摘要：

Trace element contents (Mn, Fe, Sr) of a set of Lower Carboniferous brachiopod shell fragments have been measured using the Bochum proton microprobe. The resulting data are in good agreement with ICP measurements of the same shells and serve as a quantitative criterion to constrain the preservation state of the sample material for oxygen isotope analyses. They thus help to interpret correctly the isotope data. Linescans and elemental maps yield information on the lateral distribution of trace elements.
