... clusters and districts. The largest and most commercially important of them is the Central Aldan ore district, which is considered a regional ore-magmatic system (ROMS) within the Aldan Shield, a specific ore-magmatic province. The Aldan complex is a polychronous and polyfacies association composed...

... of the Central Aldan region. The Central Aldan ore district (CAOD) is unique by the wide occurrence of Mesozoic alkaline magmatism and associated gold and gold–uranium deposits ( Boitsov and Pilipenko, 1998 ; Kochetkov, 2006 ). For more than 80 years, Central Aldan has been one of the largest gold mining...
