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需将样品制备为薄片或厚片（thin/thick section）。本数据集包含一系列贝壳横截面图像，并概述了薄片/厚片的制备流程。
本数据集属于某一科研项目的组成部分，该项目旨在评估通过微量元素与同位素分析，从贝壳地球化学特征中解译温度、盐度及重金属污染等环境记录的可行性。
