湖南及邻区地壳旋转的可能成因、对大地构造演化的影响及其与大规模成矿作用关系初探

在湖南及邻区,无论从地表的地质构造还是地球物理场上,都表现出明显的环状分布特征。这种特征可能是地壳的旋转运动所造成,它对湖南及邻区大地构造的演化、大规模成矿作用等具有重大的影响。本文对这种旋转运动的可能成因,以及所伴随的一系列地质作用、与大规模成矿作用的关系等进行了初步探讨。

Preliminary discussion on possible genesis of crustal rotation, its impact on geotectonic evolution and its relation to large-scale metallogeny in Hunan province and adjacent regions

Hunan province and adjacent regions show ring-form distribution features both on surface geologic structure and geophysical field.Such features might result from the rotation movement of the earth crust and exert serious impact on the geotectonic evolution and large-scale metallogeny in Hunan province and adjacent regions.This paper makes a preliminary discussion on the possible genesis of such rotation movement,as well as the associated series of geologic processes and its relation to large-scale metallogeny in Hunan province and adjacent regions.
