Abstract

Indicates that the calcite of sea urchin spines and skeletal plates forms in mosaic crystals. Both coherent and incoherent boundaries were observed between slightly misaligned crystallites. Small domains show an ordered superstructure. The most appropriate model has Ca:Mg=3.1 and alternating Ca layers and Ca and Mg layers along c. -from Authors
