Basalt actually has another name, volcanic rock. By this name, you may think that this type of stone is commonly used. It is the main component of the Earth's oceanic crust and the Moon's lunar mare, as well as an important component of the Earth's continental crust and the Moon's lunar landmass. Although many people have seen or used basalt stones, they are not very familiar with their characteristics. Below, we will briefly understand their features.
The color of basalt stones is usually black or dark green, but their color varies in different environments due to their dense texture and heavier specific gravity than ordinary granite, limestone, sandstone, and shale. But some basalt stones have a lot of pores, which reduces their weight and even allows them to float in water. Do you know why it is called volcanic rock? Because this type of stone can form in a high temperature environment of 1600 degrees, it has high temperature resistance.

Columnar joints in basalt stones-In basalt lava flows,vertical condensation surfaces often develop into regular hexagonal columnar joints.
