Sažetak
The heavy ion microprobe in combinatio with particle-induced X ray emmission was used to measured the distribution of manganese in freshwater mussel shells (Hyridella depressa) from the Nepean river in south-eastern Australia. Close to the ventral edge, bands with an elevated menganese content have been detected. These are correlated with growth bands in the mussels containing increased amounts of organic material, relative to the calcium carbonate matrix. Calcium minima, which were correlated to the annual growth rings, were measured close to umbo region of the shells.
