Arrojadite-(KNa)

Arrojadite-(KNa)

Named for Miguel Arrojado Ribeiro Lisboa, a Brazilian geologist. Arrojadite without a suffix now refers to Arrojadite-(KFe), and since a redefinition of the mineral, many resources claim there are more localities for Arrjoadite-(KNa) than are modernly accepted localities. True Arrojadite-(KNa) localities include only in Canada in the Dawson Mining District in Yukon Territory, and in Lombardy, Italy.
