Abstract
Taoyuan area is located in the south of the Cathaysia block,the eastern section of the the Nanling Mountain structural belt,the western edge of Changtang Basin,and the eastern part of the dam rock mass.In terms of tectonic location,it is located near the junction zone of the Gangrou Block between the Fujian-Jiangxi Post Caledonian Uplift and the Hunan-Guangxi-North Guangdong Haixi-Indochina Depression.The uranium mineralization in the area is well-developed and has favorable geological conditions for uranium mineralization.By analyzing the elemental geochemical characteristics of the granite in the Taoyuan area,it is believed that the granite in the Taoyuan area belongs to the A1 subclass of A-type granite,which is sub alkaline,rich in Si,poor in Sr,Eu,Ba,P,Ti,and has high Ga/Al and TFe/Mg values.It was formed in a extensional tectonic environment during the late Yanshan orogeny.关键词
