Shell cross sections of the bivalve Crassostrea gigas collected from Little Swanport, Tasmania

Petrological and some geochemical analysis methods require the sample to be made into a thin or thick section. This record provides a series of shell cross-sectional images and also outlines the process involved in thin/thick section preparation.

This is part of a project that assesses the viability of interpretating environmental records (such as temperature, salinity and heavy metal pollution) from shell geochemistry through trace element and isotopic analysis.
