The Kiruna mining district, Sweden, known for the type locality of Kiruna-type iron oxide–apatite (IOA) deposits, also hosts several Cu-mineralized deposits including oxide–copper–gold (IOCG), exhalative stratiform Cu-(Fe-Zn), and structurally controlled to stratabound Cu ± Au. However relationship between IOA Cu-systems has not been contextualized within regional tectonic evolution. A broader ...

Despite the existence of a well-known set forecast and search criteria, only three gold silver epithermal deposits were discovered on territory Amguem-Kanchalan metallogenic zone, which has significant resource potential. The base enterprises developing them is extremely limited. aim study to clarify regional local conditions for localization gold-silver mineralization, forecasting searching pr...

Orogenic gold deposits have provided most of to humanity. These were formed by fluids carrying dissolved at temperatures 200–500 °C and crustal depths 4–12 km. The model involves mobilization as HS? complexes in aqueous solution buffered CO2, with precipitation following changes pH, redox activity (fO2), or H2S activity. In this contribution, the involvement carbonaceous organic matter is addre...

Silver Queen mint in central British Columbia, is located approximately 35 kilometres south of Houston and 3 kilometres east of 0wt.n Lake (Figure 2-7-1). Although currently inactive, it was worked briefly in the early 1970s for gold. silver, copper, zinc, lead and cadmium. The deposit is hosted by Cretaceous rocks of the informal Tip Top Hill group (78.322.67 Ma, K-Ar whole rock), with the age...

A variety of regional geoscience datasets from Nova Scotia have been co-registered and analyzed using a geographic information system (GIS). The datasets include bedrock and surficial geological maps, airborne geophysical survey data, geochemistry of lake-sediment samples, and mineral occurrence data. A number of line features, including structural lineaments, fold axes and formation contacts, ...

Recently published model of the global redox carbon cycle [1] asserts that cycle is a recurring sequence of related processes on the Earth. The sequence is called the orogenic cycle and consists of short-term orogenic and long-term geosynclynal periods. The orogenic period of the cycle is characterized with intense volcanism, magmatism and mountain building. The geosynclynal period is character...
