Figure F10. Histogram of the proportion of rock types analyzed from Hole 1105A, based on modal analysis. Olivine gabbros and gabbros are indicated as oxide-free (<0.1 mod% oxide), oxide bearing (0.1–4.9 mod% oxide), or oxide gabbros and oxide olivine gabbros (>5 mod% oxide). The naming of oxide gabbros and oxide olivine gabbros is in accordance to suggestions of the IUGS in using modifiers for plutonic rocks (i.e., accessory phases should be >5% modal abundance). Oxide-bearing was used for all rocks containing some oxides, but <5% oxides, in order to allow some comparison terminology with Leg 176 terminology in distinguishing between rocks with or without magmatic oxides. Note different terminology was used in Hole 1105A (Thy, Chap. 3, this volume) and in Hole 735B (Dick, Natland, Miller, et al., 1999) descriptions (also see the Leg 176 and 179 "Explanatory Notes" chapters, Shipboard Scientific Party, 1999a, 1999b).
