Province: Grenville
Subprovince: Central Metasedimentary Belt
Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - The oldest rocks in the area are mafic to intermediate metavolcanics and mafic to felsic gneisses and anatectites (high grade equivalent). The metasediments are largely carbonate metasediments (predominantly calcitic), and clastic siliceous gneisses (quartzose wacke to feldspathic wacke). Hornblende-rich gneisses become prevalent to the east in the Clare River Synform. Carbonate metasediments occur along the western periphery and as large xenoliths within the Mountain Grove intrusion. The Robertson Lake mylonite zone (striking 045 degrees and dipping 30 to 50 degrees south), passes through the village of Mountain Grove structurally subdividing the area into two strikingly different zones. The shear zone extends 80 km and typically ranges from 0.5 to 1.0 km in width. West of the shear zone rocks exhibit two periods of deformation and possibly a third whereas the structural geometry east of the shear zone becomes one of domal intrusions withing the intra-limb zone of a broad synform plunging shallowly eastwards. (Wolfe 1982) The intrusives east of the shear zone are late tectonic and consist of the Mountain Grove Mafic Intrusive and the McLean Granitic Pluton. The Mountain Grove Intrusion is the oldest and is compositionally a well-layered gabbro-anorthosite-syenite body. The McLean Granite Pluton is intrusive to the Mountain Grove Intrusion and ranges in composition from trondhjemite to granite with minor syenitic phases and is generally massive.

Sep 10, 2013 (A Wilson) - Graphite is found in an outcrop of fine to medium grained laminated calcitic marble. The layers range in width from 0.5 to 2 cm, although there are also some bands of coarse-grained calcitic marble that are > 2 cm in width. The carbonate unit is intruded by both the Mountain Grove mafic intrusion and the pegmatitic phases of the McLean granitic pluton.

Sep 10, 2013 (D Laidlaw) - An analysed grab sample yielded, Zn 48.3% , Pb 0.55% and Cu 198 ppm, (Geosciences Laboratories, OGS, Toronto). Two small (0.25 m maximum dimension) concentrations of massive sphalerite and pyrite were found near an abandoned shack on the Hawley Property.
