摘要
经过对黄石板铅锌矿含矿层展布、产态、矿化富集规律等基本特征的总结,以及对含矿层中典型热水沉积岩岩石学特征、岩石化学特征、含矿物质来源初步分析,通过热水沉积岩和盆地正常水沉积围岩的稀土元素地球化学等与南秦岭泥盆纪热水沉积岩的对比、研究,初步认为白河县黄石板铅锌矿为一较典型的热水沉积矿床。提出黄石板矿区西段高家沟一带深部仍存在隐伏矿体的可能性较大,并通过钻探验证发现较富隐伏铅锌矿体。运用热水沉积成岩成矿理论指出该地区找矿方向。
The characteristics of the distribution, attitude and enrichment of lead-zinc beds, hydrothermal sedimentary features, petrochemistry and the sources of ore-bearing materials, comparison between hydrothermal sediments and rare-earth elements from normal-water sedimentary wall-rocks in basin and the Devonian hydrothermal sediments in the southern Qinling, demonstrate the Huangshiban lead-zinc deposit in Baihe county is a typical hydrotherreal sedimentary deposit. Drilling has found some blind enrichment lead-zinc ore bodies. Therefore, it would be very possible that blind ore bodies did occur in depth of Gaojiagou area in the western portion of the Huangshiban mineralized area. The metallogeny theory of hydrothermal sedimentation guides the direction for further ore-prospecting.
