CSAMT Geophysical Characteristics and Deep Prospecting Prediction of the Longwan Lead-Zinc Deposit,Cenxi City,Guangxi
摘要
Abstract
The Ordovician strata are the main ore-bearing formations in the Longwan Mining Area.The ore-controlling horizon occurs in an anticlinal structure,with orebodies mainly hosted in the anticlinal axis at a relatively shallow depth;the ore-bearing potential of the anticlinal flanks remains unclear.To verify whether ore exists at depth in the flanks,a controlled-source audio-frequency magnetotelluric sounding(CSAMT)survey was conducted in the mining area.The results show that the CSAMT method can effectively identify deep medium-low resistivity anomalies caused by mineralization.Four low-resistivity anomalies were delineated,and lead-zinc orebodies were intersected at the-500 m elevation level,with a true thickness of nearly 17 m.This provides reliable geophysical evidence and methodological demonstration for deep prospecting in the Longwan Mining Area.关键词
