3.4 FRIABLE SANDSTONE AND CONGLOMERATE: SYDNEY BASIN Declining reserves of accessible alluvial sand and gravel have led to quarrying of the weak and weathered sandstones and conglomerates that outcrop extensively within the Sydney Basin. Similar deposits are worked in England, from the Bunter Pebble Beds and the Folkestone Sands.
