128 - it floats!- probably diatomaceous earth. (Rock specimens: 60, 61). Laterally at this level but not in stratigraphic continuity, outside line of section, are sandy clays with pebbles (Rocks: 62-64). F. ? A series of green clays with small pebbles + spots, looking like porphyry (Rock 56 ), with lenses of coarse sandstone + gravel like that of the Pehuenche. A few scraps of mammal bones found on the clays. Bedding not visible. The lack of continuous exposures, the frequent absence of visible bedding, the highly irregular dips where determinable, and the probable presence of faults, make the determination of a true sequence impossible.
