The Brazil Lake pegmatite of southwestern Nova Scotia is a rare example of Li-Cs-Ta (LCT) -type pegmatite in the Meguma terrane of Nova Scotia. This spodumene-rich pegmatite is hosted by metasedimentary and metavolcanic rocks of the Silurian White Rock Formation, which records both Acadian and Alleghanian deformation. In order to constrain the petrogenesis and thermal history of the pegmatite, samples of tantalite, molybdenite, and muscovite were collected for U-Pb, Re-Os, and 40Ar/39Ar dating, respectively. A single, large, euhedral tantalite crystal from an albite-quartz-spodumene assemblage yielded concordant U-Pb ages between 365 and 395 Ma (all ± 1– 2 Ma). In contrast, molybdenite from quartzite adjacent to the pegmatite gave a Re-Os a...
