广东中坝地区磁场特征及找矿远景区预测

Characteristics of Magnetic Field and Prediction of Ore Prospective Areas in Zhongba Area of Guangdong

通过对广东中坝地区1∶5万地面高精度磁法勘探,获得了该区的磁场数据和磁场分布特征,并对圈定的磁异常进行分析和推断,给出了地质解释。在充分研究磁异常特征的基础上,结合地质和成矿规律的综合分析和研究,圈定了5个有利找矿远景区,为该区后续寻找铜铁钨锡等多金属矿床提供了地球物理依据,直接或间接地指导找矿工作。

This paper introduces that the data and the distribution characteristics of magnetic field are obtained by means of 1∶50 000 high accuracy magnetic prospecting on the ground in Zhongba area of Guangdong province,and geological explanation is given by analyzing and inferring the tagged magnetic anomaly.On the basis of full study of characteristics of magnetic anomaly and combination of the comprehensive analysis and research of geological and metallogentic regularity,five beneficial ore prospecting areas are delineated,which provides geophysical basis for the follow-up of iron,copper,tungsten and tin poly-metallic deposit,then guiding the ore-prospective work directly or indirectly.
