Geological characteristics and genetic analysis of the iron-bearing tourmalitedikes in Bangnong area, Xaitongmoin County, Tibet
摘要
Abstract
This paper describes geological characteristics of the iron-bearing tourmalite dikes in Bangnong area, Xaitongmoin County, Tibet. The iron-bearing tourmalite dikes extend roughly parallel to the fault. The wall rock is medium-grained porphyritic hornblende biotite monzogranite. The tourmalite dikes have experienced different degrees of iron mineralization. Statistics reveal 23 promising mineralized veins. Ore minerals include hematite(specularite), whereas gangue minerals are quartz, tourmaline, and a small amount of muscovite and feldspar. Ores are of scaly and flaky textures and massive structure. Ore types include massive form, dissemination and veinlets. Oxygen isotope analysis shows that the average of δ 18Ov-smow from 5 samples is 6.8‰. Oxygen and hydrogen isotopic analysis of the fluid indicates that the ore-forming fluids were dominated by meteoric water, with the probable participation of magmatic water.关键词
