关于景星组的时代和沉积相,存在较大争议。有一种意见认为.它是海相上侏罗统, 与欧洲、非洲、印度等区域的牛津阶(Oxfordian)、启莫里吉阶(Kimmeridgian)相当。后来,景星组双壳类动物群被重新研究。本文在这一基础上,结合岩石地层对比资料,讨论了景星组的时代和沉积相。
There is much controversy about the age and sedimentary facies of the Jingxing Formation. In one opinion, it is a marine upper Jurassic, comparable to the Oxfordian and Kimmeridgian in Europe, Africa and India. Later, King Star group bivalve fauna was re-studied. Based on this foundation, combined with the lithostratigraphic contrast data, we discuss the age and sedimentary facies of the Jingxing Formation.
