PETROLOGIC DATA
Rock Number: 1
-as at 5569, mafic probably basalt, possibly pillowed volcanic at this location the feldspathic locations noted before reached an extreme where they represented almost 50% of rock
-in places the rock is reduced 2 to 3 mm hornblendes, and a fine grain size feldspar matrix
-this appears to be an alteration effect, not a primary feature
-material that is HB in plagioclase quartz is probably part of gabbro at 5572
