Occurrences of Rhiinite in Alkalic Lavas of the McMurdo Volcanic Group, Antarctica, and Dunedin Volcano ' New Zealand

Occurrences of rhijnite are reported in alkalic lavas of the McMurdo Volcanic Group (Hut Point Peninsula, Antarctica) and Dunedin Volcano (New Zealand). Electron microprobe analyses increase the range of composition reported for rhiinite, with the Antarctic examples having higher TiOr, and the Duned...

Description
Summary:Occurrences of rhijnite are reported in alkalic lavas of the McMurdo Volcanic Group (Hut Point Peninsula, Antarctica) and Dunedin Volcano (New Zealand). Electron microprobe analyses increase the range of composition reported for rhiinite, with the Antarctic examples having higher TiOr, and the Dunedin example higher NarO than other terrestrial rhiinites' Deteciabli quantities of CrzOs (average 0.1 I percent) and NiO (0.06 percent) are recorded for the first time. The rhdnite shows no compositional variation toward aenigmatite.
