摘要: The Turnagain Alaskan-type ultramafic intrusive suite – a type originally recognized in Duke Island, Alaska (Irvine, 1962, 1967b) lies 65 km east of Dease Lake, north-central British Columbia. It is fault bounded, 3.5 by 8 intrusion located on the margin Ancestral North America and part Mesozoic accreted island-arc terrane Quesnellia. intrusions have been Alaskan Panhandle, terranes Columbian Cordillera (Fig. 1), Ural Mountains Russia. term synonymous with Uralian-type, zoned, or concentrically latter being descriptive geometrical arrangement rock units present various suites. These bodies are exploration targets for chromite associated platinum-group-element (PGE) mineralization (
