More model informationThis tectonic mélange crops out at Miner’s Beach, Port Macquarie, NSW. It contains a variety of phacoids, dominantly greenschist facies metabasalts, chert and some blueschists. Some metabasalt phacoids in the outcrop (including this one) display vesicles around their margins and have been interpreted a submarine pillow basalts. The sense of shear is also easily interpreted for this phacoid with the asymmetry indicating a top-to-the-left motion. Lens cap is 64 mm in diameter.
