Biologically enhanced dissolution of a pyrite-rich black shale concentrate
(1997-01-01)
The acid leaching of a pyrite-rich black shale concentrate (7% S) was tested in this study. The experiments were performed at 5-30% pulp densities and with inoculations of Fe- and S-oxidizing thiobacilli (Thiobacillus ...
Geochemistry of aggradational - Progradational sequence sets of the Upper Jurassic – Lower Cretaceous Vaca Muerta shales (Añelo area, Neuquén Basin, Argentina): Relation to changes in accommodation and marine anoxia
(Pergamon-Elsevier Science Ltd, 2019-08)
Unconventional shale plays have received marked attention over the last years because of their economic potential for hydrocarbon generation. The size and geology of the Neuquén Basin of western Argentina lends to large ...
Lower Cretaceous anoxic conditions IN the Austral basin, south-western Gondwana, Patagonia Argentina
(Pergamon-Elsevier Science Ltd., 2014-02)
The reconstruction of palaeo-oxygenation levels in marine deposits from the Cretaceous has obtained a huge interest all around the world in recent years. This fascinating topic is here pointed out for the first time in the ...
Alternative interpretations of some earliest ediacaran fossils from China
(2013-03-01)
In a letter to Nature (February, 2011), Xunlai Yuan and collaborators recorded carbon compression fossils from black shales of the Lantian Formation (Ediacaran), southern Anhui Province, South China. The new fossils, ...
