Where Is Limestone Found?
Finding Answers To The Question: Where Is Limestone Found? Limestone is a stunningly beautiful natural stone that has strength, durability, longevity, and diverse uses. It’s one of the most commonly used natural rocks on the planet. While you might think of limestone as a countertop or flooring material, it is also crushed down for construction purposes and used in cement and other materials.
Calcium Carbonate - an overview | ScienceDirect Topics
Commercial calcium carbonate products typically contain at least 95–98% CC, with the remainder being various metal oxides. CC for plastics may be ground from limestone (such as dolomite) or another natural raw source, or chemically precipitated into fine, uniform particles with predictable properties.

Facts About Calcium | Live Science
In its pure elemental state, calcium is a soft, silvery-white alkaline earth metal. It is important to note, however, that calcium is never found in this isolated state in nature, but exists
Calcium in Plants
Calcium is an essential plant nutrient. It is required for various structural roles in the cell wall and meranes, it is a counter‐ion for inorganic and organic anions in the vacuole, and the cytosolic Ca 2+ concentration ([Ca 2+] cyt) is an obligate intracellular messenger coordinating responses to numerous developmental cues and environmental challenges.
