胶东石英脉—蚀变岩型金矿床深部盲矿预测的构造叠加晕模型

Structure Superimposed Halo Model of Deep Blind Ore Forecast for the Quartz Vein-Altered Rock Type Gold Deposits in East Shandong Province

在研究胶东典型石英脉型、蚀变岩型金矿床深部盲矿预测构造叠加晕模型的基础上,总结其共性,建立了胶东石英脉型和蚀变岩型构造叠加晕理想模式,确定了盲矿预测的5条构造叠加晕准则。在研究预测中,先后对多个金矿进行跟踪研究,根据预测靶位见矿情况,总结不见矿靶位原因,修改完善预测模式和盲矿预测标志,并向矿床深部不断推进预测。构造叠加晕找盲矿法在理论和方法技术研究方面都取得了新的突破性进展,不仅完善和丰富了构造叠加晕找盲矿理论,方法技术不断完善和趋于成熟。应用各矿床构造叠加晕模式和盲矿预测标志对矿区深部进行预测,取得了显著的找矿效果。

Based on the study of typical quartz vein type and structural superimposed halo model of blind ore pre- diction in deep altered rock type gold deposits of Shandong Province,the summarize of its common,we built the ideal structure superimposed halo model of quartz vein and altered rock type,determined five guidelines of blind ore forecast structural superimposed halo.During the prediction,we conducted the follow-up study of multiple gold targets,summaried the reasons of not see mine targets according to projections,revised and improved the forecast- ing models and the predict sign of blind mine, the forecast was continuously pushed forward into deep deposit.The method of looking for blind ore by structural superimposed halo achieved a new breakthrough both in the theory and methods technical research,not only improved the theory of the method,but also made the techniques more mature.There was a significant prospecting effect by using the method to forecast blind mine in deep deposits.
