TRACE ELEMENT AND ISOTOPIC VARIATIONS IN A ZONED PLUTON AND ASSOCIATED VOLCANIC ROCKS, UNALASKA ISLAND, ALASKA: A MODEL FOR FRACTIONATION IN THE ALEUTIAN CALCALKALINE SUITE

Perfit, M. R., Brueckner, H., Lawrence, J. R., and Kay, R. W., 1980, Trace element and isotopic variations in a zoned pluton and associated volcanic rocks, Unalaska Island, Alaska: a model for fractionation in the Aleutian calcalkaline suite: Contributions to Mineralogy and Petrology, v. 73, n. 1, p. 69-87.

DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.

64: Major and trace element abundances: Captains Bay pluton, Unalaska

* FeO" = Total Fe ad Fe2+; Sample 12: Andesite from Pakushin cone Unalaska; 12: Andesite Unalaska formation; 14: Dike in Unalaska formation; 15: Basalt, Umnak Is. (Kay, 1977): short dash means not analyzed *

65: Rare earth element and barium abundances in plutonic rocks, Unalaska Island

* (super a) Determined by spark-source mass-spectrometry (ANU), all others done by isotope dilution (L.D.G.O.); Ba by XRF. All values in ppm. * Interpolated value *

66: Strontium and oxygen isotopic ratios, Captains Bay pluton

* (super a) "K"=K2O/K2O + Na2O (super b) Sample measured for O18/O16 (super c) Analysis by M. Perfit (A.N.U.) measured NBS987-0.71032, all others by H. Brueckner, measured NBS987-=071039. All samples normalized to NBS987-0.71022. sigma=1 standard deviation *
