Douglasite
Douglasite is a rare hydrated potassium iron chloride mineral with the chemical formula K2Fe^2⁺Cl4·2H2O. It belongs to the halide class of minerals and is classified under the Strunz system as 3.CJ.20. This mineral typically forms in evaporitic environments and is characterized by its vitreous luster and pale yellow to colorless appearance. It has a relatively low hardness of around 2 to 3 on the Mohs scale and a low density, making it easily distinguishable from other halide minerals. Douglasite is notable for its water content and is typically found in association with other evaporite minerals.

Overview
Douglasite is a rare hydrated potassium iron chloride mineral with the chemical formula K2Fe^2⁺Cl4·2H2O. It belongs to the halide class of minerals and is classified under the Strunz system as 3.CJ.20. This mineral typically forms in evaporitic environments and is characterized by its vitreous luster and pale yellow to colorless appearance. It has a relatively low hardness of around 2 to 3 on the Mohs scale and a low density, making it easily distinguishable from other halide minerals.

Etymology
Douglasite is named after the locality Douglashall, where it was first discovered. The mineral was not officially approved by the IMA but retains its name through grandfathered status.
Geological genesis
Douglasite forms in evaporitic environments where water has evaporated, leaving behind concentrated solutions of soluble salts. It is a halide mineral that typically crystallizes from brine-rich solutions in arid or restricted basins.
Occurrence
Douglasite is known from the type locality Douglashall. It is a rare mineral and has only been reported in a few evaporite deposits worldwide.
How to recognize it
Douglasite can be identified by its low hardness of 2 to 3 on the Mohs scale, its pale yellow to colorless color, and its vitreous luster. It has a low density and typically forms as small, prismatic or tabular crystals. It is often found in evaporite deposits and can be distinguished from other halides by its chemical composition and water content.
Host rocks
Douglasite is typically found in evaporite deposits, often associated with other water-soluble minerals that form in arid or restricted basins where evaporation exceeds precipitation.
Trivia
Douglasite is one of the few halide minerals that contain water in its structure, making it chemically unique. It is also notable for its low hardness and low density, which are uncommon for a halide mineral. Its name is directly derived from the locality where it was first found, Douglashall, and it retains its name through grandfathered IMA status.
