内蒙古镶黄旗毕山地区土壤地球化学特征及找矿方向
Soil geochemical characteristics and prospecting orientations in the Bishan area,Xianghuang Banner,Inner Mongolia
摘要
Abstract
To determine the optimal prospecting target in the Bishan area,Xianghuang Banner,Inner Mongolia,this study conducted a geochemical survey at 1∶10,000 scale.Using multivariable statistical analysis,this study analyzed 14 elements(i.e.,Au,Ag,Cu,Pb,Zn,Mn,Mo,Li,W,Sb,Bi,B,Hg,and As)in soil samples from the study area.The results indicate that six elements,inclu-ding Au,Ag,Pb,Zn,Li,and As,exhibited high enrichment degrees,suggesting their significant metallogenic potential.The anoma-lies of high-content elements are principally dictated by the outer contact zone between tuffs/tuffaceous volcanic breccias and granites in the Lower Permian Sanmianjing Formation.The ore-forming elements are primarily controlled by the NW-trending fault zone.Altera-tions like silicification,binarite,pyrite,galena,and sphalerite alterations serve as principal prospecting markers.Based on the geolog-ical conditions for mineralization in the Bishan area,this study delineated three composite anomalies and two prospecting targets,with Ag ore bodies discovered through engineering validation.Soil geochemistry proves crucial for the successful identification of polymetallic ore bodies,thereby providing a significant foundation for subsequent mineral exploration efforts.关键词
