摘要
甘新蒙北山地区处于西伯利亚、哈萨克斯坦和塔里木3大古板块的汇聚部位,构造形迹的复杂性致使长期以来对于该区大地构造单元划分不同的学派说法不一,相同的学派在某些具体问题认识上也是各持所见。本文利用甘新蒙北山地区1∶100万、1∶20万区域重力、构造航磁、大地电磁测深和地震测深等地球物理资料,研究了甘蒙北山区域构造、深部构造和区域成矿的关系,也为板块构造研究提供了地球物理场依据。
Beishan area is in the junction part of Siberian Plate, Kazakstan Plate and Tarim Plate, where the structural features is so complicated that the division of geotectonic unit exist the different versions, and there are different opinions even within the same school field. In this essay, the geological data including regional gravity of scale 1：1 000 000 and 1：200 000, aeromagnetic structure survey, magnetotelluric sounding and seismic sounding has been used to study the relations among regional structures, deep structures and regional mineralization, which will provide evidences of geological field for plate tectonic study.
