摘要
提出西秦岭造山带以新发现的黑水断裂为南界,并将它归属古扬子大陆的组成部分。其演化过程经历了前加里东期(武陵期—晋宁期)、加里东期、华力西期和印支期等多个阶段构造变革,后经历燕山期和喜马拉雅期改造呈现出现今地质构造景观。
The present paper considers the West Qinling orogenic bait as a tectonic unit of the yangtze land and regards recently discovered Heishui fault as its southern boundary.Tectonic events from Pre-Caledonian(Wuling-Jinning)to Himalayan epochs are res POnsible for the present geologic landscape of the orogenic bait.
