Quartz dissolution associated with magnesium silicate hydrate cement precipitation [PDF]

open access: yesSolid Earth, 2021
Quartz has been replaced by magnesium silicate hydrate cement at the Feragen ultramafic body in south-east Norway. This occurs in deformed and recrystallized quartz grains deposited as glacial till covering part of the ultramafic body.
