Anomalously silver-rich vein-hosted mineralisation in disseminated-style gold deposits, Jiaodong gold district, China

Grade and Tonnage Data for British Columbia Mineral Deposit Models

The Mineral Potential Project currently being undertaken in British Columbia requires estimation d unknown mineral resources. The method of resource assessment known as the BC Mineral Resource Assessment Process [19931. is described by Kilby (1995, this volume) and in Grunsky et al. (1.994). The method is based on the three-part ssessment methodology developed by the United States Geologica...

Geochemistry and Metallogenic Model of Carlin-Type Gold Deposits in Southwest Guizhou Province, China

Natural gold particles in Eucalyptus leaves and their relevance to exploration for buried gold deposits

Eucalyptus trees may translocate Au from mineral deposits and support the use of vegetation (biogeochemical) sampling in mineral exploration, particularly where thick sediments dominate. However, biogeochemistry has not been routinely adopted partly because biotic mechanisms of Au migration are poorly understood. For example, although Au has been previously measured in plant samples, there has ...

Orogenic gold deposits: A proposed classification in the context of their crustal distribution and relationship to other gold deposit types

The so-called ‘mesothermal’ gold deposits are associated with regionally metamorphosed terranes of all ages. Ores were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens. In both types of orogen, hydrated marine sedimentary and volcanic rocks have been added to continental margins during tens to some 100 milli...
