Trace element variation in the volcanic rocks of Adak and Umnak Islands of the Aleutian Arc
Walker, A. T. III., 1974, Trace element variation in the volcanic rocks of Adak and Umnak Islands of the Aleutian Arc: Columbia University unpublished M.S. thesis, 39 p.


Data tables:
113: Analyses of the Aleutian samples (Concentrations are in ppm except for wt. % TiO2) * (1) The lead analyses are from S. Sun (1973). (2) Analysis by R. Kay (UM18 and UM5). (3) The number after the 1A prefix are the location numbers of Byers (1959). Major element analyses and modal composition are given in Byers. *
114: Parameters used in partial melting calculations for successful source compositions * (1) The chondrite normalized concentrations of the calculated liquids have to be raised by these enrichment factors to bring them up to those of the measured andesites. *
115: Sample description (samples collected by R. Kay)
