A University of Toronto study suggests why giant gold and copper deposits are found at some volcanoes but not others, a finding that could point prospectors to large deposits of these and other valuable metals. "There's one characteristic that is common to all of these big gold and copper deposits anywhere in the world," says Professor James Mungall of the Department of Geology. The ocean's crust that is pushed down under a volcano starts to melt, which it doesn't normally do. His study, which appears in the October issue of Geology, examines the "Rim of Fire" volcanoes that surround the Pacific Ocean.
