Volcanic reconstruction of the Archean North Rhyolite, Kidd Creek Mine, Timmins, Ontario, Canada

The Kidd Creek volcanogenic massive sulfide deposit is located in the southwestern part of the Archean Abitibi greenstone belt, approximately 24 km north of Timmins, Ontario.; The Kidd Creek mine stratigraphy is well established and consists of ultramafic flows, overlain by massive to flow banded to autobrecciated aphyric rhyolite, which in turn is overlain by aphyric rhyolitic volcaniclastic breccias that host the ore.; The North Rhyolite, which is located northwest of the ore body where it occupies a northwest trending F1 anticline, is the folded continuation of the Kidd Creek mine stratigraphy. The North Rhyolite stratigraphy consists, from oldest to youngest, of ultramafic flows, massive to brecciated aphyric rhyolite, massive to brecciated quartz porphyritic rhyolite intruded by gabbro sills, and basalt flows with minor interflow graphitic argillites.; The identification of the same stratigraphy and orientation of rhyolite ridges in the North Rhyolite as compared with the Kidd Creek mine stratigraphy indicates that the North Rhyolite was emplaced into the same subsidence structure as the Kidd Creek mine stratigraphy. Similar alteration patterns in the North Rhyolite and the Kidd Creek mine, as well as significant copper and zinc values within relatively unexplored rhyolite domes of the North Rhyolite suggests the potential for economically significant mineralization in the North Rhyolite.* (Abstract shortened by UMI.); *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).
