Quartz because its harder than calcite and the quartz in thicker.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
No.because calcite is softer then feldspar
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Calcite reacts to acid. The best thing to do to determine if a mineral is calcite is to place a drop of dilute hydrochloric acid on a sample. If the mineral fizzes and carbon dioxide bubbles are produced, the mineral is calcite. Place a drop of dilute hydrochloric acid on the mineral. If it fizzes and carbon dioxide bubbles are produced, the mineral is calcite.
yes.
Sandstone is made mostly from sand-sized quartz particles. On the other hand, limestone is made from finer grains of calcite material.
Many mineral can not scratch Quartz.Remember the mnemonic for Mohs' scale of hardens "The Girls Can Flirt And Other Queer Things Can Do", where the mineral for each first letter is:(softest)TalkGypsumCalciteFluoriteApatiteOrthoclase (Feldspar)QuartsTopazCorundumDiamond(hardest) Thus minerals 1-6 can not scratch quartz.
Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
Sand, usually quartz sand, with the grains cemented together by some other mineral, such as calcite, gypsum, haematite, or clay.
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
A diamond is the only material that cannot be scratched by any other than itself.
Limestone is composed mostly of calcite. Other minerals which may be associated with limestone are are pyrite, dolomite, and quartz, among others.
