Sericitic alteration
Process of mineral alteration
Sericitic alteration or sericitization is a type of hydrothermal alteration characterized by the development of fine-grained white mica assemblages collectively referred to as sericite. In the Buchans-Roberts Arm Belt of Newfoundland, these assemblages include muscovitic illite, phengite, and paragonite associated with hydrothermal alteration zones.
