limestone | Characteristics, Formation, Texture, Uses ...

Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

A Very Simple Metamorphic Classification

 · Metamorphism is the alteration of a preexisting rock (the parent rock) due to heat and pressure caused by burial in the earth.The parent rock must adapt to the new conditions and it does so by changing mineral composition and texture. These rocks with new texture and composition are metamorphic rocks.

What Is the Chemical Composition of Salt?

 · The chemical composition of table salt is NaCl. Table salt is a combination of sodium and chlorine, which form ionic bonds. Table salt is made up of ions. Ions are formed by atoms gaining or losing electrons, which causes the atoms to be positively or negatively charged. In the case of table salt, sodium loses one electron, while chlorine gains ...
