摘要: 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。Abstract: 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 Pro-vince 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.
