Mt Buninyong

"Mount Buninyong is a composite breached scoria cone from which issued a number of lava flows. There is a deep, well-defined central crater which has been breached on the north-western side. On the eastern side, the cone rises abruptly above older weathered lava flows but the topography around the western side is irregular as younger lava flows issued from here via the explosive breach of the cone. The breach may thus represent the site of a second crater. Small parasitic lava vents occur around the base. With over 200 m of local relief, Mount Buninyong is one of the highest scoria cones in Victoria. The lavas include olivine-rich xenoliths and megacrysts of clinopyroxene. Road cuttings expose coarse volcanic agglomerate and thin pods of lava." (source DPI).
