山东玲珑金矿田51号脉成矿规律研究及远景预测

为了解决危机矿山资源问题，对玲珑金矿田51号脉的脉岩特性进行了细致研究，从而对矿脉深部成矿特征及成矿规律有了进一步的认识。运用脉岩的特性，发现在深部成矿条件下51号脉被后期形成的煌斑岩错断、穿插、位移且平行共生，达到了依脉岩找矿的良好效果。结合生产实践，对符合低品位开发利用的51号脉进行综合价值分析和成矿靶区预测，认为其品位虽然较低，但仍然具有较大的开采利用价值，从而扩大了远景地质储量和生产服务年限，缓解了生产接续困难的问题。

Sduty on Metallogenic Regularity and Prospecting of No.51 Vein in Linglong Gold Mine Field, Shandong Province

In order to solve the crisis of mines resources,characteristics of No. 51 vein in Linglong gold mine field are carefully researched, and obtain better understant about vein metallogenic features and ore-forming regularity in the deep.Using the characteristics of vein rocks, we find that the No. 51 vein is broken, dislocated, interspersed, displaced and parallel intergrowth by lamprophyre in the later period in deep metallogenic conditions,getting good effect in vein rocks prospecting.Combining with the examples of production practice ,the comprehensive utilization value is analysised,metallogenic target areas are forecasted in Vein No. 51,we suggest that the Vein No. 51 is still with large mining use value.Thus, the vision of geological reserves, production and service life of mine are expand- ed, problems of the continuation production are resolved.
