Vosnesensky Cu-porphyry deposit (Southern Urals): formation conditions, trace elements, sulfur isotopes and fluid sources

open access: yesGeoresursy, 2020
The paper shows new fluid inclusion and isotopic-geochemical data for minerals from sulphide-carbonate-quartz veins of Vosnesensky Cu-porphyry deposit. Fluid inclusions were analyzed by means Linkam TMS-600 cryostage equipped with Olympus BX 51 optical ...

pdFOAM: A PIC-DSMC code for near-earth plasma-body interactions [PDF]

open access: yes, 2017
Understanding the interaction of the near-Earth space environment with orbiting bodies is critical, both from a design and scientific perspective. In Low Earth Orbit (LEO), the interaction between the Ionosphere and orbiting objects is well studied from ...

Cenozoic Structurally Controlled Hydrothermal Activity Revealed by Apatite Thermochronology in the Convoy Range (Southern Victoria Land, Antarctica)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The Transantarctic Mountains form the longest and highest extensional mountain range on Earth, marking the boundary between the Antarctic craton and the Mesozoic‐Cenozoic rifted Ross Sea lithosphere. During the Cenozoic, deep offshore troughs, such as the Terror Rift, developed at the front of the Transantarctic Mountains in response to ...

The Role of Nurse Trees in the Plant Community of Park Grassland: A Case Study in Southern Brazil

open access: yesApplied Vegetation Science, Volume 28, Issue 2, April/June 2025.
Tree species facilitate the assembly of park grassland plant communities by altering environmental conditions and promoting woody and herbaceous species under their canopies. They support biodiversity and have potential for ecological restoration but may contribute to woody nucleation.

Modeling singular mineralization processes due to fluid pressure fluctuations [PDF]

open access: yes, 2020
Mineralization in the Earth's crust can be regarded as a singular process resulting in large amounts of mass accumulation and element enrichment over short time or space scales. The elemental concentrations modeled by fractals and multifractals show self-
