Relationship between basalt stone and pumice

Basalt is the main component of oceanic crust, and is also a basic volcanic rock. The color of basalt stone is usually black. Pumice, also known as light stone or pumice, is a kind of glassy acidic volcanic extrusive rock with many pores, light weight and less than 1G / cm3, so it is called pumice.

Pumice

Pumice is typically light-colored and very vesicular. This rock is a trap to volcanic gases that tried to escape from magma but were unable to do it because they simply could not break out and formed many gas-filled vesicules instead. Trapped gases occupy much larger volume than they did when dissolved in …

Pumice vs Basalt

is that pumice is a light, porous type of pyroclastic igneous rock, formed during explosive volcanic eruptions when liquid lava is ejected into the air as a froth containing masses of gas bubbles as the lava solidifies, the bubbles are frozen into the rock while basalt is (mineral) a hard mafic igneous rock of varied mineral content; volcanic in origin, it makes up much of the earth''s oceanic crust.
