内蒙古自治区贺根山铬铁矿,自1954年以来相继作了不少研究工作,积累了许多实际资料,对超基性岩和铬铁矿成因也提出了一些认识。本文根据1981年地质矿产部和法国地质矿产调查局的协定,在合作开展贺根山地区蛇绿岩和铬铁矿成因的专题研究中所取得地质资料的基础上,参考内蒙古自治区地质矿产局的资料,就贺根山铬铁矿形成条件和成因类型提出一些新认识,供讨论。
The Hegenshan chromite in Inner Mongolia Autonomous Region has done a lot of research work since 1954, accumulated many actual data, and also made some cognitions on the origin of ultrabasic rocks and chromite. Based on the geological data obtained from the special study on the origin of ophiolite and chromite in the Hegengshan area in accordance with the agreement between the Ministry of Geology and Mines and the French Bureau of Geology and Mineral Resources in 1981, reference is made to the data of the Bureau of Geology and Mineral Resources of Inner Mongolia Autonomous Region , Put forward some new understandings on the Hengenshan chromite formation conditions and genetic types for discussion.
