New Locality, Formula, and Proposed Structure for Reyerite

Reyerite, a rare hydrated calcium silicate, has been discovered in chlorite-containing amygdules in a diabase dike in Rawlings quarry, Brunswick County, Virginia, that has been subjected to an episode of low-grade regional metamorphism. Microprobe, X-ray, optical, and infrared analyses of the Virgin...

Description
Summary:Reyerite, a rare hydrated calcium silicate, has been discovered in chlorite-containing amygdules in a diabase dike in Rawlings quarry, Brunswick County, Virginia, that has been subjected to an episode of low-grade regional metamorphism. Microprobe, X-ray, optical, and infrared analyses of the Virginia specimen and of reyerite from the type locality at Niakornak, Greenland, show that they are remarkably similar (space group P5 or P3, according to Cann, 1965).
