Initial Reports Volume 187 Chapter 3, Table T5. Glass and whole-rock major and trace element compositions of basalts, Site 1152. Notes: Data tables for every site report the XRF major element analysis from two fused disks and trace element analyses from a single pressed-powder pellet, all made from splits of a single sample powder. A split of the same whole-rock powder was also analyzed by ICP-AES for major and trace elements. Reported ICP-AES results are repeated analyses of a single solution measured two or three times during a run. ICP-AES whole-rock data are suspect for Site 1152. However, the glasses have been sampled, dissolved, and analyzed a second time and are considered reliable. * = SiO2 by difference for ICP-AES; LOI = loss on ignition.
