Potential use of Argentine kaolinite clays as pozzolanic material
(Elsevier Science, 2014-11)
Different Argentine kaolinitic clays were selected to study their potential pozzolanic activity. The incidence of several factors such as the origin of deposits (primary or sedimentary clays), mineralogical composition, ...
Kaolinitic calcined clays: Factors affecting its performance as pozzolans
(Elsevier, 2012-03)
Five natural kaolinitic clays from different regions of Argentine, with different kaolinite content, different impurities and different degree of crystallinity were calcined in a fixed-bed electrical furnace at 700 °C. ...
First principles study of structural properties and electric field gradients in kaolinite
(Elsevier Science, 2019-03-01)
This work reports a gauge-including projected augmented waves (GIPAW) method study of the structural and electronic properties of kaolinite (Al2Si2O5(OH)4). Different equilibrium structures were determined, and the ...
Hydrometallurgical extraction of Al and Si from kaolinitic clays
(Fundação Gorceix, 2017-12)
Herein is presented the results of a study on the hydrometallurgic extractionand recovery of aluminum and silicon by leaching of kaolinitic clays with HF. Thestudied extraction parameters were: temperature, reaction time, ...

Diagenetic model of the Bajo Barreal formation (Cretaceous) in the southwestern flank of the Golfo de San Jorge Basin (Patagonia, Argentina)
(Elsevier, 2017-12)
This paper analyses the diagenetic evolution of sandstones belonging to the Bajo Barreal Formation (Cretaceous) in the Golfo de San Jorge Basin (Patagonia, Argentina). The Bajo Barreal Formation includes the main reservoirs, ...
Origin of kaolin deposits in the “Los Menucos” area, Río Negro Province, Argentina
(Mineralogical Society, 2005-12)
Kaolinite deposits, hosted by rhyolitic tuffs, are found in the SE of the ‘Los Menucos’ area (Province of Río Negro, Argentina). The most representative examples are from the Blanquita and Equivocada mines. To discover the ...
Evidence of cyclic climatic changes recorded in clay mineral assemblages from a continental Paleocene-Eocene sequence, northwestern Argentina
(Elsevier Science, 2018-06)
The continental Paleocene-Eocene sequence investigated in this study belongs to the Salta Group, deposited in an intracontinental rift, the Salta Basin (NW Argentina), that evolved from the lower Cretaceous to the middle ...
