【摘要】：产于内蒙古索伦山缝合带蛇绿岩中的菱镁矿,其深入研究对于菱镁矿的勘查、增加战略矿产资源以及国民经济的发展有重大意义。本文对内蒙古索伦山地区菱镁矿进行了系统的调查和研究,通过归纳索伦山地区菱镁矿矿床地质特征,探讨了索伦山地区菱镁矿矿床的成矿地质条件,在此基础上,分析和评价了索伦山地区菱镁矿的找矿潜力。索伦山地区菱镁矿产于索伦山蛇绿岩的地幔橄榄岩内,受岩体内部微小构造控制,矿体贫富受风化程度的制约,受超基性岩风化淋滤形成。菱镁矿与超基性岩硅质风化壳在成因上具有耦合关系,上部为风化淋滤残留物—超基性岩硅质风化壳,下部为风化淋滤的产物—菱镁矿。索伦山地区含菱镁矿的地幔橄榄岩岩体巨大,深部矿体众多,与国内西藏巴夏式菱镁矿在成矿条件和成矿模式方面相一致。所以,索伦山地区具有较大的菱镁矿找矿潜力。
[Abstract]:The study of magnesite in ophiolite of Suolenshan suture zone in Inner Mongolia is of great significance for the exploration of magnesite, the increase of strategic mineral resources and the development of national economy. This paper makes a systematic investigation and study on magnesite deposits in Suolenshan area, Inner Mongolia. By summarizing the geological characteristics of magnesite deposits in Suolenshan area, the metallogenic geological conditions of magnesite deposits in Suolenshan area are discussed. The prospecting potential of magnesite in Suolenshan area is analyzed and evaluated. The magnesite occurs in the mantle peridotite of the ophiolite in the Solenshan area, which is controlled by the micro structure of the rock body, restricted by the weathering degree of the rich and the poor ore bodies, and formed by weathering and leaching of the ultrabasic rocks. Magnesite and ultrabasic siliceous weathering crust have a coupling relationship in origin. The upper part is weathering leaching residue-ultrabasic rock siliceous weathering crust, and the lower part is weathering leaching product magnesite. The mantle peridotite with magnesite bearing magnesite in Suolenshan area is very large and there are many deep orebodies which are consistent with the Baxia magnesite deposit in Tibet in terms of metallogenic conditions and metallogenic model. Therefore, the Suolenshan area has great magnesite prospecting potential.
