Histoire Ifremer
This chapter presents major oxide and trace element determinations of igneous whole-rock compositions from sites drilled during Leg 60 and electron microprobe mineral and glass analyses of samples from Sites 454 and 458. Interarc basin basalts from the Mariana Trough (Sites 454 and 456) are similar in all respects to depleted mid-ocean ridge basalts. Basaltic andesites and andesites from Site 458 (Mariana fore-arc region) are more depleted than mid-ocean ridge basalts and show different geochemical behavior for Zr-, Hf, and Ti when compared on an extended Coryell- Masuda plot.
