There are a couple examples.
Coal is a rock, but it is organic and so does not contain minerals.
Obsidian and pumice are both varieties of volcanic glass. Since they lack a crystal structure, they are not composed of minerals
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
The rock formed when dissolved minerals reform is called sedimentary rock, specifically a type known as chemical sedimentary rock. This occurs when minerals precipitate out of solution, often due to evaporation or changes in temperature and pressure, leading to the accumulation of mineral crystals. Examples include limestone and rock salt. These rocks can provide valuable insights into past environmental conditions.
You say it as ' Igneous ROCK ' and ask whether it is a rock..
A rock is composed of minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. Rocks can be made up of one type of mineral or a combination of different minerals.
Coprolite is a type of fossilized feces that has turned into a type of sedimentary rock known as a phosphate rock. It is formed through a process called mineral replacement, where the original organic material is replaced by minerals over time.
Sandstone is the sedimentary rock formed from weathered rock.

Sandstone is one possible form.

Sedimentary rock is found at the bottom of lakes and rivers. This rock is formed from minerals and organic particles.
Well, the type of rock that you have is affected by things such as the minerals, like salinity (saltyness), altitude, erosion, age, etc.

The rock described would be a clastic sedimentary rock.
Rocks composed of evaporite minerals, such as halite and gypsum, are rocks formed by evaporation of fluids.
