摘要
河北大西沟金矿石英热释光与黄铁矿热电性特征研究表明,随着成矿阶段的演化,石英热释光曲线的峰形由复杂趋于简单,发光强度经历了一个先升高再降低的过程。黄铁矿热电性以N型为主,热电系数α值相对集中,离散范围小。通过石英热释光特征与黄铁矿热电性标型特征分析,结合成矿地质规律研究,对大西沟金矿床矿化远景提出了科学的评价,并指明了找矿方向。
Results from the research on the characteristics of heat release light of quartz and pyrite typomorph from Daxigou gold deposit show the change of the heat release peak from complex to simple and light emination from temperature rise to drop. Thermoelectric property is dominated by N type with relative concentration of the thermoelectric coeficent values and the narrow discrete range. Combined with metallogenic and geological regularity research ore prospect of Daxigou gold deposit is scientifically evaluated on basis of the research on the heat release light and the typomorphic characteristics and the oresearching direction pointed out.
