TESCHEMACHERITE Meaning and
Definition
-
Teschemacherite is a rare mineral that belongs to the carbonate mineral family. With a chemical composition of (NH4)2Mg(SO4)2·6H2O, it contains ammonium, magnesium, sulfur, and water molecules. Named after the American chemist John William Teschemacher, it was first discovered in the mid-1800s in California, United States.
Teschemacherite typically crystallizes in the orthorhombic system, forming prismatic or tabular crystals with a translucent to transparent appearance. It commonly exhibits a pale yellow color, but can also be colorless or have a slight pinkish hue. This mineral possesses a vitreous to silky luster and displays perfect cleavage along two directions, giving it a splintery or fibrous appearance when broken. The hardness of teschemacherite is relatively low, ranging between 2.5 and 3 on the Mohs scale.
As a hydrous sulfate mineral, teschemacherite is often found in evaporite deposits, associated with other minerals such as gypsum, epsomite, and halite. It is typically formed through the evaporation of water in arid regions or the alteration of volcanic sulfur deposits. Due to its scarcity and specific formation conditions, teschemacherite is considered a collector's mineral and has limited economic significance.
In conclusion, teschemacherite is a rare orthorhombic carbonate mineral containing ammonium, magnesium, sulfur, and water molecules. It is notable for its pale yellow color, prismatic or tabular crystal habit, and fibrous or splintery cleavage. Found in evaporite deposits, this mineral has limited industrial applications and is primarily sought after by mineral collectors.
Etymology of TESCHEMACHERITE
The word "teschemacherite" is named after John Teschemacher, an American mineralogist. In 1860, he discovered and described this mineral for the first time. The suffix "-ite" is a common ending used in mineral names to indicate that it is a mineral species.
