No Data
Comments:
De Ment make an association between the name collinsite and quercyite a discredited name today (carbonate-rich hydroxylapatite donker than collinsite). Collinsite is sometime associated with scholzite;
Main Activator(s) and spectrum:
Most Common Activator: Organic impurities
No spectrum for the momentComments on activators and spectra:
Collinsite from François Lake, BC, Canada is associated to bitumen which could be the cause of fluorescence.
