Phase 2 Initial Borehole Drilling and Testing, Ignace Area. Thin Section Petrography and Lithogeoche

The grain size of the quartz is inequigranular, and some of the crystals are recrystallized into smaller interlobate crystals near to contact with the host rock and the alkali feldspar. [...] Some of the alteration products define subhedral to euhedral shapes within the plagioclase, thus indicating that the growth zoning occurred during the magmatic growth of the plagioclase, and that the core of the crystals are richer in anorthite. [...] white mica tr Rare and fine-grained lamellae of white mica up to 0.2 overprinted some of the biotite crystals, and in these instances, the boundary between the white mica and the biotite are populated by very fine- to fine-grained crystals of titanite. [...] epidote 1.5 ‒ 2 Anhedral crystals of epidote up to 0.8 long overprinted the core of the plagioclase and are dispersed within the quartz and the biotite. [...] carbonate tr Rare and anhedral crystals of carbonate are up to 0.3 dispersed within the biotite and along the interstices between the biotite and the epidote.
