半荒漠戈壁地区土壤地球化学找矿研究——以阿拉善右旗塔布格地区为例
A STUDY ON ORE PROSPECTING WITH PEDOGEOCHEMISTRY IN SEMI-DESERT AND GOBI AREA——TAKING TABUGE AREA IN ALIXA RIGHT BANNER OF INNER MONGOLIA AS A CASE
摘要
Abstract
Desert,gobi and mountain are the main topographic features of Tabuge area,Alixa right banner,Inner Mongolia.On the basis of soil geochemical survey at scale of 1∶10000 in Tabuge area,the geological characteristics are summarized and characteristics like the elemental content,anomalous assemblage and soil geochemical anomaly are studied in this article.The results suggest that Au,Ag and Pb have high anomaly intensity,large scale,and obvious concentration center and concentration zone.The multi-element anomaly is well fitted,corresponds to geological structure,and the anomaly verification shows that there are gold-bearing quartz veins,with Au,Ag and Pb as the main ore-forming elements and As,Sb,Bi,Hg,Sn,Cu,Mo,Zn,W the ore-forming indicator elements.Considering the geological ore-forming background and characteristics of geochemical anomaly,two gold-based multi-metal prospecting target fields are set up in the area.It is believed that the main mineral to study should be gold,and the main mineralization type should be the gold polymetallic mineralization of structural hvdrothermal tvoe which is related to tough-brittle tectonic deformation.关键词
