| 摘 要： | 研究表明，文峪金矿床无矿、贫金与矿体石英脉其热爆裂特征在起爆温度、爆裂温度范围、热爆曲线形态主爆峰值等方面均存在明为差异，可作为石英脉含矿性评价的重要标志。根据石英热爆裂参数，对５０５及５３０脉局部地段开展了填图研究。圈定了具不同类爆裂特征的石英分布范围，据此平价了其深部成矿远景，其结果对同类金矿床预测评价工作具有重要的方法学意义。

| Abstract: | The study showed that the barren quartz, poor goldbearing quartz and quartz from ore bodies possess obviously different thermal decrepitation features on beginning decrepitation temperature, decrepitation temperature region, shape of decrepitation curve as well as main decrepitation peak value etc.aspects, so they are important marks in evaluation of goldbearing features of quartz veins. According to the thermal decrepitation parameters of quartz, mapping of the given parts of vein No.505 and No.530 was carried out, the distribution of quartz with different thermal decrepitation characteristics was enclosed and their mineralization perspective of deeper level parts was evaluated. So the result of this study has great methodological significance for prognostic and evaluation work of the same type of gold deposits. |
