Biological Mineralization and Demineralization: Report of the Dahlem Workshop on Biological Mineralization and Demineralization Berlin 1981, October 18-23

normal and pathological mineralization in vertebrates but also with the interesting problems involved in the formation of in­ tracellular deposits of calcium oxalate in plants. Here cal­ cium carbonate and silica may also be involved in the mineral­ ization processes. Calcium carbonate is an important component in the formation of mollusc and avian shells. The observation that both calcite and aragonite may be formed in biogenic cal­ cium carbonate raises important questions as to what fact...
