Abstract

The results of palynomorph biofacies analysis of the Lower and Middle Jurassic deposits of Western and Eastern Siberia are presented. A comprehensive study of different groups of palynomorphs (spores and pollens, dinoflagellate cysts, acritarchs, prasinophytes, Zygnematales algae, etc.) was carried out. Detailed analysis of the distribution of separate taxa and quantitative proportions of various groups of microphytofossils in sections of Western and Eastern Siberia allowed combinations of palynomorphs reflecting different facies types to be established. In total, nine ecological-facies associations were distinguished—from continental, coastal marine, and shallow-water to typical marine deep-water.

西伯利亚上，中侏罗统侏罗纪沉积物的生物相分析

摘要

给出了西西伯利亚东部和中西部侏罗纪沉积物的古貌生物相分析结果。进行了不同种类的古植物形态的研究（孢子和花粉，鞭毛藻囊肿，雌性生殖器，藻类，结缕草藻类等）。对西西伯利亚和东部西伯利亚地区不同种类的微植物化石的分类单元和定量比例的详细分析，可以建立反映不同相类型的古朴形态的组合。总共区分了9个生态相协会-从大陆，沿海海洋和浅水到典型的海洋深水。
