新疆金窝子金矿床4号含金石英脉矿化特征及深部找矿前景探讨

Discussion on the mineralization characteristics and deep prospecting potential of No.4 auriferous quartz vein of the Jinwozi gold deposit in Xinjiang

金窝子金矿床是新疆东部最为重要的金矿床之一。对矿床内4号含金石英脉地质特征及矿化特征作了详细的研究。矿石品位、含金石英脉厚度及矿化强度变化趋势分析表明,金矿化在含金石英脉内具有分段富集的特点,且含金石英脉在中部和北部矿化较好。黄铁矿热电性特征研究得出,含金石英脉内黄铁矿导型以P型为主,热电系数沿垂向变化较小,反映4号含金石英脉产出稳定,具有深延的特点。研究表明,4号含金石英脉已揭露部分位于整个含金石英脉的浅部,深部应具有较好的找矿前景。

Jinwozi gold deposit is one of the most important gold deposits in eastern Xinjiang. The paper studies the geological features and mineralization characteristics of the No. 4 auriferous quartz vein in detail. Comprehensive analysis on the trend of the grade, thickness and mineralization level reveals that the mineralization is a segmentation enrichment one and more better in the middle and northern part of the known quartz vein. It is revealed that the thermoelectricity of pyrite is mainly P-type and the thermoelectrical coefficient varies smally on the vertical direction, which indicates the auriferous quartz vein appears stablely with deep extension. The study results show that the exposed vein is only the upper part with a well prospecting potential at depth.
