panethite
Sign in to saveAlso known as IMA1966-035
Panethite, chemical formula , is a rare phosphate mineral that was only found in one meteorite on Earth. It was originally found in the Dayton meteorite in Ohio. It is classified as H-M symbol (2/m) with space group of P21/n. It is amber in color. It was named in the honor of Friedrich Adolf Paneth (1887–1958), a German chemist who made many contributions toward the discovery of the origin of the universe, and especially studies of meteorites.

==Structure== Using X-ray diffraction, the unit cell and the space group parameters were determined. The strongest lines of the X-ray were 5.10(6), 3.236(5), 3.007(10), 2.749, 2.710(7) (American Mineralogist, 509). But the error of the cell lengths were relatively high due to twinning and some disorder in the grains examined. Panethite has a monoclinic crystal system with a0=10.18 ±0.01Å, b0=14.90 ±0.02Å, c0=25.87 ±0.03Å and β =91.1˚, and its space group P21/n. Within the error that accompanied the microprobe analysis, the X-ray density was found to be 2.99g/ml.
