摘要
本文论述了华南地块二叠系孤峰组和大隆组放射虫硅质岩的时-空结构,分布规律和沉积特征.认为放射虫硅质岩的堆积是由于位于赤道附近的深断陷中冷热海水对流造成的.早二叠世晚期开始的、因南北向拉张作用造成的规律性裂解遍及整个华南地块.
The paper discussed about the time and space, distributive pattern and sedimentary characteristics of the radiolarian siliceous rocks in Permian Gufeng and Dalong Formations of south China massif. The accumulation of the siliceous rocks is the result of the convection of hot and cold sea water in the deep falldown faulted subsidence near the equator, which began at the late stage of early Permian when regular fracturing and separation due to south-north tension took place all over the south China massif.
