摘要:

新房金矿床是近年新发现的中型金矿床,矿体主要赋存于新房变质核杂岩的盖层与基底之间的韧性剪切带内,严格受伸展拆离带控制,矿石类型以蚀变岩型为主,石英脉型次之。该矿床目前正在勘探中,深部及外围成矿潜力巨大。通过地质构造调查、地球物理勘查、地球化学勘查和钻探工程等多种三维立体手段,首次建立了新房金矿床三维地质构造模型,并通过地层、岩浆岩、构造与矿体之间的三维空间关系和成矿机制分析,研究成矿规律,建立了三维成矿预测模型,以期对下一步深部勘查提供科学指导。

Abstract:

The Xinfang Gold Deposit is a recently discovered medium-sized gold deposit,and the ore body mainly occurs within the ductile shear zone between the cover and basement of the Xinfang metamorphic core complex.It is strictly controlled by extensional detachment zones,with the predominant ore type being altered rock and the secondary quartz vein type.The deposit is currently being explored,and it has great potential for deep and peripheral mineralization.Through geological structural surveys,geophysical exploration,geochemical exploration,and drilling engineering,a three-dimensional geological structure model of the Xinfang Gold Deposit has been established for the first time.Through analysis of the three-dimensional spatial relationship between strata,magmatic rocks,structures,and ore bodies,as well as the study of mineralization laws,a 3D mineralization prediction model have been established,to provide scientific guidance for deep exploration in the next step.
