为了查明地质构造、研究区域成矿规律、寻找铜镍矿产资源,充分利用区域物探信息,无疑会深化地质认识、开辟新的找矿途径。根据吉林省重力、航磁资料,从场的平面特征差异和特征规律分析入手,总结基性超基性岩的分布特点,对寻找与基性超基性岩有关的矿产资源是十分必要的。本文旨在利用百万分之一重力及五十万分之一航磁资料划分重、磁场特征线,并与已知岩体进行综合对比,寻求其空间分布关系,为比较全面的认识该区基性超基性岩体分布特点提供物探依据,为寻找新岩体提供线索。
In order to identify the geological structure, study the regional metallogenic regularity, look for copper-nickel mineral resources and make full use of regional geophysical information, it is undoubtedly to deepen geological understanding and open up new prospecting ways. According to the gravity, aeromagnetic data in Jilin Province, the differences of planar features and the law of features from the field, it is necessary to summarize the distribution characteristics of the basic ultrabasic rocks and find the mineral resources related to the basic ultrabasic rocks. This paper aims to use the one millionth of gravity and one hundred thousandth of the aeromagnetic data to divide the heavy and the magnetic field characteristic line, and with the known rock mass comprehensive comparison to find the spatial distribution of relations, for a more comprehensive understanding of the area The characteristics of the distribution of basic ultramafic rocks provide geophysical evidence and provide clues for finding new rock mass.
