陕西省西乡县猫儿寨铌钽矿化地质特征及成因分析
Geological Characteristics and Genetic Analysis of Niobium-Tantalum Mineralization in Mao'erzhai,Xixiang County,Shaanxi Province
摘要
Abstract
In this paper,based on geological surveys in the mining area and previous mineral exploration achievements in the region,a new niobium ore occurrence was discovered,and three niobium-tantalum ore bodies as well as six niobium-tantalum mineralized bodies were delineated.The ore-bearing geological bodies are alkaline dikes,within which the ore-bearing rock is alkaline syenite porphyry;the ore-controlling structure is a northwest-trending fault.The ore minerals include niobium-iron ore,yttrium-niobium ore,and heavy tantalum-iron ore.The gangue minerals are mainly orthoclase and microcline,with minor plagioclase,biotite,sericite,and quartz.The accessory minerals are titanite and apatite.The deposit is genetically classified as a magmatic hydrothermal type.Alkaline dikes are widely distributed and numerous in the area,indicating that the prospecting potential for alkaline rock-type niobium-tantalum ore is high.关键词
