Dec 07, 2005 (A Wilson) - The complex intrudes Archean rocks of the Wawa subprovince and has been emplaced along faults associated with the Kapuskasing Structural Zone. The complex consists of sovite, silicocarbonatite, ijolite and feruginous rauhaugite. The complex is zoned with sovite and silicocarbonatite at the periphery and rauhaugite in the core. Ijolite occurs as blocks metasomatized by fenitizing fluids in the sovite rim of the complex. Lamprophyr dikes with associated iron carbonate and sodium amphibole alteration are common in the area near the complex.

Dec 07, 2005 (A Wilson) - Outcrops are scarce in the area. Some of the sovite contains porphyritic rhombs of carbonate up to 10 cm set in a fine-grained matrix. Apatite, clinopyroxene (dioside and Na-bearing), magnetite, biotite and Na-bearing amphibole are present as accessory minerals to the dolomite, ankerite and calcite.

Dec 07, 2005 (A Wilson) - Small, well-formed pyrochlore octahedra occur in the disintegrated calcite carbonatite exposure. Surface samples returned Nb values up to 0.52% Nb2O5.
