Section 647A-71R-4, greenish gray (5G5/1) with very rare vesicles 1 mm in diameter which are partly filled with calcite. Very few altered veins, frequent horizontal veins up to 3 mm thick. A few vertical veins are present with occasional veins up to 1 mm thick. Both types are filled with: a. calcite (dominant) b. chlorite (abundant) c. pyrite (common). Thirty-one horizontal or almost horizontal fractures (veins filled). One to two nearly vertical fractures, rest see comments.         With scattered < 1 mm vesicles filled with chlorite and calcite. The most striking feature is stockwork veins of calcite and chlorite which are < 5 mm wide. The rocks are greenish gray (5G 5/1). No obvious alteration is observed. This unit is probably part of a thin flow because it is so finely crystalline. No salvages are present. Fracture: Some of which are filled (veins). Grain size coarsens downward.

Cross-cutting vein breaks through top, which has a botryoidal, laminated crust, 0.1-0.5 mm thick. Top 1 cm seems to be a chilled margin. This unit is probably a flow, with original glassy top. Large fragments in Unit 1 are probably flow-top breccia. Crystallinity: Aphanitic to finely crystalline and variolitic. Top could be pillow salvage.

Abundant: pyrite a) as few mm grains in thick veins. b) dominant in some smaller veins. Section 74R-4: H=21; SH=2. Two of the latter complex with smaller "apophyses". Chlorite and serpentine dominant in veins. Pyrite often concentrated in few mm grains in bigger veins. Fractures are produced by drilling and are almost entirely located in veins.
