Andesite
Andesite is a type of volcanic rock that forms when magma cools quickly. It is usually dark gray in color and can be found in many mountainous regions around the world.
外見
The Andesite is typically a fine-grained, dark grey to reddish-brown volcanic rock. It often has visible lighter mineral crystals, called phenocrysts, embedded in its finer matrix, giving it a speckled appearance that distinguishes it from uniformly colored rocks.

おもしろい事実
Andesite often erupts from dramatic, cone-shaped stratovolcanoes, like Mount Fuji!
Geologists study Andesite to predict future volcanic eruptions and protect communities.
It’s an "intermediate" rock, meaning its lava is thicker than basalt but runnier than rhyolite.
This rock forms a huge part of the dangerous "Ring of Fire" surrounding the Pacific Ocean!
