Inclusions of Vein Quartz Ore in Xingtai Area of Hebei Province
摘要
Abstract
High quality vein quartz ore in Xingtai area of Hebei Province was studied .The fluid inclusions in quartz were analyzed by petrography , temperature measurement and composition analysis on the basis of optical microscopy and chemical composition .The results show that the content of SiO 2 in the quartz is as high as 99 .979%, and the fluid inclusions can be generally observed in the quartz grains , mainly in the state of gas-liquid two phases , and a small amount of gas , liquid and three-phase inclusions .Raman analysis show that the gas and liquid components are CO 2 , H2 O.The results show that the homogeneous temperature is 143-247 ℃, the average temperature is 196 ℃, the solubility of the neutron inclusions in three-phase inclusions is 160-180 ℃, and the corresponding mineral is nesquehonite .The ore-forming fluids of the quartz ore are considered to be medium-low temperature hydrothermal fluids .关键词
