固阳-武川韧性剪切带的大地构造意义及金的含矿性一直倍受科研和勘查部门的关注,许多学者曾从不同角度或以不同研究方法对其进行过论述。作者通过附近部分地区的详细地质填图研究,对其大地构造意义赋予新的内涵,认为该剪切带是相互分离的两个古陆块在晚太古代末一早元古代初碰撞拼贴的基础上,经早元古代中晚期近东西向左旋剪切改造的接触界线,色尔腾山岩群和乌拉山岩群是晚太古代不同大地构造环境的产物。
The tectonic significance and gold mineralization of the Guyang-Wuchuan ductile shear zone have always been of concern to the scientific research and exploration departments. Many scholars have discussed it from different angles or with different research methods. Based on the detailed geologic mapping in some parts of the world, the author gives new connotations to the tectonic significance of the tectonic setting. The authors consider that the shear bands were separated from each other on the basis of the late Early Archean-Early Early Proterozoic collision collage , The boundary line of east-west-left-lateral shear deformation in the early Early Proterozoic, the Serteng rock group and the Wulashan rock group are the products of different Archean tectonic settings in the Late Archean.
