Iron Rich Rock (Long Reef - Sydney)

Long Reef is an interesting area from the point of view of geology. Beach sands include the minerals Ilmenite, rutile, zircon and monazite.

 

Bald Hill claystone and haemetite are in shot here. Bulgo sandstone is present, but not evident in this photo.

 

Most of the red comes from iron, so I'm told. But aluminium is also present in the form of kaolinite. In the 1880s there was a copper mine here at Long Reef.

 

A rather desolate looking scene. Hardly any plants in shot, as if it's in a dry region. Though the average annual rainfall here is over 1,200 mm per year.
