Notes
- Deep erosion has exposed much of the crater floor and only remnants of the melt sheet remain. Isolated patches of fill and subfloor target rocks are preserved (Taylor and Dence, 1969).
- Structure is defined by a ring of low hills 28 km in diameter (Grieve et al., 1988). Initial diameter estimate was 26 km (Taylor and Dence, 1969).
- A ring of low hills, 26 km in diameter, surrounds a depression, the centre of which is filled by Lake Mistastin. A horseshoe-shaped island (130 m above the lake level and 15 km in diameter) occupies the centre (Taylor and Dence, 1969). Horseshoe Island in the centre of Mistastin Lake appears to have very little erosion consistent with an estimate of 10 to 100 m erosion of melt rocks in the inner rim region of the structure (Marion, 2009). This suggests that the island is an original topographic high. Most of the island is shocked target rocks with one small outcrop of impact melt rocks, interpreted as a veneer (Singleton et al., 2011).
- Projectile may have been of iron composition (Wolf et al., 1980).
- Shocked zircon (FRIGN zircon, reidite) Tolometti et al. (2022)
- Shatter cones are poorly developed (Taylor and Dence, 1969). Presence of shatter cones in anorthosite is reported by (Marion and Sylvester, 2010). Shatter cones are poorly developed (Grieve, 2006).
- PDF in quartz and feldspars (Taylor and Dence, 1969). "On the mainland, basement rocks display lower levels of recorded shock with planar deformation features in quartz" (Grieve, 2006).
- The basement rocks of the central island are shocked, with the development of makelynite and diaplectic quartz glass" (Grieve, 2006).
- (Grieve, 1975) (McCormick et al., 1989) (Grieve and Cintala, 1992) (Marion & Sylvester, 2010) (Hervé et al., 2015) (Pickersgill et al., 2015b) (Hill et al., 2020) (Mader and Osinski, 2018) reinterpreted melt-free to -poor polymict impact breccias overlain by impact melt-bearing breccias and/or melt rocks located within the rim of the original crater, but outside the initial transient cavity as proximal ejecta deposits.
