you would normally find igneous rock which is formed by cooled magma.
Since extrusive rocks are formed by lava (not magma), the rocks can be found easier because they are on the surface, whereas intrusive rocks are formed underground so they are either harder to get to or they are found in smaller quantities.
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
A lot, but they would all be igneous rocks.
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust

Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
Basalt and igneous rocks were formed by what we would call magma/lava
Diorite, being an intrusive igneous rock, formed underground by slow cooling, would have crystals large enough to be visible.
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
