The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic (400 to 250 million years ago). The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed. It contains a sandy member known as the Beacon Heights Orthoquartzite.
