摘要
通过对青藏铁路沿线航磁反映的大地构造背景的综合分析,对青藏铁路沿线找矿远景进行了预测。依据不同的成矿地质背景和航磁反映的构造—岩浆—热液环境、局部异常特征,结合大地构造位置,将研究区划分为7个成矿带。圈定铁、铜、铅、锌、金、银、铬等多金属找矿远景区125个,其中一级找矿远景区49个,为该地区地质调查和矿产资源评价提供了重要信息。
Based on a comprehensive study of the geotectonic background reflected by the aeromagnetic data, this paper made a prediction of the ore-search prospect along the Qinghai-Tibet railway. According to geological background of mineralization, teetonic-magmatic-hydrothermal environment and characteristics of magnetic anomalies, combined with the tectonic position, the authors divided the area into 7 metallogenic behs, and delineated 125 prospective areas of iron, copper, lead, zinc, gold, silver, chromite and polymetallic resources, in which 49 belong to first grade areas.
