That would be andesite, as it is extrusive. The intusive rock with the same composition is diorite.

Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
What rock has the same composition as granite?
Rhyolite is the extrusive equivalent in chemistry and density of granite.
What is the name of igeneos rock?
There are many varieties of igneous rock. Igneous means it formed as a result of volcanic activity (the word igneous comes from the same root word as ignite) which produces extreme heat. Two main types of igneous rocks are intrusive (cooled gradually underground) and extrusive (cooled more rapidly at or near the surface.) Common examples of igneous rocks include granite, pumice, obsidian, basalt, diorite, andesite.
Two rocks that have the same general chemical and mineral composition?
According to the New York State Earth Science Reference Tables, the two rocks that have the same general chemical and mineral compositions are igneous rocks called andesite and diorite. They both have a composition that consists of quartz, plagioclase feldspar, biotite, pyroxene, and amphibole.
Are scoria and rhyolite the same in mineral composition?
Rhyolite is a rock type that is categorized by mineral composition. Scoria is a textural rock type. Like, Rhyolite can be smooth, or it can be scoria (sharper, bumpier, lots of vesicles).Think of it as a rock adjective.
Are diorite and andesite similar?
Yes. Diorite and andesite are igneous rocks with the same composition. Andesite is the extrusive equivalent of diorite, which is intruisive.
Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
What rock has the same composition as granite?
Rhyolite is the extrusive equivalent in chemistry and density of granite.
Do diorite and rhyolite have the same chemical composition?
No. Diorite has the same composition as andesite while Rhyolite has the same composition as granite.
Can the minerals which form an intrusive rock also form the same rock but is an extrusive rock?
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
What is sandblasting of rock by changing its chemical composition?
No. The chemical composition remains the same.
How are basalt and pumice the same?
Other than that they are both types of rock, very little. They have very different methods of formation and mineral composition. Basalt is produced from mafic lava flows, and shale is a product of sedimentary rock processes.
How is andesite different from rhyolite and basalt?
There are rocks that are extrusive (formed quickly on the surface of the earth) or intrusive (formed within the earth under slow cooling). Both types of extrusive or intrusive rocks can vary in composition from mafic (high iron and magnesium content) to silicic (less heavy ions like Fe and Mg, but with more of the lighter elements like Ca, Na, K, etc.). Extrusive rocks range from most mafic to less mafic as such: Basalt, Andesite, Rhyolite (and are all fine-grained b/c they cooled quickly). Intrusive rocks that cool more slowly and have larger crystals range from most mafic to less mafic as such: Gabbro, Diorite, Granite. Basalt and gabbro have a similar composition, just the crystal size differs from different cooling rates (same for rhyolite and granite).
Do Granite and Gabbro have the same chemical composition?
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
