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.
Granite is a coarse grained igneous rock without Pyroxene.
When minerals melt, they can form an igneous rock called granite. Granite is typically composed of quartz, feldspar, and mica minerals that solidify from a molten state, either deep underground or at the Earth's surface.
Amethyst is a type of mineral from the quartz family, not a rock. Quartz is formed in igneous, metamorphic, and sedimentary environments, but amethyst specifically is often found in metamorphic 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
no
Obsidian is an igneous rock that technically is not composed of minerals. It is a natural glass.
You say it as ' Igneous ROCK ' and ask whether it is a rock..
No. While some rocks are composed almost entirely of a single mineral, this is generally not the case for igneous rocks.
Igneous rock is formed when melted minerals cool and harden. This process can happen either beneath the Earth's surface (intrusive igneous rock) or on the surface (extrusive igneous rock). Examples of igneous rocks include granite, basalt, and obsidian.
No it is not. Sedimentary rocks are made of minerals.
Mafic igneous rock. ( due to Ferromagnesian minerals).

Igneous rock is formed from melted minerals that have solidified and cooled. This process can occur either beneath the Earth's surface, forming intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks.
of course :P
igneous rock
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
