| 摘 要： | 黄沙坪矿田的综合找矿模式可概括为已知黄沙坪铅锌矿床成矿模式、地质地球化学及地球物理找矿标志以及最优找矿方法。黄沙坪铅锌矿床成矿母岩与中酸性高侵位岩体有关,倒转背斜轴部及其纵横断裂交汇处控制矿床,走向逆冲断裂带、间层断裂或虚脱带、岩体侵入接触带等控制矿体;矿床范围内有重力、磁力、电性、放射性等异常,出现成矿元素及重矿物指示标志;探查岩体(探岩)、圈定远景区(圈区)找矿床赋存部位(找位)、寻工业矿体(寻体)是最优找矿方法。此综合找矿模式在隐伏矿床预测中的应用经钻探验证取得了积极效果。

| Abstract: | The comprehensive prospecting model includes the metallogenic model, geologic and geochemical as well as geophysical prospecting criteria, and optimal prospecting methodo-logy of the known Huangshaping lead-zinc ore deposit. Huangshaping lead-zinc deposit is related to the medium acidic high-level intrusives; the axial position of the reversed anticlines and the intersecting position of varing directional faults controlling the depo-sits; the strike thrust faults zone, the interlayer fractures or the unocoupaied space, and the contacting zone of rock bodies controlling the ore bodies; there being gravitational, magnetic, electric and radioactive anomalies and indications of ore-forming elements and heavy minerals within the scope of the deposit; the optimal prospecting procedure inclu-ding detecting hidden rock bodies, outlining target areas, looking for hosting positions of deposits and locating economic orebodies. This comprehensive prospecting model has been applied to the prognosis of concealed ore deposits and positive results are obtained through verification by drilling. |
