Apatite of Alkaline Rocks of the Vishnevogorsky Complex, South Urals [PDF]

МИНЕРАЛОГИЯ (MINERALOGY), 2019
Apatite Ca5(PO4)3(F,Cl,OH) is a widespread accessory mineral of alkaline rocks of the Vishnevye Mountains in the Urals. There are small bodies of carbonatites and micaceous rocks, where apatite is a rock-forming mineral. The rocks mostly contain fuorapatite and, locally, apatite-(CaOH). The Cl-bearing apatite is rare. Apatite is enriched in Na2O (up to

Natural and technogenic geodynamic processes in the south ural [PDF]

E3S Web of Conferences, 2020
In this paper is presented hydro-geodynamics and geodynamics in the South Urals. Seismicity and geodynamics induced by hydrocarbon production by summarizing the published case studies are considered. Changes in hydro-and gas dynamics affect changes in the geodynamics of the crust.

Future Changes in Tropical Cyclone Exposure and Impacts in Southeast Asia From CMIP6 Pseudo‐Global Warming Simulations

Earth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract In this Pseudo‐global Warming study, potential future changes in the Southeast Asia tropical cyclone (TC) exposure climatology are quantified. One hundred and seventeen landfalling TCs in the last 20 years are simulated with their current climate conditions and also with the Coupled Model Intercomparison Project Phase 6 (CMIP6) ensemble ...
