On Zones of Finely Dispersed Sulfidization in Northeast Russia

摘要

Until recently, the main role in the formation of ore deposits was thought to belong to magmatogenic processes. At the same time, researchers gradually arrived at the conclusion that large ore-bearing zones with finely dispersed sulfide mineralization represent autonomous geological objects with a long development history, which frequently exceeds the duration of mag-matic and tectonic cycles. In many works, it has been shown that a substantial role in ore formation belongs precisely to sedimentary and sedimentary-volcano-genic sequences, which are characterized by a relatively high metalliferous potential.
