Carnallite
First discovered in 1856, this mineral was named after Rudolf von Carnall (1804-1874), a Prussian mining engineer. It is found in saline marine deposits by action of high potash fluids such as deposits in Stassfurt, Germany and eastern New Mexico. It is a source of potassium and magnesium.
Carnallite (also carnalite) is an evaporite mineral, a hydrated potassium magnesium chloride with formula KMgCl3·6(H2O). It is variably colored yellow to white, reddish, and sometimes colorless or blue. It is usually massive to fibrous with rare pseudohexagonal orthorhombic crystals. The mineral is deliquescent (absorbs moisture from the surrounding air) and specimens must be stored in an airtight container.
