内蒙古东乌旗巴润查干陶勒盖地区物化探异常特征及找矿远景

摘要

内蒙古东乌旗巴润查干陶勒盖地区位于二连-东乌旗成矿带东段，具有良好的成矿地质背景，晚华力西期花岗岩、石英二长斑岩侵入体及各类晚期脉岩伴随北东向断裂构造侵入安格尔音乌拉组地层中，具有十分有利的成矿地质条件。1：5万及1：1万土壤地球化学异常元素主要为Pb、Zn、Cd、Cu等，浓集中心明显，套合较好。1：5万航磁局部异常及1：1万地面高精度磁测异常均与北东向构造岩浆活动密切相关。1：1万地质测量圈定的地表矿化蚀变带与上述物化探异常形态基本一致。通过分析研究区的控矿地质条件及物化探异常特征，认为研究区热液型 Pb、Zn 多金属矿床具有良好的成矿远景，有进一步工作价值。%Mongolia Dongwuqi Barun Tsagaan Tolgoi area has a good geological setting which is located in the east of Erlian-Dongwuqi metallogenic belt.Granite intrusions and masanophyre intrusions in late Variscan and various late dikes intrude in Ingres Ulla group along with northeast-trending faults, this area has a very favorablemineralization geological condition. The soil geochemical test of Barun Tsagaan Tolgoi area at 1:50000 and 1:10000 points out that the major geochemical anomaly elements are Pb,Zn,Cd,Cu,etc.,and the elements are obviously center-concentrated,fit better.Aeromagnetic exploration at 1:50000 and ground high-precision magnetic measurement at 1:10000 show that magnetic anomalies are closely related to the magmatic activities in the northeast.Mineralized alteration zone on ground outlined by 1:10000 geological survey are agreed with the above geophysical and geochemical anomalies.Through the analysis ore controlling geological conditionand geophysical and geochemical anomalies of the study area,we think that this area has a good future on lead-zinc-polymetallic deposit and it worh studying further.
