生物矿物与古环境重建研究及其存在的几个问题.自然科学与博物馆研究，北京，高等教育出版社： 146 - 151 - Suzhou museum and kunshan cultural relicsadministrative office , cooperated with each other , excavated chuodun site for the fourth time in 2001 , and the author participated in its research on palaeoenvironment changes
苏州博物馆与昆山文物管理所合作， 2001年对太湖流域大型考古遗址? ?绰墩遗址进行了第四次发掘，笔者参与了其中古环境演变的研究。 - From sedimentology symbol such as rock assembled , sediment gradus , sandstone grading analysis , protogene sedimentary structure , ichnofossile and logging facies etc and palaeoenvironment background , it is confirmed that shen84 - an12block s34 segment is braid river delta system , not fan delta system ( abrupt slope ) . then it can be more partition as braid river delta plain sedimentary assembled , delta front sedimentary assembled and prodelta sedimentary assembled on core and log assembled . and delta plain sedimentary assembled can be identified four microfacies : braided distributary channel , crevasse splay , overbank deposits and interdistributary bay
沉积微相研究是储层非均质性研究的基础，研究区有丰富的岩芯资料和测井资料，通过岩石组合、沉积韵律，砂岩粒度分析、沉积构造、古生物遗迹和测井相等沉积学标志，结合古环境背景，确定沈84 ?安12块s _ 3 ~ 4段为辫状河三角洲体系，而不是前人所认为的扇三角洲(陡坡型)体系，在岩芯和测井组合上可进一步划分为辫状河三角洲平原沉积组合、三角洲前缘沉积组合和前三角洲沉积组合，其中三角洲平原沉积组合又可识别出辫状分流河道、决口扇、分流河道边部和分流间湾四种微相类型；三角洲前缘沉积组合识别出水下分流河道、水下分流河道边部和分流河口坝三种微相。 - Eight aspects related to the study of early precambrian metamorphic stratigraphy are dealt with in this paper : general situation of the study ; complexity of the stratigraphy and difficulties of the study ; thoughts and methods of the study ; division of rock suite , rock group and complex rock ; researches on important regional discordances ; types and characteristics of protolith and recovery of palaeoenvironment ; correct differentiation of the metamorphic strata , ttg rock system and other metamorphic plutonic rocks ; determination of the ages of the metamorphic strata
