辽宁省瓦房店金刚石原生矿找矿方法组合模型的建立

Combined model establishment for diamond primary ore prospecting method in Wafangdian of Liaoning Province

为了进一步扩大金刚石勘查成果,提交新增金刚石矿资源量,以辽宁省瓦房店地区金伯利岩型金刚石原生矿作为重点研究对象,总结归纳了应用地球物理、水系重砂、地球化学、遥感及三维地质等技术方法的找矿模型,建立了周期短且经济的3种找矿方法组合模型,即重砂法+地面高精度磁测+工程揭露(化探)找矿方法组岩模型、航空物探+地面高精度磁测+重砂法+工程揭露(化探)找矿方法组合模型以及遥感+重砂法+地面高精度磁测+化探+工程揭露找矿方法组合模型。研究成果可对辽宁省金刚石勘查工作起到指导意义。

In order to further expand the achievements of diamond exploration and submit newly added diamond resources,the authors in this paper take kimberlite-type diamond primary ore in Wafangdian of Liaoning Province as the key research object to summarize the prospecting model by applying geophysical,river system heavy sand,geochemical,remote sensing and three-dimensional geological methods.The combination model of three prospecting methods with short period and economy was established,including heavy sand method+high precision magnetic survey on the ground+engineering exposure(geochemical exploration),airborne geophysical prospecting+high-precision magnetic survey on the ground+heavy sand+engineering exposure(geochemical exploration),remote sensing+heavy sand+high precision magnetic survey on the ground+geochemical exploration+engineering exposure prospecting method.This work has important guiding significance for diamond exploration in Liaoning Province in the future.
