Soil Geochemical Characteristics And Metallogenic Prognosis In Gan River Area,Inner Mongolia

Gan River area is located in the northeast of Inner Mongolia,belonging to the Oroqen Autonomous Banner of Hulun Buir,Inner Mongolia.The traffic conditions in the area are relatively convenient.The stratum is widely distributed in the area,and the strata exposed mainly to the Mesozoic volcanic strata.The Quaternary is also relatively developed.The research area is located in the middle of the Daxing'anling area,Hualixi period,Yanshan period iron,zinc,tungsten,gold and lead metallogenic belts.The Bokitu-Wuhan tungsten-iron-zinc metallurgy subzone and the Sheltair-Ganghe town iron and zinc The junction of the ore belts is an important favorable area for lead-zinciron mineralization.The Mesozoic volcanic magmatism in this area is intense,and it is a rich area of Cu,Pb,Zn,Mo and other elements.It is also a favorable area for metallogenesis such as gold and nickel.This article is based on the measurement data of 1:50,000 soil geochemistry in the Ganhe region.Analysis and testing of 18 elements such as Au,Ag,Cu,Pb,Zn,W,Mo,Sn,As,Sb,Bi,Hg,Cd,Co,Ni,La,Y,Fe,etc.,preliminary identification and analysis of elemental Distribution and enrichment characteristics,delineation of metallogenic elements anomalies,the use of geological,geochemical exploration and surface engineering and other integrated methods to verify the 1:50,000 geochemical exploration anomalies,the 1:50,000 prospecting prospects for geochemical exploration to make an assessment.Through the measurement of 1:50,000 soil geochemistry in the Ganhe region,a total of 562 anomalous single element areas and 37 general anomalies have been identified,of which three were class B anomalies and 34 were class C anomalies.Through 1:10,000 soil geochemical surveys and surface engineering,it has been verified that there are two 1:50,000 geochemical exploration anomalies.There are 1points in the new discovery of silver deposits,1 of gold mineralization points,1 of Pb and Zn mineralization points,and many sites of mineralization and alteration such as pyrite,magnetite,silicification and epidote.To sum up the metallogenic and metallogenic geological conditions in this area,combined with the geological structure characteristics of the study area,the abnormal combination of the 1:200,000 water system,the comprehensive anomaly of 1:50,000 soil,the 1:10,000 geochemical anomalies,and the mineralized alteration information found in the course of this study.In the process of mineralization and alteration information found in the process,a metallogenic prediction was made and 2 prospective metallogenic prospects were delineated: the Weinhe-Jiwen B-mineral prospecting area and the Busuli North Bmineralization prospect.One step ore to provide the basis.
