Analysis on Metallogenic Conditions and Geological Features of Uranium Anomaly in Nanmulin Basin,Tibet
摘要
Abstract
Nanmulin basin is a Meso-Cenozoic fault basin that experienced multi-stage tectonic activities in Tibet.In recent years,multiple abnormal points (belt)was discovered subsequently in the basin.Uranium mineralization mainly occurs in Tertiary rhyolite, tuff and Himalayan stage granite rocks, etc.High content uranium was widely distributed in the rocks of basement,covers and source area which provide the material foundation for uranium mineralization.Structure are well developed and a lot of uranium anomalies widely distribute in the central and eastern fracture zones which can be regarded as the focal ar-ea for the prospecting. Nanmulin basin was believed with favorable geology conditions and good prospec-ting for the formation of structure-hydrothermal uranium deposit of granite type,volcanic type.关键词
