Ferri-Sepiolite in Hydrothermal Calcite-Quartz-Chalcedony veins on Nûgssuaq in West Greenland.
Ferri-sepiolite has been found in low temperature fracture veins in volcanic rocks. The veins are composed of an early calcite-quartz generation and a late generation of calcite, quartz, chalcedony and minor amounts of ferri-sepiolite. The late generation developed simultaneously with deformation of...
