Extract

Scawtite was first described at Scawt Hill as a secondary mineral occurring in vesicles and venules in melilite of a melilite-rich hybrid of the endogenous contact-zone. Since then scawtite has been identified in a gehlenite-vesuvianite-ealcite-rock from the contact-zone of a gabbro in the Little Belt Mountains, Montana. The present note records a further occurrence of scawtite at Scawt Hill in a different patagenesis, viz. in association with and replacing spurrite of the exogenous contact-zone.
