Abstract

Fresh exposures in a former quarry at Little Bay in southeastern Sydney have revealed that earlier conclusions in relation to laterite stratigraphy and age are incorrect: the lateritisation is younger than the Little Bay Shale (Middle Miocene) and affects both the Hawkesbury Sandstone bedrock (Triassic) and the newly described Tupia Formation (Middle Miocene). Movement of iron oxides in rocks of the Sydney area can produce at least three different end-results, only one of which is a soil profile of lateritic type. [ABSTRACT FROM AUTHOR]
