Gabbronite

Old discredited name, has been refered to both Scapolite and Nepheline. [Clark, 1993, 249 - "Hey's Mineral Index - 3rd Edition"]. Schumacher (1801) introduced the name gabbronit [gabbronite] as a new mineral from both Kjenlie Mines (Kenlie) in Arendal, Norway and Stavern (Fredriksvärn)[Friedrichsvärn], Norway. The "gabbronite" from Kjenlie was probably a blue-greyish altered scapolite and the "gabbronite" from Stavern (Frediksvärn) was probably an altered nepheline.
