Intrusion-related gold deposits,osits (Figure 6.1). Here the spectrum is subdivided into: (a) intrusion-hosted stockwork/disseminated deposits of both porphyry and non-porphyry types, the former possessing all the essential geological attributes (especially multidirectional stock-works) of typical porphyry copper and/or molybdenum

Geochemical exploration for gold in glaciated terrain,allochthonous in relation to the bedrock they overlie. In the context of almost totally glaciated landscapes, which includes most of North America north of 40°N, Greenland and Iceland, most of Europe north of 50°N, extensive parts of Asia north of 60°N, parts of South America, and Antarctica, the se
