Thin section descriptions for Heard Island rocks

Thin sections were prepared at the University of Tasmania. Rocks were washed, cut and dried. 30 micron thick polished thin sections were prepared. The thin sections were described with a microscope at the University of Tasmania. Mineral types and abundances were characterised for each thin section. The composition of the rocks are listed in the description. The composition was determined through XRF analysis (see XRF data sheet for these samples).

薄片制备于塔斯马尼亚大学。岩石经过清洗、切割和干燥处理。制备得到30微米厚的抛光薄片。这些薄片在塔斯马尼亚大学通过显微镜进行描述。对每个薄片的矿物类型及含量进行了表征。岩石的成分列于描述中。成分通过X射线荧光光谱分析（XRF analysis）测定（详见这些样品的XRF数据表）。
