Rare Earths in Geological Formations of Central Region of the Dniester River Basin, Republic of Moldova

Advances in Geology, Volume 2015, Issue 1, 2015., 2015
In the different varieties of crystalline basement of Archean and Proterozoic age and in Vendian (Ediacaran) basal layers of platform coverture in the Central Basin of the Dniester River were found relatively high concentrations of Lanthanum, Cerium, Yttrium, Ytterbium, and Scandium.

Redox bottom-water conditions in Neoproterozoic basins on eastern and north-eastern periphery of East-European Platform

Литосфера, 2015
The redox bottom-water conditions in the sedimentary basins, which existed during the Late Riphean-Vendian on the east and north-east (in modern coordinates) margins of the Baltic, are investigated.

Pan‐African Paleostresses and Reactivation of the Eburnean Basement Complex in Southeast Ghana (West Africa)

Journal of Geological Research, Volume 2012, Issue 1, 2012., 2012
This faulting tectonics analysis concerns the southernmost segment of the Dahomeyide Orogen and the West‐African craton eastern margin in southeast Ghana. The analysis of strike‐slip faults in the frontal units of the Dahomeyide Belt indicates that four distinct compressive events (NE‐SW, ENE‐WSW to E‐W, ESE‐WNW to SE‐NW and SE‐NW to SSE‐NNW ...

Desnacionalización, Regímenes Visuales y Resistencia: Gitanos Americanos en Ciudad de México

Cultural Anthropology, Volume 39, Issue 2, Page 171-193, May 2024.
