The metallogenic efficiency of the marginal sea lithosphere of Northeastern Asia is associated mainly with the ore formation variety of the remaining cratons and microcratons that defined the structural peculiarity of the region; these are setoffs of the Precambrian basement, brachyform, anticline highs, and genesis of rifts within TMA periods. These formations allowed us to explain the reasons fo...... hiện toàn bộ
Palladogermanide PdGe2 from Sulfidized Anorthosite of the Yoko-Dovyren Intrusion: First Finding in RussiaPleiades Publishing Ltd - Tập 485 - Trang 458-460 - 2019

The Yoko-Dovyren ultramafic–mafic layered intrusion includes the Baikal deposit of Cu–Ni sulfide ores with Pt–Pd mineralization in the bottom part, and “horizons” and pockets of low-sulfide ores with Pt–Pd mineralization at the upper levels of the section. The highest concentration of Pd, Pt, Au, Ag, Hg, and Cd, as well as the widest variability in the noble-metal minerals, is typical of the vein-...... hiện toàn bộ
Events at the turn of the Eocene and Oligocene in the Central Eurasia Region (middle latitudes)Pleiades Publishing Ltd - Tập 473 - Trang 273-276 - 2017
M. A. Akhmetiev, Yu. O. Gavrilov, N. I. Zaporozhets
The Eocene and Oligocene transition sections (Priabonian–Rupelian) of the Aral–Turgai, West Siberian, Volga–Don, and Crimea–Caucasus regions have been studied in detail [1], and the global biospheric crisis events have been estimated at the turn of the Eocene and Oligocene. In spite of the idea of the gradual regression in the Priabonian with drainage of the inner sea basins, it has been establish...... hiện toàn bộ
