Differential thermal study of Mg-bearing clays from saline lakes of Southern Tunisia
DTA-TG endo/exothermic double peak enstatite saline lake sediments trioctahedral smectites
2011/11/10
Abstract Clays high in Mg content occur frequently in the high saline environment of salt lakes in southern Tunisia. The DTA curves of these clays show a striking endothermic-exothermic reaction in t...
Chemical Weathering of Crystalline Rocks in the Catchment Area of Acidic Ticino Lakes, Switzerland
Acid precipitation Aluminum hydroxide Gneiss Iron hydroxide Weathering

Al-substitution Ferrihydrite Genesis Goethite Iron oxide Lake environment
2012/1/11
Fifteen iron oxide accumulations from the bottoms of two Finnish lakes (搇ake ores? were found to contain as much as 50% Fe. Differential X-ray powder diffraction and selective dissolution by oxalate s...
The Selective Adsorption of Sodium by Clay Minerals in Lakes Pontchartrain and Maurepas, Louisiana
Selective Adsorption Sodium Clay Minerals Lakes Pontchartrain
2012/2/20
Ion exchange analyses of the clay-sized fraction of sediments in Lakes Pontchartrain and Maurepas suggest the selective adsorption of Na at the expense of Mg. The literature suggests that Mg should be...
