Sedimentary environment and micro-sediment characteristics of Oligocene source rocks in Qiongdongnan Basin

LIU Chuanlian(State Key Laboratory of Marine Geology,Tongji University,Shanghai 200092,China)  
High resolution study on the source rocks in Yacheng Formation and Lingshui Formation of Qiongdongnan Basin was carried out by using the backscattered electron imaging(BSEI) technology.The study results show that the organic matters of these source rocks include foraminifers,calcareous nannofossils,organic matter lamination and terrigenous plant debris.The organic matters were distributed in source rocks with four types of continuous lamination,intermittent lamination,scatter and flocculation.According to the composition and distribution characteristics of organic matters,five types of source rocks in Qiongdongnan Basin can be subdivided,including the continuous lamination mudstone,intermittent lamination mudstone,foraminiferal and calcareous nannofossil mudstone,terrigenous plant debris mudstone and scattering organic matter mudstone.The quantitative analysis on calcareous nannofossil of the Oligocene rock samples obtained from 5 wells was carried out.According to the nannofossil assemblages,abundance and diversity,it is suggested that the sedimentary environments of the Oligocene source rocks are the littoral environment and shallow sea environment.
