| 释义 | callainiten. Mineralogy. Now rare or disused.   A green mineral discovered at an archaeological site in Brittany, France, identified with Pliny's callais (turquoise) but later shown to be a mixture of turquoise and wavellite. ΚΠ 1868    J. D. Dana Syst. Mineral. 		(ed. 5)	 572  				Yet, as this identity is not established, the name callainite is better than Pliny's name unmodified. 1883    Proc. Royal Irish Acad.: Sci. 3 552  				Variscite..is clearly identical with the callainite of Damour, a mineral the provenance of which is unknown. 1942    Amer. Jrnl. Sci. 240 654  				Callainite, from Montebras, France, produces a pattern that can be satisfactorily accounted for only by assuming a mixture of wavellite and turquoise.
