内蒙古喀喇沁旗金蟾山金矿构造叠加晕异常特征及找矿预测
Structural superimposed halo anomalies and prospecting prediction of Jinchanshan gold deposit,Harqin Banner,Inner Mongolia,China
摘要
Abstract
The Jinchanshan gold deposit,identified as a magmatic-hydrothermal vein-type gold deposit associated with Yanshanian magmatism,is located in the Chifeng-Chaoyang gold ore concentration area within Harqin Banner,Inner Mongolia.The ore bodies in the deposit primarily occur in the fault structural zone of the Anjiayingzi pluton.This study conducted a systematic analysis of the struc-tural superimposed halo anomalies of the Dawa and Limazigou ore sections from south to north in the eastern mineralized zone in the Jin-chanshan gold deposit.Results indicate that the axial zoning and characteristic parameters of primary haloes in Jinchanshan gold deposit differ from the typical high-,medium-,and low-temperature element axial zoning sequence in hydrothermal deposits.The overlapping of high-temperature and low-temperature elements,suggests multi-stage and multi-phase mineralization processes.For the first time,this study analyzed the correlation between elements using element correlation curves at varying elevations.F and Ba were identified as front halo elements,Au,Cu,and Ag as near-ore halo elements,and Co,Ti,and V as tail halo elements.By establishing a structural superimposed halo model,this study determined prospecting target areas.Mining validation indicates that the identified ore-discovery middle section aligns with the predicted target area.关键词
