Shell cross sections of the bivalve Mytilus galloprovincialis 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.岩石学及部分地球化学分析方法要求将样品制备成薄片或厚片。本记录提供了一系列贝壳横截面图像，并概述了薄片/厚片的制备流程。该记录属于某项目的一部分，该项目旨在评估通过微量元素和同位素分析从贝壳地球化学数据中解读环境记录（如温度、盐度及重金属污染）的可行性。
