TX1井卡洛夫-牛津阶古生物特征

The Palaeontological Characteristics of the TX1 well-Oxfordian

本文研究的目标为中上侏罗统卡洛夫-牛津阶,通过系统岩芯资料、薄片和古生物鉴定的综合分析Ag井卡洛夫-牛津阶所出现的生物主要有棘屑、介形虫、腕足、苔藓、有孔虫、骨针、腕足、腹足、海百合、藻等。大多数以浅海各类窄盐度生物及生物碎屑为主,广泛分布于台地相中。在此基础上,我们可以得出该目标层中的古生物特征,以及古生物的沉积环境。

The object of this research is the Karlog-Oxfbrdian of middle and Upper Jurassic. Through the comprehensive analysis of the core data, thin slices and paleontological identification of the system core, the Karloft -Oxtordian of TX1 well mainly occurs spinous chips, oc- topus, brachiopod, moss, foraminifera, bone needles, brachiopod, gastropods, sea lilies, algae and so on. Majority of them are shallow ocean sa- linity organisms and biodetritus that are wide distributed in the platform facies. On this basis,We can get the paleontological characteristics of the target layer and the sedimentary environment of palaeontology.
