Province: Grenville
Subprovince: Central Metasedimentary Belt
Geological Age: Mesoproterozoic
May 30, 2008 (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.

Geologist: C Papertzian
Notes: The Hawley wollastonite deposit was visited in late October 2002, along with two representatives of Highwood Resources who were interested in obtaining a bulk sample from this property. The farm where the deposit is located has not seen any development work in the past few years. The wollastonite occurs as white to beige, fine-to coarse-grained short prismatic to bladed crystals, typically 1-3 mm in length. The mineralized zone has been traced along strike 200 m and ranges in width from 15 to 50 m. The grade varies from 20 to 45%, averaging 30 to 35%. The unit is gradational to coarse-grained white calcitic marble. Small apatite rystals (<0.5 mm) occur as inclusions within and intergrown with calcite. The wollastonite lenses/layers are brownish at the edges where in contact with the calcite layers.
