Phyllite from the Permo-Carboniferous Nambucca Beds is a notable example of layered rock. The layering is characterized by alternating domains rich in mica and quartz that originated through tectonic forces. Prominent crenulation cleavage and the development of new microlithons are also apparent. This geological feature can be found at Valla Beach, New South Wales, Australia, where its coordinates are -30.59363, 153.01398. For additional information, visit www.ausgeol.org.
