长江中下游庐枞矿集区东北缘蒋家冲地区多金属矿地球物理特征及找矿模式
Geophysical characteristics and prospecting model of polymetallic deposits in the Jiangjiachong area,northeastern Lu-Zong ore cluster,middle-lower Yangtze River metallogenic belt
摘要
Abstract
The Jiangjiachong area in Anhui Province,located in the northeastern Lu-Zong volcanic basin,exhibits complex multi-stage mineralization processes with diverse ore body types.This study systematically analyzes geophysical anomaly characteristics within the survey area,summarizing the integrated gravity-magnetic-electrical anomaly patterns of typical deposits in the region.By examining the spatial distribution and geological genesis of known ore deposits,we establish a geological-geophysical model for mineralization within and surrounding the Jiangjiachong area.The model enables systematic screening of comparable integrated anomaly patterns across the study area to guide exploration targeting.Validation drilling at integrated anomaly site ZK06 successfully intersected a porphyry-type lead-zinc ore body with 48.47m apparent thickness,confirming the model's predictive capability for concealed mineralization.关键词
