PROGNOSTIC ESTIMATE OF NOBLEMETAL RESOURCES IN PROMISING ORE DISTRICTS OF THE KARELIAN REGION

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
The gold and platinoid resources of the Karelian region are expected to increase. Our prediction is based on the leading genetic types of noble-metal mineralization known in the region such as the low-sulphide Pt-Pd type in layered plutons and gabbro ...

Barren ground depressions, natural H2 and orogenic gold deposits: spatial link and geochemical model

, 2022
A review of the localities in continental rocks where H2-rich gases have been reported, showed that they are mainly located near gold deposits. Two types of geomorphological features known as markers of gas venting in sedimentary basins were also ...
