Sandstone Patterns

Liesegang banding at Maitland Bay Beach.

 

Terrigal Formation sandstone from the Triassic at Maitland Bay beach.

 

On the other side of the Hawkesbury, the corresponding rocks are Newport Formation sandstone. Above them both, the Hawkesbury sandstone, all from the Triassic.

 

Siderite is the mineral causing the colouration in these rocks, (FeCO3).
