چکیده
Rare sulphate of nickel, retgersite, was identified on the one specimen collected dump Lill shaft, Březové Hory ore district, Příbram (Czech Republic) in 1990s. The consists quartz gangue with dominant millerite and sphalerite. Retgersite forms light blue to blue-green curved fibrous microcrystalline aggregates up 2 mm size vitreous lustre, growing surface small outer vugs supergene altered gangue. by PXRD its refined unit-cell parameters (for tetragonal space group P41212) are: a 6.7838(2) Å, c 18.2951(8) Å V 841.94(4) Å3. Results semiquantitative chemical analysis (EDS) as well vibrational spectra (Raman, infrared) including their tentative assignments are also given. studied retgersite formed (sub)recent weathering primary nickel mineralisation (mostly millerite) mine conditions.
