Is a member of the mineral group that has silicon and oxygen in it's chemical compound.
The real question is what type of rock doesn't contain aluminum sillicates and other mineralsBut if you really want the answer I suppose I will tell you. It's feldspar. Happy?
Neptune's atmosphere is composed of hydrogen, helium, methane and ammonia. Its blue color is from the methane. It is surrounded by huge swirls of clouds and storms. There is a very faint collection of rings made up of pieces of material as big as cars and trucks. Neptune's core is thought to be made up of liquid rock that gradually turns into an ocean made up of hydrogen, helium, ammonia, methane and water.
Sillicates are what make horsetail a scratchy tool.Specifically, the plant in question (Equisetumspp) includes the designation "scouring-rush" among its common names. It is reminiscent of rushes in its leaflessness. Its straight stems serve as effective cleaning and scouring tools since their abrasiveness is due to their coating of anionic silicon compounds.
