Lithology

Lithology Comments

Aug 13, 2020 (Bill Paterson) - Breaks et al. (2001) observed that beryl crystals occur sporadically in quartz-rich patches with increased tourmaline abundance in tourmaline-muscovite pegmatitic leucogranite.

Mineralization

Mineralization Comments

Aug 13, 2020 (Therese Pettigrew) - The occurrence on the eastern shoreline of Curie Lake is a single 5 cm diameter light green crystal in a quartz-rich patch within a tourmaline-rich pegmatitic leucogranite. Sample 01-FWB-17 from the biotite granite returned an assay of 85 ppm Li (Breaks et al., 2001). Tourmaline-muscovite pegmatitic leucogranite at Curie Lake contains relatively abundant black tourmaline (5 volume %) that is gradational into medium- to coarse-grained biotite granite. The tourmaline also occurs in quartz-rich patches where it is associated with rare pale green beryl. The most evolved tourmaline from the Allison Lake batholith is hosted by the potassic pegmatite at Curie Lake (locality 01-FWB-17-03). This is the only tourmaline in the batholith that has not interacted with the surrounding metasedimentary host rocks. This fine-grained, black tourmaline is schorl with almost no magnesium, elevated manganese content (0.3-1.4 weight % MnO) and moderate estimated lithium content (<0.4 weight % Li2O). (Breaks et al., 2003).
