STRUCTURING OF THE EARTH'S CRUST AND THE PROBLEMS OF METALLOGENY Two contrasting periods are to be distinguished in the Earth evolution: 1) the 4.5-3.8 Ba age when mass amd enthropy of the Earth grew due to melting and h... V.,V.,ZHDANOV - ЗапискиВсероссийско...
Four billion years ago, Earth’s surface was covered with a thick basaltic crust and, similar to other rocky planets and the Moon, parts of this basaltic crust underwent partial melting to produce silicic crust. On Earth, silicic crust grew into the continents. An analogue of a pre-subduction...
scientists could not find a combination of properties for a spinning proto-Earth that would eject the right kind ofproto-Moon. According tocapturetheories, the Moon formed elsewhere in the solar system and was later trapped by the strong gravitational field of Earth. This scenario remained popular...

Recent studies suggest that nearly the same amount of biomass is present in subterranean and sub-seafloor settings as on Earth's surface1–4. The contact between the Late Devonian–Early Carboniferous (ca. 360–330 Ma) volcanogenic massive sulphide deposit in the Las Cruces mine (Seville, ...
