Principal Features of Epithermal Lode Gold Deposits of Circum-Pacific …

Production from epithermal primary lode gold deposits along the Circum-Pacific rim exceeds one million ounces annually, from around 20 countries. Distribution of this important deposit type coincides with, and is genetically related to, convergent plate boundaries and the chain of associated volcanic-plutonic activity framing the ocean basin.

Tectonic setting of synorogenic gold deposits of the Pacific …

More than 420 million oz of gold were concentrated in circum-Pacific synorogenic quartz loades mainly during two periods of continental growth, one along the Gondwanan margin in the Palaeozoic and the other in the northern Pacific basin between 170 and 50 Ma.

Mineral Resources of North America

Among all the continents, North America is endowed with more than its relative share of the world's mineral resources, particularly those upon which the industry of the 20th century is principally dependent -coal, petroleum, natural gas, and iron. North America has about one sixth of the known coal reserves of the world.

Host minerals for gold have been of great interest to exploration geologists and metallurgists for a variety of reasons. The depletion of high grade ores in many parts of the world requires that greater attention be given to the study of host min-erals for gold. Some host minerals have been employed in exploration as traces for gold. They are also essential in the …
