Langban - Exhalative Sedimentary Deposit

• Chemical, mineralogical, and isotope analyses of hausmannite, braunite, and hematite ores from Laangban, Sweden, show that the precursor of this deposit has several similarities in its mineralogy, chemistry, and oxidation state with many deposits of Devonian and Recent ages, such as some deposits in Kazakhstan, in the Red Sea hot brine depressions, and in the East Pacific Rise. Possibly Rammelsberg, Meggen, Franklin Furnace, and Sterling Hill also belong to this type of deposit, for which an exhalative-sedimentary origin is proposed.
