Active basalt quarry at base of eastern flank of the volcano.
Known for fine olivine bombs and large anorthoclase xenocrysts.
Fumaroles and quartz-rich xenoliths also occur, but are rare.
The mineralogy has not been studied in detail yet, but mineralogical work is underway (B. Birch & U. Kolitsch).

Mt Shadwell Quarry is located in Ararat Road, MORTLAKE.
