    甘肃省银矿成矿规律与资源潜力分析

    Metallogenic regularity and potential analysis of silver deposits in Gansu Province

    • 摘要:
      研究目的 本文通过系统研究甘肃银矿资源特征和成矿规律,为找矿预测和进一步勘查部署提供理论依据。
      研究方法 在对甘肃银矿资源特征和成矿规律研究的基础上,确定了各类型银矿的预测模型,并利用地质参数体积法在MORPAS 3.0资源评价系统平台上估算了甘肃银矿的潜在资源量,进而对其资源潜力进行分析。
      研究结果 甘肃银矿资源量有望增加3倍以上;热液型、岩浆熔离型、VMS型和SEDEX型是甘肃银矿的主要矿床类型,也是未来找矿的主攻类型。
      结论 根据预测结果,甘肃银矿资源量主要集中于北山、祁连、龙首山和西秦岭地区,建议在南泉、石洞沟、赛日欠、柳稍沟这4个地区设立重点勘查部署区,在南金山、花牛山、龙首山、白银厂、蛟龙掌、代家庄、厂坝—邓家山、洛坝、毕家山等地区铜、铅锌、金矿勘查中要特别留意伴生银矿的评价工作。

       

      Abstract:
      This paper is the result of mineral exploration engineering.
      Objective This paper systematically studies the characteristics and on metallogenic regularity of silver mineral resources in Gansu Province, providing a theoretical support for prospecting prediction and further exploration deployment.
      Methods Based on the research on metallogenic characteristics of silver mine in Gansu province, prediction models of distinguished types of silver mine are determined. Meanwhile, the potential silver resources are estimated through geological parameter volume methodology in MORPAS 3.0 system, the potential resources thus are analysed.
      Results The silver resources in Gansu province is expected to increase by above 3 times. Hydrothermal, megma dissociation, VMS and SEDEX types are staple types of silver mineral in Gansu province and crucial types in future work.
      Conclusions According to the predicting result, silver resources in Gansu province mainly exists in Beishan, Qilian, Longshoushan and western Qinling area. This assay suggests that prospecting deployment emphasis should be settled in Nanquan, Shidonggou, Sairiqian, Liushaogou area, meanwhile, evaluating works on associated silver minerals should be extraordinarily focused on during copper, lead-zinc, gold exploration in Nanjinshan, Huaniushan, Longshoushan, Baiyinchang, Jiaolongzhang, Daijiazhuang, Changba−Dengjiashan, Luoba, Bijiashan area etc.
