lecontite
Sign in to saveLecontite (sodium ammonium sulfate dihydrate, with potassium substituting for some ammonium, typically about a fourth) is a sulfate mineral with the formula (NH4,K)NaSO4·2H2O. It was found by John Lawrence LeConte in Las Piedras Cave in Honduras as a breakdown product of bat guano, including crystals up to an inch long and identified as a separate mineral by W.J. Taylor in 1858. As of 1963 most natural specimens came from the same cave.
