河南省区域地质概况

REGIONAL GEOLOGICAL SURVEY OF HENAN PROVINCE

河南省大地构造跨华北、华南两大板块，属于华北陆块、北秦岭褶皱带、南秦岭褶皱带。地层发育，古生物化石丰富，各期岩浆活动频繁，地质构造复杂。在地壳演化历史中可分为３个阶段，即太古代—中元古代为前造山阶段，晚元古代—三叠纪为主造山阶段，侏罗—白垩纪为后造山阶段。

Henan province, spanning tectonically both the North and South China plates, belongs to the North China block and the North Qinling and South Qinling fold belts. The province is characterized by the occurrence of a relatively complete range of strata, abundant fossils, frequent magmatic activities and complex geological structures. In the crustal evolutionary history three stages can be recognized: the Archean Mesoproterozoic was the pre orogenic stage, the Neoproterozoic Triassic was mainly the orogenic stage and the Jurassic Cretaceous was the post orogenic stage.
