Geology Talk #4 - South Durras

Sunday 10 November

All Welcome
Our 4th and final geology talk.
Meet at car park opposite entrance to Murramarang Resort at 10.00am
See 260 million-year-old sandstone at the base of the Sydney Basin, including “drop stones” from old glaciers, fossil worm casts, fossil shells, fascinating ironstone formations and a narrow dolerite
dyke.
Walk to Dark Beach to see where these rocks sit directly above the 500 million-year-old rocks that are part of the same sequence seen at Melville Point on Trip 1.
This trip gives some idea of what might have been happening during the time between the formation of the 385 million-year-old Bingie Point rocks and the 30 million-year-old basalts at
Congo.
