| sample_remark | -[informal_name: Suite #2]- Jagodzinski, 2005: Sample is an intensely foliated megacrystic granodiorite. This sample has abundant augen of largely sericitised plagioclase and less abundant microcline to 4 mm long, with aggregates of epidote in some augen of plagioclase and microcline. The groundmass is laminated with quartz-rich lamellae, feldspathic or quartzofeldspathic lamellae and micaceous lamellae mostly less than 3 mm wide. The quartz is all recrystallised but has some lenses with low-angle grain-boundaries suggesting old-grain control. The feldspar within the groundmass includes sericitised plagioclase as well as less abundant microcline. Abundant schistose biotite has been totally altered to chlorite and leucoxene, but schistose sericite is also common. Rare opaque grains occur, mostly in epidote, and there is accessory apatite as well as zircon to 0.1 mm in grainsize. The mineralogy indicates a gneissic granodiorite. The sample was taken from diamond drillhole BHD1, depth interval 283.6- 284, 285.5-285.7, 286.5-286.9, 290.5-291, 296.7-298.2, 321.8-322.2 m. |
