چکیده انگلیسی
The recognition of the change in the rate of emplacement of volcanic units and particularly the change in chemistry of volcanic rocks, are critical exploration lithologic guides to use in the absence of chemical sediment deposits (exhalites). Although crustal extension and basin subsidence were factors in the shaping of the succession, their effects were too subtle to use as an exploration tool. A corollary of the recognition of a Member-level VHMS-bearing interval in the Teutonic Bore volcanic complex is that, like the Kidd-Munro assemblage stratigraphy (Abitibi GB), where several ore-bearing depositional breaks are known below the great Kidd Creek deposit, there is scope for the discovery of further (potentially larger) deposits on higher Formation or Group-level breaks in the TBVC.
