Dromedary pyroxenite

This sample of pyroxenite originates from an igneous dyke situated on the coast at Pooles Point, located on the southern coast of New South Wales, and is a component of the Mount Dromedary Complex. The complex dates back to the Cretaceous period, approximately 100 million years ago, and is characterized by potassic intermediate plutonic rocks such as monzonites and syenites. This specimen is predominantly composed of large cumulous augite crystals, with rare occurrences of olivine. Intercumulous phases consist of magnesio-hornblende and phlogopite, along with minor plagioclase, magnetite, and apatite. Mount Dromedary was christened by James Cook in 1770 due to its resemblance to the hump of a camel from offshore. The mountain and associated national park are now referred to as Gulaga and hold significant cultural importance for Aboriginal communities.
