中国大陆地区三叠纪震积岩研究及触发机制探讨

Seismites Research and Its Trigger Mechanism of the Triassic in China's Mainland

通过对中国近30年来有关三叠纪震积岩的相关记录进行汇总总结,总结出三叠纪震积岩发现地点主要集中在鄂尔多斯盆地盆地东南缘、川西龙门山地区、青藏高原东北部及山东淄博盆地、滇西地区。结合三叠纪中国大陆构造运动特征,对三叠纪地震事件发生的触发机制从整体范围内进行了探讨,并以鄂尔多斯盆地油气分布规律为例对地震事件对油气藏分布规律的影响进行了研究探讨。

By summarizing the relevant records of Triassic Seismites in China in the past 30 years, it is concluded that the Triassic seismites are mainly found in the southeastern margin of the Ordos Basin, Longmenshan area in Western Sichuan, northeastern Qinghai-Tibet Plateau, Zibo basin in Shandong Province and Western Yunnan Province. Based on the characteristics of the tectonic movement of the Triassic in China, the trigger mechanism of the Triassic seismic events is discussed in the whole range, and the impact of earthquakes on the distribution of oil and gas is also summarized, such as Ordos Basin.
