摘要
During cruise 41 of the R/V Professor Logachev in 2019, two new ore fields were discovered within the Russian exploration area of the Mid-Atlantic Ridge. The Korallovoe ore field is located in the middle part of the rift valley ridge and lies on a gentle slope in the depth range of 2800-2850 m. The Molodezhnoe ore field is located approximately 5 km northeast of the Korallovoe field and lies on a less steeper section of the slope at depths of 3500-3550 m. The Korallovoe and Molodezhnoe fields are confined to an outcrop of a gabbro-peridotite massif on the western side of the Mid-Atlantic Rift valley. The total number of discovered ore fields in the Russian exploration area has increased to 14.
