Fluorescence of GoldquarryiteHide

Not fluorescent.

Other InformationHide

IR Spectrum:
IR absorption shows absorption bands for H2O. A strong intensity band at 3293 cm-1 with a shoulder at 3123 cm-1 due to O-H stretching. A medium intensity band at 1665 cm-1 due to H-O-H bending. Also a very strong band at 1042 cm-1 and a medium strong band at 1143 cm-1 due to fundamental stretching for phosphate.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
