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).
