Figure F27. A. Photograph of hand specimen of completely serpentinized harzburgite with magmatic dikes (interval 209-1268A-13R-2, 0–8 cm). B. Photomicrograph of one of the magmatic dikes shown in A reveals a talc-amphibole-biotite assemblage. The amphibole (a) in the center of the image is separated from the biotite (b) by talc. The talc-amphibole-biotite vein has talc-rich halos that appear white in hand specimen (Sample 209-1268A-13R-2, 3–6 cm) (plane-polarized light: blue + light gray filters; field of view = 2.75 mm; image 1268A
