| 1 | 台缘微生物礁结构特点及储集层主控因素——以塔里木盆地阿克苏地区下寒武统肖尔布拉克组为例显示文摘基于5条野外露头剖面、162块薄片、12块扫描电镜(SEM)样品及52套孔渗物性数据等资料,分析塔里木盆地阿克苏地区下寒武统肖尔布拉克组台缘微生物礁的结构特点及储集层主控因素。台缘由小型微生物礁群组成,单一礁体可分为前礁相、礁前相、礁脊相、礁后相,镜下可见礁岩具有不同的显微结构。微生物礁发育微生物结构储集空间和非生物结构储集空间,前者包括窗格孔、格架孔、铸模孔及超大溶孔,后者包括微裂缝和缝合线。孔渗数据统计结果表明:于提希剖面微生物礁孔隙度基本小于5%,渗透率一般小于1.0×10^(-3) μm^2,主要为特低孔特低渗储集层,而苏盖特布拉克剖面孔隙度多为3%~10%,渗透率为(0.1~50.0)×10^(-3) μm^2,整体跨度较大,且礁内物性非均质性较强,主要为低—中孔、低—中渗储集层。说明不同微生物礁的物性特征具有较大的差异,同一微生物礁内亦具有明显的储集非均质性。古地貌特征控制微生物礁的发育,沉积作用控制相带的展布及原生孔隙的发育,而溶蚀作用受控于古地貌特征和沉积作用,最终决定微生物礁储集层孔隙的演化。 | 白莹 罗平 王石 周川闽 翟秀芬 王珊 杨宗玉 | 2017 | 石油勘探与开发2017，44，3： | 25 |
| 2 | Current Progress on the Geological Record of Microbialites and Microbial Carbonates显示文摘This paper reviews the current progress and problems in the study of microbialites and microbial carbonates. Microbialites and microbial carbonates, formed during growth of microbes by their calcification and binding of detrital sediment, have recently become one of the most popular geological topics. They occur throughout the entire geological history, and bear important theoretical and economic significances due to their complex structures and formative processes. Microbialites are in place benthic microbial buildups, whereas microbial carbonates can be classified into two categories: stabilized microbial carbonates(i.e., carbonate microbialites, such as stromatolites and thrombolites) and mobilized microbial carbonates(i.e., microbial carbonate grains, such as oncoids and microbial lumps). Various texture, structures, and morphologies of microbialites and microbial carbonates hamper the systematic description and classification. Moreover, complex calcification pathways and diagenetic modifications further obscure the origin of some microbialites and microbial carbonates. Recent findings of abundant sponge spicules in previously identified 'microbialites' challenge the traditional views about the origins of these 'microbialites' and their implications to reef evolution. Microbialites and microbial carbonates did not always flourish in the aftermath of extinction events, which, together with other evidences, suggests that they are affected not only by metazoans but also by other geological factors. Their growth, development, and demise are also closely related to sea-level changes, due to their dependence on water depth, clarity, nutrient, and sunlight. Detailed studies on microbialites and microbial carbonates throughout geological history would certainly help understand causes and effects of major geological events as well as the coevolution of life and environment. | CHEN Jitao LEE Jeong-Hyun | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 14 |
| 3 | 豫西登封寒武系第三统张夏组凝块石灰岩及其控制因素显示文摘依据宏观生长形态和成因环境,豫西登封寒武系第三统张夏组凝块石灰岩可划分为三种型式。小柱状凝块石灰岩以发育分散小柱状凝块为主,形成于潮下带上部中—高能交替的沉积环境;块状凝块石灰岩以不规则块状凝块为特征,形成于潮下带下部低能环境,并受动荡水流影响;树枝状凝块石灰岩以发散的树枝状凝块为特征,形成于正常浪基面之下的深水低能环境。凝块石灰岩发育以风暴成因的竹叶状砾屑灰岩开始,以持续高能环境中发育的厚层鲕粒灰岩的出现为结束。凝块石灰岩形成的水深和水动力条件、依附基底特征和陆源泥质供给等影响凝块石灰岩内部结构和宏观形态,控制着凝块石灰岩的特征发育和整体演化。 | 齐永安 王艳鹏 代明月 李妲 | 2014 | 微体古生物学报2014，31，3： | 12 |
| 4 | Evidence for fault activity during accumulation of the Furongian Chaomidian Formation(Shandong Province,China)显示文摘The Late Cambrian(Furongian)Chaomidian Formation accumulated in an epeiric sea that covered a large part of the North China Plate and extended from China to Korea.The depositional environment of the formation is commonly considered to have been affected by storms that broke up numerous limestone layers,but that was tectonically quiet.It is here argued,however,that some features of the formation-more in particular the many dozens of breccia layers and the occurrence of slid-down limestone blocks that are embedded in autochthonous oolites-can be explained satisfactorily only if some significant fault activity took place during its accumulation.The faulting may have been due to differential loading and subsidence,but an endogenic origin seems more probable.This implies that the structural history of the study area in Shandong Province may need re-consideration. | Ren-Chao Yang A.J.(Tom)van Loon Ai-Ping Fan Zuo-Zhen Han Wei-Wei Tian | 2021 | Journal of Palaeogeography2021，10，4： | 1 |
| 5 | 自生泥晶:过去,现在和未来显示文摘自生泥晶,也称作原地微晶碳酸钙或原地灰泥以区分他生泥晶或异地泥晶,指的是通过无机和/或有机媒介过程作用在原地形成的泥晶碳酸钙。在前人的基础上,对自生泥晶概念的提出和发展进行了概括;对自生泥晶的矿物组成、显微结构、荧光和阴极发光特征进行了总结;对自生泥晶的形成过程和来源(包括生物矿化作用、有机矿化作用和无机沉淀三种方式)进行了探讨;对自生泥晶在不同沉积环境碳酸盐岩中的贡献及其地球化学指示进行了论述;对自生泥晶在地质历史时期的分布做了归纳;最后对自生泥晶的后续研究提出了一些展望。认为正确认识自生泥晶的性质,其形成过程和来源对碳酸盐岩的结构成因分类、地质历史时期生物礁丘的演化和地球化学指示、建筑工程和环境修复、探寻地外生命和油气地质等方面都将产生深远的影响。 | 沈越峰 张乐 沈臻欢 陈亚婕 | 2022 | 沉积学报2022，40，3： | 0 |
| 6 | 岩相特征对海平面升降的响应——以山东苍山寒武系为例显示文摘对于陆表海浅水沉积而言,小幅度的海平面升降即可造成沉积环境和岩相的快速变化。为了研究岩相特征对海平面升降的响应,以出露条件好、岩相变化频繁的山东苍山寒武系为例,通过野外观察、剖面实测,并结合室内薄片鉴定,对研究区寒武系的岩性特征进行了详细分析。将其划分为鲕粒灰岩相、生屑灰岩相、泥灰岩相、灰质砂岩相、微生物灰岩相、页岩相和砂岩相等7种岩相。研究认为,该区馒头组主要发育潮坪—障壁岛—潟湖沉积;张夏组发育局限台地和开阔台地沉积;与馒头组相比,张夏组水动力条件更强;水体能量、深度、光照、清澈程度的旋回性变化,影响微生物的生长以及微生物岩的发育特征。山东苍山剖面寒武系岩相的频繁变化反映了海平面升降和沉积环境的垂向变化,海平面上升晚期或高海平面时期,开阔台地占据主导地位,其高能相带有利于发育鲕粒灰岩、生屑灰岩沉积;开阔台地潮下低能带有利于微生物灰岩丘、疙瘩状灰岩的发育。海平面上升初期或下降期,局限台地、潮坪等主导浅水区沉积,多发育泥晶灰岩、泥质灰岩;潮坪环境水动力条件变化频繁,可发育生屑灰岩、泥晶灰岩、页岩和砂岩等多种类型的沉积岩相。 | 樊爱萍 李诚 杨仁超 韩作振 吴祥生 | 2023 | 沉积学报2023，41，4： | 0 |
