What is the mohs scale for Feldspar?
Basalt scores an 8 on the Moh's scale. This makes it harder than quartz and vanadium, but weaker than boron and titanium carbide. It can easily scratch steel and glass. It is just about as hard as topaz. Basalt is also an igneous rock, formed by hardened lava, which explains why it is so hard.
Is granite a colloid?
Granite is a very hard, crystalline igneous rock that is mainly composed of quartz. It is not a colloid but a heterogeneous mixture.
What is the composition of granite?
Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.
What qualities of igneous rocks have long made them useful for tools igneous rock?
Extrusive igneous rock: Obsidian. Quality of conchoidal fracture making them easily workable to a sharp edge for cutting tools or weapon points. Intrusive igneous rock: Granite. Quality of durability due to high crystalline quartz and feldspar mineral mix. Also beauty. Harder to work, but a great, long lasting building stone.
What made up the igneous rock?
Igneous rocks can be made of mineral crystals of quartz, feldspar, micas, olivine, amphibole, pyroxene, hornblende, and elements like iron, manganese, calcium, magnesium, silicon, copper, lead, carbon, oxygen, sulfur, hydrogen, and other kinds of rocks
Granite define it?
Granite is defined as "a very hard, granular, crystalline, igneous rock consisting mainly of quartz, mica, and feldspar and often used as a building stone."
How hard is orthoclase feldspar?
On the Mohs Scale of mineral hardness, feldspar is 6 and quartz is 7, so quartz is harder. What does this mean? quartz will scratch feldspar, but feldspar will not scratch quartz.
What is granites origin?
Granite is an intrusive igneous rock and comes from magma. It is a very hard, granular, crystalline rock that is mainly composed of quartz, mica, and feldspar.
Any group of hard rock forming minerals principal constituent of igneous rocks?
feldspar

Is flint igneous or sedimentary?
Flint is a hard, sedimentary cryptocrystalline form of the mineral quartz.

Why is quartz abundant in soils?
Quartz is abundant in soils for three reasons. First, it is an abundant mineral to begin with. Second, it is hard and tough; it doesn't break up and crumble into smaller and smaller pieces very easily. Third, it's more resistant to water and weathering than most other minerals you'll find at the surface of the Earth. Consider granite. It contains quartz, feldspar, and mica. Water eventually degrades the feldspar and mica to clay minerals, but it leaves the quartz behind.
How do you find out what a rocks name is?
If your talking about a mineral, then it's easy. Quartz can be white and see threw and is very hard. Mica is thin, and can be broken into different layers. Hornblende is black and is sort of coal looking. Pink Feldspar is the same a White Feldspar, but just a different color. And Feldspar is light (in weight) and is found everywhere. Literally. If you're talking about Igneous minerals, all igneous rocks are made of different minerals and melted together in a magma chamber and makes magma. Granite is made of Q, M, H, and PF. Obsidian is made of the same minerals, but the lava drifts into the ocean, making it cool quickly, giving it a glassy smooth surface. Volcanic ask is also the same minerals, but looks like grey flour, and you'll know it's ash if there's a volcano near it. Pumice Is again, the sam minerals, but is black and white speckled. This is just a beginner, but you can get more info if you take classes, or are in 6th grad. But that depends on how old you are. Quartz (Q) Pink Feldspar (PF) White Feldspar (WF) Hornblende (H) Mica (M)
