AC18.10661

The material consists of andesite (ferroan enstatite) rock sourced from an operating (Allandale) quarry located approx. 40 km northwest of the city of Newcastle in New South Wales, Australia. This light grey, Carboniferous rock forms a small, hydrothermally altered, remnant volcanic (Blair Duguid) inlier within gentle to moderately folded Permian shallow marine sediments of the Sydney Basin. The mineralogy consists of andesine plagioclase (44 %), vermiculite, smectite (37 %), quartz amygdales (13 %) and hypersthene clinopyroxene (3 %).
