BLOEDITE with HALITE, SODA LAKE, SAN LUIS OBISPO COUNTY, CA, USA (miniature)

Blödite, also known as bloedite, is a hydrated sodium magnesium sulfate mineral characterized by the formula Na₂Mg(SO₄)₂·4H₂O This mineral typically appears clear to yellow, often exhibiting darker shades due to inclusions, and it crystallizes in a monoclinic structure.

The first description of Blödite dates back to 1821, when it was identified in a salt deposit located in Ischler Salzberg, Bad Ischl, Gmunden, Austria. It was named in honor of the German mineralogist and chemist Karl August Blöde (1773-1820).

Blödite can be found globally in evaporitic sedimentary settings, including the Great Salt Lake in Utah.

Halite is also known as "stone salt", NaCl.
