Salt from the Dead Sea
This salt is a unique mixture formed in one of the most chemically extreme environments on Earth. The Dead Sea is a landlocked hypersaline lake in the Jordan Rift Valley, where intense heat and evaporation have concentrated dissolved minerals over immense spans of time. This process produces a salt that is fundamentally different from ordinary sea salt in both composition and structure.
The Dead Sea lies at ~440 meters below sea level (and dropping), Earth’s lowest exposed land surface. The sea lies on a major tectonic boundary between the African and Arabian plates. With no outlet, the lake loses water almost entirely through evaporation, driving salinity to ~34%—ten times that of the ocean. As a result, Dead Sea salt is only ~30% sodium chloride, instead dominated by magnesium, calcium, potassium, and bromide salts.
The water’s density reaches ~1.24 kg per liter, allowing effortless floating and preventing most life from surviving. Mineral layers here record climatic shifts across the Middle East for millions of years, preserving a rare chemical archive of deep geologic and human history.
