摘要:
黔南祥摆组的化石资料稀少且以植物化石为主,在独山县羊凤乡祥摆组中发现了一个海相动物群,主要化石有腕足类、珊瑚类、苔藓虫类、头足类和遗迹化石,其中以腕足类最为丰富。在鉴定分析所发现化石的基础上,结合该动物群所在层位的岩性特征、矿物特征和区域上该时期的沉积特征,采用古生态学分析方法,认为该动物群生存环境为一个淡化潟湖。区域上,该潟湖主要位于平塘县与独山县之间,而构成潟湖与外海的障壁则主要位于摆者至麻尾一线东北,呈北西向延伸;在北部兔场附近祥摆组已演变为以泛滥平原沉积为主。潟湖范围内现今构造形态完整,同时这种局限低能的沉积环境可以形成良好的烃源岩,因此它们在区域上的分布对岩相古地理和油气生储盖组合研究具有重要意义。
Abstract:
Xiangbai Formation was scarce of the fossil records which most parts were constituted of phytolite in South Guizhou. A marine fauna, which was comprised of the brachiopod, the coralline, the bryozoan, the cephalopod and the trace fossils, was discovered in Xiangbai Formation of Yangfeng Village of Dushan County. According to the lithologic, mineral and deposit characteristics of the neighborhood in the horizon of marine fauna, on the basis of the fossils' identify with the palaeoecology method, the results showed that the marine fauna lived in a desalted lagoon which mainly located between Pingtang County and Dushan County. The barriers of lagoon and open sea were mainly located in the northeast of Baizhe-Mawei with NW extension. In the north part, Xiangbai Formation had evolved with the main flood plain deposits near the Tuchang. The structure within the lagoon was complete, and the limited low-energy environment could form well hydrocarbon source rock. Therefore, the distribution has great significance on the study of lithofacies and paleogeography as well as the assemblage of the source-reservoir-seal association in oil and gas fields.
