内蒙古乌拉特后旗查干德尔斯钼矿地质特征研究

Study on Inner Mongolia wulatehouqi Chagandeersi deposit geological characteristics

我国钼资源极为丰富,金属总储量均为340多万吨,占世界钼储量的30%,仅次于美国和智利,居世界第3位。本矿区钼矿体主要赋存于绢英岩化二长花岗岩内和石英脉中,少数赋存于二云石英片岩内。绢英岩化二长花岗岩既是围岩也是含矿母岩,钼矿体与围岩界线呈渐变关系,钼矿体由于赋矿深度在20m以下,钼矿石为原生矿石,钼呈硫化物形式存在。矿石类型为原生硫化钼矿石。

China＇s molybdenum resources are extremely rich, the total metal reserves are about 3400000 tons, accounting for the world＇s Molybdenum reserves of 30%, second only to the United States and Chile, ranking the world＇s third. The mining area of molybdenum ore bodies mainly occur in the following two Juanying granite and quartz vein, a few occur in two mica quartz schist. Beresitization granite is also two rock ore bearing rock, gradient relation between molybdenum ore body and surrounding rock boundaries, molybdenum ore due to depth below 20m, molybdenum ore for primary ore, molybdenum sulfide in form. Ore type is primary molybdenum sulfide ore.
