摘要: The relationships of crystals to the organic matrix in which they form have been studied shell three bivalve mollusks, Pinctada martensii, Elliptio complanatus, and Crassostrea virginica, by comparing decalcified undecalcified sections. occurs as sheets. sheets nacreous regions (P. martensii E. complanatus) are 300–3000 thick cross section showed fibrils 100–200 diameter. Those calcitostracum (C. virginica) were 120–200 seemed be made up two or layers, each about 50 thick. Interlamellar was found only region continuous between horizontal crystalline layers aragonite. Intercrystalline enveloped aragonite calcite crystals. Intracrystalline surrounded penetrated dendritic elements making
