No -- it's a type of rock, often a composite. Primay types are igneous (made by fire -- vulcanism), sedimentary (sea beds) and composite (a mixture of other types). In almost every case, all of these types are defined as how the substance at hand was created and in most cases they are not pure minerals.
Color, as it is not a reliable indicator due to variations within the same type of rock. Texture, mineral composition, and formation conditions are typically used to classify igneous rocks.
It's an igneous rock. There is a lot of fluorite in Illinois because this is an area of weakness in the bedrock where magma injections are present. Technically speaking, fluorite is a mineral, and not a rock. However, it is a mineral mostly formed in igneous area's
Igneous rocks can be classified based on their texture and mineral composition. Texture is determined by the size of the mineral grains, with coarse-grained rocks forming from slow cooling and fine-grained rocks forming from rapid cooling. Mineral composition can also help differentiate igneous rocks, such as identifying the presence of minerals like quartz, feldspar, or olivine.
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
Soils derived from igneous rocks tend to be more fertile than those derived from metamorphic rocks. This is because igneous rocks have a higher mineral content that can break down into nutrients essential for plant growth. Metamorphic rocks may have fewer minerals available for plant uptake, resulting in less fertile soil.

Rocks with large, easily identifiable minerals, such as granite and diorite, are easy to classify. These rocks belong to the intrusive igneous rock category and typically have distinct mineral compositions that allow for easy identification.
Extrusive igneous rocks have very small crystal grains.

Because the rock feels like it beotch.
I would assume it would be igneous due to the massive amounts of magma in the earth's crust.

They use the mineral composition, color, and texture.

The rock would have visible mineral crystals--a phaneritic texture.
