安徽巢湖市二叠系栖霞组生物碎屑的数量及其地质意义
|
摘要
巢湖凤凰山东南坡二叠系下统栖霞组底部为梁山段含劣质煤线,上部为灰岩夹有薄层炭质泥页岩,顶部为含燧石结核灰岩,根据实测地层剖面,发现生物碎屑含量具有先增加后减小的规律。结合前人对全球栖霞期古气候、古海洋的研究,认为栖霞期海平面整体上升,在海侵的过程中出现多次海退,沉积环境为澙湖—局限海湾—开阔台地—碳酸盐岩台地。根据燧石结核主要为热液成因的认识,推断二叠纪栖霞组生物碎屑的变化可能与260Ma峨眉山地幔柱前期地质作用有关。
The bottom of the Lower Permian Qixia Formation is inferior coal streak contained Liangshan Member,upper part is limestone intercalated with carboniferous thin argillutite,the top is flint nodule contained limestone in southeast slope of the Fenghuangshan,Chaohu City.According to measured stratigraphic section,has found a regular pattern of bioclast quantity increasing in the lower part then decreasing upwards.Based on previous studies on global paleoclimate and paleooceanography during the Qixia age,considered that as a whole,sea level was rising at that time,but multiple regressions had happened in the transgression process;sedimentary environments were lagoon-confined bay-open platform-carbonate rock platform.Based on the cognition of flint nodule hydrothermal origin,has deduced that Permian Qixia Formation bioclast quantity variation may related to the preceding geological process of the Emeishan mantle plume 260Ma before.
