摘要
位于中国北方塔里木地台和华北地台之间的北山地区 ,由于地质构造的复杂性 ,长期以来对其基底性质、大地构造归属问题争论较大。本文根据重磁B场特征讨论了其基底性质、地质结构特点 ,并结合地面地质调查资料探讨了北山地区的地质演化过程 。
Beishan area lies between Tarim platform and North China platform.Due to the complexity of its geological structure,the properties of its basement and its geotectonic characteristics have long been problems of controversy.Based mainly on features of its gravity and magnetic field,this paper deals mainly with its basement properties,its geological structure and,in combination with surface geological investigation data,probes into geological evo lution process,thus providing basic evidence for the discussion of relationship between Tarim platform and North China platform.
