Figure F20. Localized formation of tremolite (Tr), chlorite (Chl), and talc (Tc) between olivine (Ol) and plagioclase (Pl) (Thin Section 97; Sample 345-U1415P-3R-1, 120–123 cm). This coronitic assemblage occurs locally within samples and is commonly distributed heterogeneously across individual olivine grains. Much of the olivine in this photomicrograph lacks the coronitic assemblage. Srp = serpentine. A. Plane-polarized light. B. Under crossed polars.
