摘要
利用1:5万高精度航磁数据,结合相关地质、化探、物探等资料,在黑龙江小兴安岭地区优选了709个重点航磁异常。通过综合分析已知矿的航磁异常特征、地质背景、成矿条件等,筛选典型异常进行系统研究,经过查证,取得了较好的找矿效果。总结这些经验,可为今后在本区利用航磁资料综合开展矿产勘查工作开拓思路。
Using the latest 1∶50000 high-precision aeromagnetic data, combining with the related geological, geochemical and geophysical prospecting data, optimizing the 709 key aeromagnetic anomalies in Xiao Hinggan region of Heilongjiang province. Through the comprehensive analysis of the known ore aeromagnetic anomaly characteristics, geological background, metallogenic conditions , etc., screening typical aeromagnetic anomaly system study, after verification, good ore-prospecting results have been achieved. To sum up the experience, can be carried out in the comprehensive use of aeromagnetic data for the future mineral exploration work ideas date in this area.
