Black sand beaches can be formed by the Earth's weather patterns causing lava to erode into the sandy beaches. The tides help break up the lava that rests on the shallow ocean floor -- turning it into a fine sandy material -- and then will redeposit the sand on the beach.hough black sand beaches are a rare occurrence throughout the world, there are several regions where they are common. Islands that have black sand beaches include Iceland, Hawaii, Indonesia and Polynesia.
Beach Sediments can range from silt, sand, gravel to boulders. Most sand has its origins from rocks on the land. The sand at Muriwai is mainly black iron sand (also known as Titomagnetite). This sand originates from the volcanoes of the Central North Island and Mount Taranaki on the West Coast. Rivers from these mountainous regions have eroded volcanic material and carried sediment to the sea. From there longshore drift has transported the black sand up the coast and deposited on beaches.
