Shell cross sections of the bivalve Ostrea angasi collected from Severs Beach, NSW

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为薄片或厚片。本数据集包含一系列壳体横截面图像，并概述了薄片/厚片制备的相关流程。本数据集隶属于某科研项目，该项目旨在通过微量元素与同位素分析，探究从壳体地球化学数据中解译温度、盐度、重金属污染等环境记录的可行性。
