Figure F87. Close-up core photos of typical veined sections. A. Characteristic amphibole vein array from the upper part of the section (interval 176-735B-92R-1, 10-15 cm), showing steeply dipping, parallel veins, often slightly faulted. B. Characteristic smectite veining in the central part of the section (interval 176-735B-133R-7, 84-98 cm) with moderate dips and associated subhorizontal microfracturing. Scale bar in both = 5 cm.
