The rocks may have different textures
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.
The rocks may have different textures
Absolutely, yes!
Igneous
igneous rocks are composed of silicate minerals
As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent. As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.
welded tuff is a igneous rock so it is more likely for it to have the same minerals as most other igneous rocks.
igneous rocks
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
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.
