基于地质环境下的区域地层研究

Study on Regional Stratum based on Geological Environment

以区域地层环境为课题,对调查区内郭家山组地层进行调查分析。调查区郭家山组地层隶属于羌塘-扬子-华南地层大区的中、南秦岭-大别山-大巴山地层区,位于郭元-石鸡坝构造混杂岩带北侧的南秦岭地层分区的南秦岭地层小区,其为一套陆棚边缘盆地相、陆棚内缘斜坡相沉积。

this paper mainly based on regi onal stratigraphic environment subject to investigate Guo Jiashan group formation were investigated in the area,certain radioactive-polluted area Guo Jiashan formation belongs to the qiangtang-Yangtze-south China in the formation of regional formation,south qinling-dabie mountain-dabashan mountain area,located in guo yuan-chukar dam south qinling tectonic melange belt on the north side of stratigraphic division of south qinling area,it is a set of shelf marginal basin facies,continental shelf of slope deposition,for your reference.
