赣中地区若干金矿床(点)石英热发光特征及地质意义

The Features and Geological Significance of Thermo luminescence of Quartz in Some Gold Deposits in Ganzhong Area in Jiangxi Province

本文描述了赣中地区若干金矿床石英热发光特征，分析了其与金含量及化学成分之间的关系。该区石英热发光曲线主要有双峰、单峰和隐峰（双向曲线）三种。研究表明，双峰和单峰者金矿化较好；隐峰者，金含量较低。石英热发光的陷阱深度与金品位呈正消长关系。上述研究，有助于该区金矿的找矿和矿床评价工作。

The features of thermoluminescence of quartz in gold ore are described, and its relations to gold mineralization and composition of quartz are analyzed. There are three kinds of quartz thermoluminescence curves in this area they are two peak,one peak and hide peak(two directions curve). The study indicates that the gold ores with the two peaks and the one peaks quartz thermoluminescence curves are generally rich in gold, but the hide peaks are barren. The correlation between the trap depth(E) of thermoluminescence of quartz and Au grade is positive. The study contributed to protesting and evalution of gold deposits in this area.
