃的出现主要归因于高过成熟热演化作用、低温热液或侵入岩浆等异常热事件的影响,而并非反映■—O_(1)烃源岩中生烃母质的地球化学特征。局部的硫酸盐热化学还原反应导致无机硫并入形成次生的噻吩类化合物,造成有机硫同位素值明显升高,无法反映母源特征,目前被选做寒武系典型烃源岩和端元油的生烃母源特征很可能是经历多种次生地球化学作用改造的结果。通过分析寒武系—奥陶系两套中等热成熟度烃源岩的形成环境和生物母质类型,表明塔里木盆地台盆区寒武系—奥陶系烃源岩的油源特征差异主要受控于沉积相,塔北中西部海相原油主要与透光厌氧环境烃源岩有关,塔中地区原油主要来源于深水盆地相烃源岩。重新建立不同物化性质原油与高过成熟烃源岩之间可靠的油-源对比参数,需要同时考虑成熟度和次生改造等复杂地球化学作用的多重影响才能确定其成因和来源。

价值共毁是在共享住宿服务生态中较为普遍的现象,影响了数字经济和平台经济的高质量发展。先前大量研究探索了共享经济中的价值共创机制,但较少关注共享平台服务系统中的价值共毁问题,尤其缺乏探讨共享住宿平台参与者的价值共毁具体影响因素与作用机理。基于脚本理论,文章以共享住宿平台的主要参与者为研究对象,采用混合方法探究平台价值共毁的前因,并从平台房客角度验证了价值共毁的作用机理模型。通过探索性案例研究,文章发现,共享住宿平台中的价值共毁主要由平台主要参与者互动过程中的服务脚本不一致造成,并将价值共毁的前因归纳为平台、房东和房客3个维度8个类别,包括平台机制、平台本土化、房东服务能力、信息不对称、房东态度、房客期望、房客态度和房客规范。在探索性案例研究的基础上,文章从平台房客角度开发了包含4个构念18个题项的共享住宿平台价值共毁量表,构建了共享住宿平台价值共毁作用关系模型。研究发现:服务脚本不一致显著正向影响价值共毁感知(包括服务目标阻止和服务净亏损);价值共毁感知显著正向影响价值共毁行为。其中,服务目标阻止在服务脚本不一致与价值共毁行为之间具有显著中介作用。研究结果对于指导和规范我国共享住宿、共享出行等数字经济新业态的高质量发展和可持续发展具有重要理论和实践意义。

Zircon U-Pb Geochronology of Baoyintu Group in the Northwestern margin of the North China Craton and Its Geological Significance

引用

地球科学学刊:英文版 2023年第5期34卷 1511-1526页

作者： Chengwu Ding Yifei Liu Pan Dai sihong Jiang Chengzhen Ding School of Resources and Environmental Engineering Shandong University of TechnologyZibo 255000China MNR Key Laboratory of Metallogeny and Mineral Assessment Institute of Mineral ResourcesChinese Academy of Geological SciencesBeijing 100037China Geophysical Research Institute of BGP Inc.China National Petroleum Corporation Zhuozhou 072751China

The Baoyintu uplift is located at the northwestern margin of the North China Craton(NCC). The affiliation and evolution history of the uplift have been unresolved until now. Here we present LA-ICP-MS and SHRIMP U-Pb data for zircons extracted from samples of monzogranitic orthogneiss and the Baoyintu Group in the uplift. The 1 679 ± 13 ma date for the orthogneiss demonstrates that Late Palaeoproterozoic rocks do exist in the uplift. The ca. 1 413 ma minimum age of detrital zircons in metasedimentary rocks shows that the maximum age of the Baoyintu Group is Mesoproterozoic. The age distribution of detrital zircons in the first unit of the Group form clusters at ca. 2 680, 2 450, 1 800 and 1 560 ma, which partly correspond to tectonic-magmatic-metamorphic events previously recognised in the NCC, and show that the metasedimentary rocks are largely sourced from different parts of the NCC. These confirm that the Baoyintu uplift is part of the NCC. Amphibolite with a dolerite protolith from the third unit of Baoyintu Group shows evidence for metamorphism during ca. 877–851 ma. This combined with published geochronological data indicate the presence of Neoproterozoic magmatic and metamorphic events in the NCC, which significantly increases our understanding of the Proterozoic tectonic evolution of the region and its possible correlation with the Rodinian Supercontinent.

To develop a national reference panel for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)antigen detection kit and establish a quality standard.The cultures of SARS-CoV-2 and other pathogens were collected to establish a national reference panel for SARS-CoV-2 antigen detection.The stability and homogeneity of the reference panel were evaluated.Based on World Health Organization(WHO)guidance and nucleic acid quantitative results,a quality standard reference panel was established.Currently,three generations of SARS-CoV-2 antigen national reference materials with batch numbers 370095–202001,370095–202202,and 370095–202203 have been successfully established.These national reference panels comprised 8 positive samples,20 negative samples,1 repetitive sample,and 1 lower detection limit sample.The stability and homogeneity of the reference panel meet the requirements.The quality standards are as follows:the positive and negative coincidence rates are 8/8 and 20/20,respectively.The 10 test results of the medium and low-concentration repetitive reference materials should be positive,and the color rendering should be uniform(or the coefficient of variance should not be higher than 20.0%).The lower detection limit should be at least 5×105 U/mL(equivalent to copies/mL),and higher concentrations above the lower detection limit must be positive.A national reference panel for the SARS-CoV-2 antigen detection kit has been established.As the standard of SARS-CoV-2 antigen reagents,the reference panel has played a crucial role in the pre-marketing quality evaluation and post-marketing quality supervision in China.
