The Mineralogical Association of South Africa (MINSA) was formed to foster interaction among mineralogists in South Africa. Our membership covers a broad spectrum of interests, including petrology and geochemistry, and special interest groups in clay minerals, fluid inclusions, volcanology, and the Witwatersrand.
MINSA is affiliated to the Geological Society of South Africa.
