Sometimes it's a complex system of technical terms, such as the specialized language used in medicine or law. In other cases, it's a less-formal system of abbreviations and acronyms. For example, job advertisements frequently use acronyms such as DOE or EOE to streamline their postings. Understanding the meaning of these and other terms can simplify the job-hunting process.
Limestone hills, Cotswolds. The Cotswold hills are made of Oolitic limestone, a type of limestone made up of small round grains. These formed in shallow, warm waters like those found today around Florida and parts of the Caribbean Sea, where calcium carbonate is deposited from sea water due to evaporation.
Sandstone is formed from sediments of small grains, usually quartz. The individual grains may be visible, and can be loosely cemented, often rubbing off in your hand. Limestone usually is composed of finer grained material of calcite origin, such as sea shells, or precipitates of calcite origin.Limestone will effervesce in slightly acidic solutions such as vinegar because of the chemical reaction of calcium carbonate with acid.Sandstones will not have this reaction. think you have it confused, dolomite and limestones are not the same thing: Limestone is composed of calcite or calcium carbonate, CaCO3, and dolostone is composed of dolomi â¦ te or calcium magnesium carbonate, Ca,Mg(CO3).
