recommendations! Published in 2018 at "International Journal of Earth Sciences"

DOI: 10.1007/s00531-018-1617-7

Abstract: The Western Sierras Pampeanas (WSP) of Argentina record a protracted geological history from the Mesoproterozoic assembly of the Rodinia supercontinent to the early Paleozoic tectonic evolution of SW Gondwana. Two well-known orogenies took place at… read more here.

DOI: 10.1007/s12583-018-0791-7

Abstract: Gondwana deposits are extensively found across the continents. Here we study the Middle Permian Barakar Formation from the marginal Gondwana Basin, eastern India, being deposited in a normal fault setting. Availability of extensive cores as… read more here.

DOI: 10.1016/j.gr.2019.06.010

Abstract: Abstract The provenance and maximum depositional age of Neoproterozoic to early Paleozoic sedimentary rocks from the Balonggonggaer Formation (BF) in the South Qilian belt (northern Tibetan Plateau) is established using LA-ICP-MS U Pb age determinations… read more here.

DOI: 10.1016/j.gr.2020.07.003

Abstract: Abstract Although Jurassic-Early Cretaceous sedimentary systems were extensively developed on northeastern Gondwana, deciphering their paleogeography has been complicated by poor exposure and the lack of a robust chronostratigraphic framework. The southeastern margin of the Carpentaria… read more here.

recommendations! Published in 2021 at "Gondwana Research"

DOI: 10.1016/j.gr.2020.12.033

Abstract: Abstract When the Cimmerian Continent separated from Gondwana and drifted northward to equatorial latitudes, sedimentary rocks on the continent underwent intense weathering, resulting in the formation of bauxite deposits. Gheshlagh is one such bauxite deposit,… read more here.

DOI: 10.1016/j.jafrearsci.2018.10.006

Abstract: Abstract The structural and stratigraphic evolution of rift basins has been documented globally from modern systems, outcrop and subsurface datasets. Extensive fragmentation and break-up of Gondwana during the Cretaceous created a complex suite of rift… read more here.

DOI: 10.1016/j.jsames.2018.02.006

Abstract: Abstract In the Famatina range, Sierras Pampeanas of Argentina (SW Gondwana), subvertical calc-alkaline lamprophyric dike swarms crop out through >300 km. The dikes cut Ordovician units with a prominent NW-SE trending and are covered by continental… read more here.

DOI: 10.1016/j.jsames.2019.102236

Abstract: Abstract During the mid-Carboniferous, ice centers located in present-day western Argentina disappeared until the late Cenozoic with glaciation of the Andes. The disappearance of mid-Carboniferous glaciers and the subsequent climate shift, recorded in the Paganzo… read more here.
