Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.

Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.

The rocks may have different textures
Absolutely, yes!
because racks are rocks and minerals are minerals
I think is melted minerals!
Igneous Rocks
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.

Although chemically equivalent, they would be different in their method of formation. Granite is an intrusive igneous rock, cooled from magma under the surface. The rock rhyolite is the chemical equivalent of granite, but formed on the surface, making it an extrusive igneous rock. Intrusive rocks have larger crystals.
