通过对小西南岔金矿床石英的红外光谱及热发光研究表明:石英包体片中H_2O(A_1)和CO_2(A_2)的相对吸光度可作为含矿性的定量评价指标,即A_1<1.0和A_2<0.12含矿性差;1.02.5和A_2>0.16含矿性好。石英的热发光曲线属双峰型者含矿性好,单峰型者含矿性差。
The infrared spectroscopy and thermoluminescence of Quartz in Xiaoxi Nancha gold deposit show that the relative absorbance of H_2O (A_1) and CO_2 (A_2) in quartz inclusions can be used as a quantitative evaluation index of ore - bearing, ie A_1 <1.0 and A_2 <0.12 with poor oreability; 1.0 2.5 and A_2> 0.16 with good oreability. Quartz’s heat-emitting curve is a bimodal type containing ore is good, unimodal type containing poor.
