THE KIDD CREEK MINE is located within the Abitibi greenstone belt, near its west end, in an area known as the Porcupine mining camp (Fig. 5). The Abitibi belt, long known for its many major gold and base metal deposits, is the largest Archean (early Precambrian) greenstone belt within the Canadian Shield. In the Porcupine area, the greenstone belt is composed principally of Keewatin (older Archean) basic to intermediate volcanics, with subordinate felsic volcanics developed• locally. Greywacke, mainly of volcanic derivation, occurs associated with and overlying these volcanics. Timiskaming (younger Archean) sediments, principally coarse clastics, unconformably overlie the Keewatin volcanics and sediments. The reader is referred to Goodwin and Ridler (1970) •r. for a more comprehensive description of the Abitibi belt.
