Figure F8. Composition of amphiboles in major lithologies according to the classification of Leake et al. (1997), Hole 1256D. A. Calcic amphiboles with CaB ≥ 1.5, (Na + K)A < 0.5, and CaA < 0.5. B. Calcic amphiboles with CaB ≥ 1.5, (Na + K)A ≥ 0.5, and Ti < 0.5. Ca, Na, K = atoms in the structural formula; A, B = crystallographic sites.
