摘要
内蒙古巴尔哲碱性花岗岩稀有稀土特大型矿床是国内首次发现的一种新类型工业矿床,其规模居亚洲第三位.含矿岩体为燕山期碱性花岗岩,岩体普遍矿化,岩体即是矿体,矿石品位富,稀有稀土元素种类多,其共生伴生矿物多达44种,工业矿物以羟硅铍钇铈矿、烧绿石、铌铁矿、锌日光榴石为主.
The special large sized alkali granite rare metal and rare-earth ores in Baerze of Nei Mongol is the new industrial type ore deposit first discovered in China with the scale in third place in Asian. The ore-bearing magmatic body is a Yanshanian alkali granite and the rock body is wholly mineralized and become ore body rich in ore grade. Rare rnetal and rare earth elements are many and varied. The paragenetic and associated minerals in ore are more than 44 species. The major economic minerals are hydroxyl-Si-Be-Y -Se mineral,pyrochlore,niobite and genthelvite.
