Rare metal granites in the structures of the Russian sector of Pacific ore belt
Записки Горного института, 2016 Data are presented on the geology of areas of rare metal granites proliferation in the Russian sector of the Pacific Ore Belt that make one take a fresh look at the East Asian granitoid area to update its metallogeny. History is reviewed of studying rare

Constraining the geotherm beneath the British Isles from Bayesian inversion of Curie depth: integrated modelling of magnetic, geothermal, and seismic data [PDF]
Solid Earth, 2019 Curie depth offers a valuable constraint on the thermal structure of the lithosphere, based on its interpretation as the depth to 580 ∘C, but current methods underestimate the range of uncertainty. We formulate the estimation of Curie depth within

Meteoritics &Planetary Science, EarlyView.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

U-Pb (Zircon) Ages of Metavolcanic Rocks From the Itaiacoca Group: Tectonic Implications [PDF]
Geologia USP. Série Científica, 2003 The main aim of this work is to present and discuss the U-Pb ages obtained for zircon grains from metavolcanic rocks of theItaiacoca Group. The Itaiacoca Group is a metavolcano-sedimentary sequence, which occurs as a narrow belt between theCunhaporanga ...

Meteoritics &Planetary Science, EarlyView.Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses

HYDRODYNAMICS AND HEAT AND MASS TRANSFER IN MUSHROOM-SHAPED HEADS OF THERMOCHEMICAL PLUMES
Геодинамика и тектонофизика, 2018 The model of a thermochemical mantle plume is described. The scheme of origination of the plume from the core-mantle boundary is presented. The basic ratios for determining the thermal power and the diameters of thermochemical plumes are given.
