Parascorodite, FeAsO4.2H2O - a new mineral from Kaňk near Kutná Hora, Czech Republic

Original language description

Parascorodite, a new mineral from Kaňk near Kutná Hora, Central Bohemia, Czech Republic, forms earthy white to white-yellow aggregates associated with scorodite, pitticite, bukovskýite, kaňkite, zýkaite, gypsum, and jarosite, wet chemical analysis gave (in wt%): As2O5 44.45, P2O5 0.84, SO3 1.53, Fe2O3 34.55, Al2O3 0.17, H2O 17.81, totaling 99.95, the simplified chemical formula is FeAsO4 . 2H2O, selected area electron diffraction suggests hexagonal or trigonal symmetry. The extinction symbol is P-c-. Powder X-ray diffraction study has yielded unit-cell parameters a = 8.9327(5) A, c = 9.9391(8) A, V = 686.83 (8) A3, Z = 6. Densities (measured and calculated, respectively) are Dm = 3.213(3) g/cm3 and Dx = 3.212 g/cm3. n(calc) = 1.797.
