Abstract
Abstract Lavas and dikes in Rarotonga were sampled at 12 sites and are all found to be of reversed polarity. The mean directions of remanence are found to be 223°, + 59°, for samples from the Avatiu Valley and 180°, + 48°, for samples from the Tuoro quarry; the average circular standard deviations are 47° and 20° respectively. Insufficient sampling prevents interpretation in terms of secular variation.
