摘要
对产于烟台金斗山金矿内的贯通性非金属矿物石英及碳酸盐类的化学成分、晶体习性、流体包裹体和天然热发光特征做了研究 ,结果表明 ,矿床的主成矿阶段的环境介质为酸性偏中性 ,富矿和贫矿石英的热发光曲线均为双峰型 ,但峰点温度、总积分强度有显著差异。碳酸盐类矿物的总体演化趋势为从富镁铁向富钙方向演化 ,碳酸盐热发光曲线的峰型和积分强度是判别成矿期和非成矿期碳酸盐的可信参数。
The chemical composition, crystal morphology, fluid inclusions and thermoluminescent characteristics of non-metallic minerals such as quartz and carbonate from the Jindoushan gold deposit were studied in detail. The crystal habit of quartz implied the acidic media at the main mineralization stage. The thermoluminescent curves of quartz and carbonate and their integral intensity are reliable indicators for distinguishing quartz and carbonate of different mineralizing stages.
