Microbial and inorganic control on the composition of clay from volcanic glass alteration experiments

Cuadros J.; Afsin B.; Jadubansa P.; Ardakani M.; Ascaso C.; Wierzchos J. (2013)

Biological activity plays a substantial role in the geochemistry of the Earth's surface. Particularly interesting are effects on clay formation because clays are abundant and have high surface-to-volume ratio, resulting ...
Pathways of volcanic glass alteration in laboratory experiments through inorganic and microbially-mediated processes

Cuadros J.; Afsin B.; Jadubansa P.; Ardakani M.; Ascaso C.; Wierzchos J. (2013)

Rhyolitic obsidian was reacted with natural waters to study the effect of water chemistry and biological activity on the composition and formation mechanisms of clay. Two sets of experiments (18 months, 6 years) used fresh, ...
