| Abstract | Sixty-two samples from five volcanic centres (Ember Ridge, Mount Fee, Slag Hill, Ring Mountain, and Little Ring Mountain) were collected as part of a preliminary petrological investigation of the Mount
Cayley volcanic field. The sampled deposits are flows and domes, and many show features indicative of ice contact during eruption (e.g. abundant glass, fine-scale jointing). Mineralogically, the samples range from andesite to rhyodacite, and chemi-
cally, the rocks span a range from andesite to dacite. Glassy samples are abundant, with glass contents as high as 70%. |
