Rocks at Trinity Beach Series 1 – Dark massive bedrock outcrops at the north and south ends of Trinity Beach, which lies along the coast to the north of Cairns in Queensland, Australia. Smaller hummocks appear through the sand and in the water. This rock type is Mount Formatine Granite which has been affected by metamorphism. It is a brown to brownish grey biotite-muscovite granite that has recrystallised to fine-grained aggregate of quartz, feldspars, and phyllosilicates. It has been moderately to intensely deformed with local mylonitic foliation. This series illustrates some of the variations in appearance of this rock at the location.
