南岭6812花岗岩是我国黄钇钽矿的唯一产地。中国科学院地球化学研究所和武汉地质学院曾先后对该矿物进行了详细的研究。本文着重讨论含矿花岗岩的地质特征及黄钇钽矿的成因。 一、黄钇钽矿的产出特征 黄钇钽矿赋存于构造复杂、经纬向挤压带十分发育、沿断裂带有多次岩浆侵入的地区。而含矿岩体产于某花岗岩体的外带。矿体呈岩墙群侵入于震旦系地层中。矿体上盘常有几公分的似伟晶岩复盖。用钾-
Nanling 6812 granite is our country yttrium tantalum ore only origin. The Institute of Geochemistry, Chinese Academy of Sciences and the Wuhan Institute of Geology have carried out a detailed study of the mineral. This article focuses on the geological characteristics of ore-bearing granite and the genesis of Yttrium-tantalum ore. First, the yttrium tantalum ore output characteristics Yttrium tantalum ore hosted in the complex structure, latitude and longitude to the extrusion zone is very developed along the fault zone with multiple magma intrusion. The ore-bearing rock mass produced in a granite belt. The ore body is intrusion into the Sinian strata. Ore plate often several cents like pegmatite cover. With potassium -
