Natural Features

Thackery Provincial Nature Reserve protects a significant sequence of Archean metavolcanic rocks of the Kenojevis Group. These rocks lie within the central portion of the Abitibi subprovince of the Canadian Shield. The outcrop provides an unusually clear view of several hundred metres of tholeiitic basalt of varying composition and textures. Composition varies from grey-to-green magnesium rich tholeiite basalt, to black-to-dark green iron rich basalt. Textures exhibit fine grained, massive, pillowed and pillowed-breccia flows to thin fragmental glass tuffs, and other distinct zones.
