Determination of Metallogenic Temperature of Fine Disseminated Gold Deposits by Way of Infrared Spectroscopic Method |
The metallogenic temperature of Jinya gold deposit in Guangxi province has been analysed by way of infrared spectroscopic method in the paper, which is 255-300℃.It has a narrower temperature range than that measured by inclusion homogenization method. In the disscussed method, only small amount of samples (0. 2-0. 5mg kerogen ) are needed. Taking Jinya gold deposit in Guangxi as an example, another effective way of determining the metellogenic temperature of fine disseminated gold dePOsits is disscussed, which is confirmed by the Rock-Eval analyses and the elastic vitrinite reflectance measurment.This method has a practical significance if it is used to determine palaeogeotherm in the marine and pre-Devonian strata which are lacking in vitrinite. |
