The first map of occurrences and metal deposits in Haiti was recently submitted to the Haitian authorities who plan to adopt new measures to modernize the Haitian mining sector. Geologist Booz Walemba indicates that in the momentum of exploration Haiti should start producing gold and copper and other ores in the coming years. Gold ore, copper ...

Most Tertiary ore deposits in the southern Rocky Mountains are associated with eroded volcanoes or shallow underlying plutons. Distributions and compositions of the igneous rocks vary complexly with time, apparently reflecting evolving boundaries between the American, Farallon, and Pacific plates nearly 1,000 km to the west.

The strategic mineral W-Sn deposits in China are mainly concentrated in South China, and many rare metal mineralizations, such as Li, Rb, Be, Nb, Ta, etc., are often coproduced with them. However, the genetic relationship between them is unclear. Based on the analysis of research data related to granite-related rare metals and W-Sn deposits in South China, we believe that …

8.1 Metal Deposits Steve Earle. The earliest known metal mines, in Bulgaria and Serbia and some neighbouring areas of southeastern Europe, date back about 7000 years, with the main metal of interest being copper. Copper was also mined and used in the Great Lakes region of North America at around the same time.

Haiti is the second largest source of iridium on the planet. The destabilization of the country is ongoing. The largest source of iridium is South Africa. It is also one of the most prolific exporters of diamonds to this day. Diamond mining is incredibly destructive to the native landscape, visibly disfiguring the land beyond repair.

Porphyry deposits of the Cu-Mo-Au-Re metal spectrum mainly occur in arc settings, but only some segments of the same arc host significant metal resources. The factors controlling the variable metal endowment in magmatic arcs remain unclear.

Volcanic rocks host significant base and precious metal ore deposits. But what is an ore deposit? The term ore deposit is an economic, not a geological term, and refers to a naturally occurring material which can be extracted, processed, and delivered to the marketplace or technology at a reasonable profit.

Abstract The Jinlongshan gold deposit, Shaanxi Province, central China, is a large deposit (>150 t Au) in the Southern Qinling Orogen. Gold mineralization is hosted in Upper Devonian to Lower Carboniferous carbonaceous clastic-carbonate sequences. Four stages of pyrite and paragenetic sulfides have been identified based on morphology and paragenesis.
