【摘要】 用甲玛矿床成功的勘查经验指导矿区下一步工作以及区域找矿。甲玛矿床经过详细的勘探与研究,已经成为冈底斯成矿带内最典型和最完整的斑岩型矿床系统。该系统包括了斑岩型钼矿体、夕卡岩型铜多金属矿体、角岩型钼(铜)矿体以及外围独立金矿体。文章以斑岩型钼矿、夕卡岩型钼矿以及角岩型钼矿为研究对象,进行了详细的地质特征描述。在地质研究的基础上,结合前人研究成果,对甲玛钼的来源及沉淀过程进行了简要分析,并在此基础上提出了甲玛斑岩矿床系统模型。文章还提出了运用斑岩矿床系统模型开展矿区及区域找矿评价的建议。更多还原

【Abstract】 The successful experiences in prospecting the Jiama deposit are used to guide the further work in prospecting the region.On the basis of the detailed prospecting and investigations,the Jiama deposit has been supposed to be the most typical and complete porphyry deposit system in the Gangdisi mineralization belt.This system includes the porphyry-type molybdenum,skarn-type copper-polymetal,hornfels-type molybdenum(copper)and peripheral self-golden ore-bodies.This paper studies the porphyry-type molybdenum,skarn-type copper-polymetal and hornfels-type molybdenum ore-bodies and describes their geological features in detail.And,combined with the geological studies and the previous research results,the paper makes a brief analysis of the origin and deposition process of Jiama molybdenum.Further,it proposes a system model of the Jiama porphyry deposit and recommendes it as a method to assess the regional prospecting.更多还原
