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.
The realm of black sands can be broadly divided into two parts, both of them having subdivisions. The most widespread type of black sand is composed of volcanic minerals and lava fragments. Such sands are especially common on the coasts of volcanic islands (Hawaiâi, the Canary Islands, the Aleutians, etc.). Black sand beaches are black because many volcanic minerals and rocks are dark-colored. Common rock types of volcanic islands are basalt (black when fresh), andesite (usually dark gray) and volcanic glass (often black in color).
