摘要
华北地台东部,燕山期、喜山期构造变动强烈。三叠系遭受了严重的剥蚀,残留面积狭小而零星,尤其在太行山北段、燕山、辽、鲁等地所存无几。因而造成了一种错觉,以为地台东部是印支期古隆起。三叠系很不发育,只是在个别地点散布着一些局限性的沉积。然而这个问题事关华北地台地质历史之真貌,且与油、气资源评价、煤种预测密切相关。因此,有研究之必要。
Abstract
This article presents the distribution pattern of the Triassic System in Southern North-China.It is stated that the Triassic System in the area studied is an extensive and stable clastic formation of continental facies.The original depositional thickness and settings have been reconstructed through analyzing the burial-thermal evolutional history.
