南岭 H 地区是我国著名的钨、锡、稀土、铌、钽、铀成矿区。通过剖折南岭 H 地区地质构造特征及地质发展史上几个重要事件对认识本成矿区的地质特点及花岗岩型铀矿时,空分布规律有一定启示。一、地质发展史上两条重要地质界线1、前加里东期(Z—S)该时期南岭 H 区以茶陵—郴州为界,东西二边沉积建造、构造环境宛然不一。西边震旦系假整合、局部角度不整合於板溪群之上,属地槽向地台过渡性沉积,一般可分两个统,下
Nanling H area is China’s famous tungsten, tin, rare earth, niobium, tantalum, uranium metallogenic area. Through the analysis of the geological structure of Nanling H area and several important events in the history of geological development, it is of some enlightenment to understand the geological characteristics and granitetype uranium deposits in this metallogenic area. I. Two Important Geological Ways in the History of Geological Formations 1. Pre-Caledonian Period (Z-S) During this period, the Nanling H area was deposited under the Chaling-Chenzhou bounded by the east and west sides and the tectonic environment varied. The Sinian system on the west is amalgamating and the partial angle does not conform to the Banxi group. It belongs to the transitional trough to the platform. Generally, it can be divided into two systems:
