{{Short description|Process of mineral alteration}} {{One source|date=May 2026}} '''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.<ref>{{cite report |last=Sparkes |first=G.W. |year=2022 |type=Current Research |title=Short wavelength infrared spectrometry studies of sericitic alteration zones, southern Buchans–Roberts Arm Belt, Newfoundland |publisher=Newfoundland and Labrador Department of Industry, Energy and Technology |id=22-1 |pages=85–118 |url=https://www.gov.nl.ca/em/files/CurrentResearch_Sparkes_2022.pdf |access-date=2026-05-08 |archive-url=https://web.archive.org/web/20251231060855/https://www.gov.nl.ca/em/files/CurrentResearch_Sparkes_2022.pdf |archive-date=2025-12-31 }}</ref>
