More model informationThis outcrop shows a large metabaslt phacoid (~5 metres) enclosed in the strongly sheared greenschist matrix of a tectonic mélange at Miner’s Beach, Port Macquarie. Along the edge of the facoid is a prominent drag fold indicating a dextral sense of shear along the margin. The foliation in the matrix is approximately east-west in orientation.
These rocks form part of the accretion-subduction complex of the Southern New England Orogen.
The lens cap is 62 mm in diameter.
