Балыгычано-Сугойский континентальный рифт: строение, основные черты развития и металлогении

Abstract

The Balygychan-Sugoy structure was formed in the zone of expansion, presumably resulting from the reverse of the Omolon microcontinent northern flank to the south and southeast along the Omsukchan deep fault, and developed as a continental rift. By the end of the Early Cretaceous, the rift was filled with thick coal-bearing molasse. Volcanic, intrusive , and various ore formation processes were actively occurring in the rift zone. The data on the geological structure and the history of the structure development confirm its rift nature.
