Feb 16, 2011 (J Bongfelt) - 'The area was mapped by J.C. Davies (1973) in Geological Report 111. The area is underlain by rocks of the Kakagi-Rowan lakes Greenstone Belt, Wabigoon Subprovince. The supracrustal rocks of the area are mainly mafic metavolcanic, mafic intrusive and intern1ediate intrusive rocks of the Rowan Lake Volcanic Group. The intrusive complex in the Denmark Lake area consists of peridotite, gabbro, diorite, quartz diorite and granodionte with enclosed remnants of metavolcanic, mafic intrusive and felsic intrusive rocks (Davies, 1973). The ultramafic rocks are devoid of xenoliths. Davies (1973) states: The oldest rocks of the complex appear to be ultramafic, with gabbro, diorite, quartz diorite. and granodiorite being successively younger. Some ultamamafic rocks may be younger intrusions. The general absence of mineral orientation in most rocks of the complex, the lack of obvious contact metamorphic effects, and the common occurrence of angular fragments suggest that the intrusions took place in a breccia zone which allowed rapid heat loss.'
