摘要：
A shell of Pecten maximus (L.) whose growth under experimental conditions in the Bay of Brest was previously studied is examined under cathodoluminescence. Thus, growth lines hidden on cross-sections by the foliated microstructure of calcite are revealed. Winter growth rings are marked by orange luminescent stripes whereas the other parts of the shell have a weak blue luminescence. The presumed activator is Mn2+. Its concentration in shell calcite might also depend on seasonal changes of estuarine environment. Bioeroded zones have a characteristic bright luminescence with a palisade aspect.
