They are commonly found under ground or near volcanoes
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Extrusive, Igneous rocks possibly lavas or ignimbrites.
you would normally find igneous rock which is formed by cooled magma.
When lava cools, it forms what is known as an extrusive igneous rock. Volcanoes are also associated with alteration from heat and fluids. Therefore you would expect to find extrusive rocks as well as altered rocks.
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.

You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.

the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment
Obsidian is an extrusive rock and is formed from rapidly cooling magma. Obsidian is also known as volcanic glass and one can find only sub-microscopic crystals in it. This is because it was cooled too fastly for large crystals to form. If the material that obsidian consists of were an intrusive rock and had a lot of time to cool down, one would find that it would be composed of easily visible crystals.
If you were to tunnel into the crust of the Earth, you would most likely find igneous rocks. These rocks are formed from the solidification of molten magma below the Earth's surface. Examples of igneous rocks include basalt, granite, and diorite.
you will find it in earths mantle because it is a kind of an igneous rock
