吉林海沟金矿石英的红外光谱及热发光特征

THE CHARACTERICS OF QUARTZNINFKARED SPECTROMETRY AND THERMOLUMINECENCE IN HAIGOU GOLD DEPOSIT,JILIN PROVINCE

通过对海沟金矿床石英的红外光谱及热发光研究，获得如下认识：石英包体中Ｈ＿２Ｏ（Ａ＿１）和ＣＯ＿２（Ａ＿２）的相对吸光度可作为含矿性定量的评价指标，即Ａ１＜０．６和Ａ＿２＜０．１２含矿性差；０．６＜Ａ＿１＜ｌ．１和０．１２＜Ａ＿２＜ｌ．３５含矿性比较好Ａ＿１＞ｌ．１和人＞ｌ．３５含矿性好。石英的热发光曲线属双峰型舍矿性好，单峰型含矿性差或不含矿。同时用上述两种方法划分成矿阶段及确定矿体的埋藏深度也具有一定的实际意义。

By studying the infrared spectrometry and thermoluminescence of quartzfrom Haigou gold deposit,the relative degree of absorptivity of H_2O(A_1)and CO_2(A_2)inquartz inclusion can act as the quantitative pvaluation critera of ore potentiality.A_1<0.6and A_2<0.12 indicates a bad ore potentiality,while 0.6<A_l<l.l and 0.12<A_2<l.35represents a good one and the A_1.>1.1 and A_2>1.35 is better.When thethermoluminescence curve of quartz has double peaks,its ore potentiality is good. Singlepeak on curve indites a bad ore potentiality or ore-free. Using these two methodstogether,one can define the mineralization stages and the depth of ore body.
