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 ...
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 ...
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

The difference between calcite and limestone is that calcite is a very widely distributed crystalline form of calcium carbonate, caco3, found as limestone, chalk and marble while limestone is an abundant rock of marine and fresh-water sediments; primarily composed of calcite .
Sep 06, 2011· Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of metamorphic rock. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are .
Summary of Key Distinguishing Features. In a given igneous rock, the major light colored minerals will be K-feldspar, plagioclase, quartz, and/or muscovite. Muscovite is easiest because of its silvery clear color and perfect flaky cleavage. If in doubt, use a needle or knife to see if .
