秦岭是我国南北地质分野及衔接地带,又是一个重要的金属及非金属成矿带。七十年代中期开始,国内一些地质学家先后引用板块构造理论对本区研究。但是,由于一些重大基础地质问题未获解决,故对构造演化历史及构造单元的划分尚有较大分歧。笔者等近年来用板块构造的研究方法对本区进行了一些工作,在综合前人资料的基础上,提 Qinling is a geological separation and convergence zone between North and South China and an important metal and nonmetal metallogenic belt. Seventies metaphase, some domestic geologists have cited plate tectonic theory of the study area. However, there are still some major differences in the history of tectonic evolution and the division of tectonic units because some major basic geological problems have not been solved. In recent years, the author has done some work in this area with the research methods of plate tectonics. On the basis of synthesizing the previous data,
