Mount Roland in Tasmania stands at 1,234 meters high and is primarily composed of conglomerate, a type of sedimentary rock that forms in riverbeds or alluvial fans. This conglomerate is rich in silica (quartz), making it hard and resistant to erosion. It belongs to the Owen Group, a geological unit that dates back to the Late Cambrian to Early Ordovician periods. The conglomerate features well-rounded cobbles and pebbles made of quartzite, sandstone, chert, and reef quartz.
