New Isotopic Approaches to Hydrothermal Ore Deposits

这项研究将强调同位素、化学和流体包裹体研究的整合，相对较新的技术和方法包括：(1)萤石、锡石、石榴石等矿物的Sm-Nd和U-Pb定年；(2)高分辨率U-Pb和40Ar-39Ar的年代学研究，探讨了岩体冷却史与相关热液活动年龄和温度之间的关系；(3)流体包裹体的Rb-Sr和40Ar-39定年研究；H、N、Ar、S、C)和稀土元素对单个矿物及其流体包裹体成分来源的研究。英国两个经典热液矿化区。寇努比亚成矿省的Ns-W-As-Cu成矿作用。二是北奔宁矿田与mvt相关的萤石-重晶石基金属矿床。

This research will emphasize integration of isotopic, chemical and fluid inclusion studies, the relatively new techniques and approaches to include: (1) Sm-Nd and U-Pb dating of minerals such as fluorite, cassiterite and garnet, (2) high resolution U-Pb and 40Ar-39Ar geochronological studies of the relationship between the cooling history of pluton, and the age and temperature of associated hydrothermal activity, (3) Rb-Sr and 40Ar-39 dating studies of fluid inclusions, and (4) multi-isotopic (Nd,Sr,Pb,O, H,N,Ar,S,C) and rare earth element studies of the sources of components in individual minerals and their fluid inclusions. Two areas of classical hydrothermal mineralization in the United Kingdom. The Ns-W-As-Cu mineralization of the Cornubian metallogenic province. The second is the MVT-related fluorite- barite-base metal deposits of the North Pennine Orefield.
