Metallogenic Geological Conditions and Prospecting Potential of the Solonker Magnesite Deposit in Inner Mongolia
摘要
Abstract
The magnesite deposit in the ophiolites of the Solonker suture zone in Inner Mongolia is of great significance to surveys of magnesite,increasing strategy mineral resources and national economy development.This paper presents a systematic investigation and study on this deposit.We have summarized its basic geological characteristics and discussed the metallogenic geological conditions,then analyzed and evaluated its prospecting potential.The magnesite of the Solonker area occurs in the mantle peridotite of the ophiolites in the Solonker Mountains,which is controlled by micro structure in the rock bodies.Mineralization enrichment was constrained by weathering degrees of rocks,and the magnesite was generated by uttrabasic rock weathering-infiltration.There is a coupling relationship between the magnesite formation and ultrabasic rock silicic weathering crust.The upper part of the deposit is the residual of weathering-infiltration product,while the lower part is the magnesite orebody.The magnesite-bearing mantle peridotite rock mass is huge,and many orebodys are present in the deep subsurface with the same metallogenic geological conditions and metallogenic model as the Baxia magnesite in Tibet.So,there is a larger prospecting potential in the Solonker area.关键词
