At 1000 °C, kappa- and alpha-alumina coexisted, but kappa-alumina could only be characterized by SAED. The details of the internal organization of the transition alumina pseudomorphs were clearly ...

Applying all relevant information from the rover, the nodules are interpreted as pseudomorphs after original crystals of vivianite, (Fe2+,Mn2+)3(PO4)2 center dot 8H2O, that cemented the sediment soon ...

This study explores interactions between As and Fe(III) minerals, predominantly schwertmannite and jarosite, in acid mine drainage (AMD) via observations at a former mine site combined with mineral ...

Mineralogy is the study of minerals, the building blocks of rocks, which are naturally-occurring, crystalline solids with a set chemical make-up. This includes the study of the chemical ...

Portions of the veins display minor repetitive banding, coarsely-bladed calcite, and quartz pseudomorphs of the calcite, within larger zones of phreatic-type brecciation that typically represent ...

The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and ...
