天山西南段乌恰-柯坪地区航磁磁场特征与成矿远景预测

Characteristics of aeromagnetic field and metallogenic prognosis of Wuqia-Keping area, southwestern part of Tianshan

本文以 1 998年 1∶2 0万航空磁测资料为基础 ,参考地质和化探资料 ,对工作区磁场特征、岩浆岩、断裂构造与矿产分布的关系进行探讨 ,研究地质成矿环境 ,建立寻找热液型和火山 沉积型的铜、铅、锌、金、铁、锰矿找矿标志 ,对本区找矿远景进行了预测。

Based on 1∶200000 aeromagnetic survey data performed in 1998, and referred to materials of geolo gic and geochemical prospecting of the working area, this paper discusses the relationship between the characte ristics of magnetic field, magmatic rocks, fault structure and the distribution of mineral resources, and investigates the geologic metallogenic environments, and sets up the prospecting criteria for hydrothermal and volcanic sedimentary copper, lead, zinc, gold, iron,manganese deposits, then makes the prognosis of the prospecting potential of the working area.
