ON THE ORIGIN, DISTRIBUTIVE PATTERN AND TECTONIC CONTROL OF SILICEOUS ROCKS IN GUFENG AND DALONG FORMATIONS, SOUTH CHINA

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.
