原始语种摘要: Abstract(#br)The diopside-allanite veins and apatite breccia veins of the Hoidas Lake LREE deposit cross-cut the deformed Archaean and Paleoproterozoic granitoid gneisses of the Rae Subprovince, in northern Saskatchewan, Canada. The timing and source of this unusual and complex REE deposit are not well-constrained. Here we report on the results of LA-ICP-MS U-Pb geochronology of zircon and titanite from diopside-allanite veins and green apatite and monazite from apatite breccia veins, Hf isotopic data for zircon, and Sm-Nd isotopic data for titanite, apatite and monazite, in an attempt to constrain the age and duration of crystallization of REE-bearing phases, and provide implications on the source of the mineralization. Geological relationships and in situ U-Pb data indicate that the REE...
