我国若干裂谷构造特征及其成矿作用

从基底构造、深大断裂、岩相古地理、岩浆活动、古地磁特征和裂谷型层控矿床比较等６个方面论证泰岭裂谷的存在，以古地磁成果为主导，探讨了秦岭裂谷的发生发展演化，到加里东末期裂谷曾锁闭，海西印支期再复合，从而有秦岭裂谷型层控铅锌矿床的形成，直到 印支末期裂谷两侧板块才碰撞对接在一起，文章最后论述了裂谷构造与成矿关系，我国若干裂谷构造特征与世界大陆裂谷的比较。

STRUCTURAL CHARACTERS AND THEIR MINERALlZATION IN SOME RIFTS IN CHINA

The existence of the Qinlin Rift has been demonstrated based upon the characters of basement stracture,deep-seated fauIt,lithofacies and paleogeography ,magmatism, paleomagnetism and the comparison betweenstrata-bound ore deposits of rift type. The development and evalution of the Qinlin Rift discussed taking theresearch resuIts as dominant factors indicate that the rift was closed to the end of Caledonian epoch and re-vived during Hercynian and Indo-chinese epoch,Therefore the strata-bound lead-zinc deposits of Qinlin Rifttype were formed.The plates on the both sides of the rift came into collision each other upto the end of Indo-chinese epoch.Finally the relationship between rift and mineralization were discussed,and the characters ofsome rifts in china were compared with those of some continental rifts in the world.
