Abstract
NUMEROUS olivine nodules were recently reported by Sang Lyen1 in a cossyrite phonolite flow from one of the lesser centres peripheral to the Dunedin Volcanic Complex, of Upper Miocene to Lower Pliocene age. The nodules are “… of varying size, widely scattered in the flow. Small nodules, a fraction of an inch across, may be found distributed widely, while larger types are mainly concentrated in the medial layers of the flow …” Blocks up to 20 in. long were found.
