Abstract

Calcifications of the pineal gland in the form of calcospherulites have been studied by optical microscopy, electron microscopy, electron probe analysis, X-ray diffraction, thermogravimetry, and infra-red and chemical analysis. Complex calcospherulite textures have been observed which have a granular substructure made up of apatite crystals averaging 218 Å in length and 38 Å in width. These apatite crystals appear to be a carbonate-containing hydroxyapatite, mineralogically similar to enamel.
