英文摘要: Abstract(#br)Southeast China with its widespread occurrences of Mesozoic igneous rocks, is one of the largest magmatic provinces worldwide, containing a large variety of mineral types, including hypothermal W-Sn, porphyry Cu, epithermal Au deposits. The Gudongkeng deposit is an example consisting of fluorite mineralisation trending SE over a distance of about 6 km. The major minerals in the deposit include fluorite and calcite of a hydrothermal origin and interpreted as a vein-type deposit associated with the Linghou Granite that yields a zircon U–Pb date of 100 ± 1 Ma, but intriguingly the fluorite yields an Sm–Nd isochron age of 73 ± 3 Ma, placing the genesis of the fluorite as a post-magmatic event. Fluid inclusions in the fluorite have low homogenisation temperatures of 104–195° C,...
