| 摘 要： | 通过对香毛山一带早—中寒武世黑茨沟组岩石特征、沉积相和沉积构造环境等的调查研究 ,认为黑茨沟组沉积盆地属板内伸展机制下形成的裂谷微洋盆。根据相序变化特征、层序叠置形式、体系域组合特点及界面性质等将该套地层划分为 4个层序 ,并从盆地垂向沉积充填特征等方面探讨了盆地从形成—发展—成熟—萎缩闭合的演化过程。

| Abstract: | By studying on the rocks characteristices,sedimentary faces,sedimentary tectonic environment,ect, Heicigou Formation of early-middle Cambrian Epoch in the Xiangmaoshan district, we hold that sedimentary basin are belong to a rift valley micro-ocean basin, which formed during stretch mechanism of plate. According to the faces-change characteristices, the patent of sequence stratigraphic pile up, assemblage characteristices of system tract, boundary plane properties, ect, we have divided the series of stratigraphy into four sequences, while on the basis of sedimentary filled up basin features in the vertically,we have probed into the basin from sprout to development, mature, shrink close entirely process. |
