Svabite from
Mill site dump, Franklin Mine, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA

Locality type:Mine Dump
Classification
Species:Svabite
Formula:Ca5(AsO4)3F
Comments:The cited informal list was circulated was partly based on traditional identifications. The "svabite" reported by Palache (1935) was annotated: "The analysis yields a rather poor molecular ratio for an apatite but is unmistakably that of a member of the apatite group, as confirmed by the crystallographic character." The analysis for fluorine, coupled with the calculation of O = F, ambiguously places the recalculated composition at the almost perfectly median boundary of the johnbaumite-svabite series. It is evident that johnbaumite named by Dunn, Donald Peacor, and N. Newberry in 1980 superseded previous svabite reports. Dunn (1995) declared that there were no known chemical analyses for Franklin Mining District svabite. Purported "analyzed" svabite specimens are sometimes offered for sale, but there is never a genuine chemical analysis provided.
Confirmation
Validity:Erroneously Reported
