摘要:
A study of the Narrabeen Group in the southern part of the Sydney Basin has provided a more complete understanding of the conditions of deposition in the area during the Lower Triassic. The sedimentology of the sequence indicates that several different types of fluvial deposits are represented, with an upward succession from piedmont conditions with braided streams to a swampy deltaic plain. This sequence is interpreted as the onshore portion of a slow marine transgression, probably brought about by declining erosive activity in the hinterland.
