basalts
Dark igneous stones
Basalts is the plural of basalt, a dark, dense volcanic rock that forms when lava cools rapidly.
It's the most common rock type in the Earth's crust and covers much of the ocean floor.
Geologists distinguish between different basalts by their mineral composition and texture: The Hawaiian islands are built from successive layers of basalts.
