differences between feldspar and calcite

Calcite vs Feldspar - What's the difference? WikiDiff

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 rock-forming minerals that, together, make up about 60% of the earth's outer crust the feldspars are all aluminum silicates of the alkali metals sodium ...

calcite mineral Britannica

Between 60 and 70 elements have been recorded in minor or trace amounts in limestone analyses. Some of these elements may occur as substitutions within calcite; others seem more likely to represent minor constituents, such as clay minerals, within the analyzed rocks.. The chemical composition of calcite is responsible for the test that is widely used to identify it, especially in the field.
