文峪金矿床矿物石英红外吸收光谱、热发光、热爆温度等研究表明,含矿与无矿石英上述特征具明显差异:①含矿石英红外吸收光谱H2O吸收峰强,光密度D1>D2,D2/D1<1,无矿石英红外吸收光谱H2O吸收峰弱,光密度D1<D2,D2/D1>1;②含矿石英热发光强度低,峰强低于150cps,总发光强度低于10000cps;无矿石英热发光强度高,峰强高于150cps,总发光强度大于10000cps;③含矿石英热爆频温度低,一般为140~180℃;无矿石英热爆频温度高,一般为420~460℃。为该区金矿脉合矿性评价提供了重要标志。
Quartz infrared absorption spectroscopy, thermoluminescence and thermal explosion temperature of Wenyu gold deposit show that the above characteristics of ore-bearing and ore-free quartz are obviously different: (1) The absorption peak of H2O in ore-bearing quartz is strong, the optical density is D1> D2, D2 / D1 is less than 1, the infrared absorption spectrum of mineral infrared absorption spectrum of H2O is weak, the optical density is D1 1; (2) the ore containing quartz has low luminescence intensity, peak intensity below 150cps and total luminescence intensity below 10000cps ; Ore-free quartz thermal emission intensity is high, the peak intensity is higher than 150cps, the total luminous intensity is greater than 10000cps; ③ ore containing quartz thermal burst frequency is low, generally 140 ~ 180 ℃; ore-free quartz thermal burst frequency is high, usually 420 ~ 460 ℃. It provides an important symbol for the mineral evaluation of gold deposits in the area.
