As nouns the difference between calcite and feldspar is that calcite is (geology) a very widely distributed crystalline form of calcium carbonate, caco 3, found as limestone, chalk and marble while feldspar is (mineral) any of a large group of rockforming minerals that, together, make up about 60% of the earths outer crust the feldspars are all aluminum silicates of the alkali metals sodium.
Aug 06, 2011· The key difference between quartz and feldspar is that the major chemical element present in quartz is silicon whereas, in feldspar, it is aluminum.. Quartz and Feldspar are minerals that we can find prominently in the earth''s crust. More than 60% of the earth''s crust consists of Feldspars.

The major differences between quartz and calcite are hardness and cleavage. Quartz is about twice as hard as calcite. Quartz has little or at least very seldom any sort of obvious cleavage ...
Nov 10, 2011· What is the difference between Calcite and Quartz? • Calcite mainly contains calcium carbonate and quartz mainly contains silicon dioxide. • The hardness of quartz is higher than that of calcite. Quartz has Mohs hardness of 7, whereas calcite has Mohs hardness of 3. Therefore, calcite can be scratched by fingernail.
What are two differences between calcite and quartz? ... Feldspar is a mineral group (feldspars) They have a variable composition that gneerally depends on the amount of Ca, Na or K in their ...
Nov 10, 2011· What is the difference between Calcite and Dolomite? • Calcite mainly contains calcium carbonate and dolomite contains calcium magnesium carbonate. Dolomite differs from calcite because of the presence of magnesium. • Calcite reacts quickly with acids and produce carbon dioxide bubbles. But dolomite is weakly reacts with acids producing ...
Jun 18, 2010· Quartz and calcite have many things in common but they also have many differences between them. While Calcite is calcium carbonate, Quartz is silicon dioxide. Quartz is also a combination of oxygen and silicon. First of all, let''s see the difference in their colours. Calcite is colourless, white ...
Slate is composed mainly of clay minerals or micas depending upon the degree of metamorphism to which it has been subjected. The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Slate can also contain abundant quartz and small amounts of feldspar, calcite, pyrite, hematite and other minerals. Color of ...
