Abstract

Based on materials obtained in Cruise 37 of the R/V Professor Logatchev (2014‒2015), the paper discusses formation conditions, morphology, isotope age, and mineral and chemical composition of sulfide ores in the Pobeda-1 (17°08.7′ N MAR) and Pobeda-2 (17°07.45′ N MAR) hydrothermal ore fields (Pobeda ore cluster) discovered in blocks 37 and 39 confined to the Russian exploration area. Morphogenetic types of ores are defined and their formation conditions are examined.

Notes

  1. A significant part of iron sulfates was likely formed in the course of air drying after the sample recovery.
