PETROLOGIC DATA
Rock Number: 1
-homo equi. grey GRDR
-contains numerous inclusions of ampb.
-not really recognizable as a unit encountered before unless it is a less sheared example of the cata GRDR (rock 2 6284)
Rock Number: 2
-various ampb inclusions-most are just fine grained black cracks and were probably basalts, but one large inclusion (sample) was probably a med. grained HB gabbro
-extensivly intruded by rock 2 and then folded and sheared
Rock Number: 3
-many 5 to 20 cm dikes parallel to foliation of the younger GR bearing white GRDR
Mineral | Abundance (%) |

Rock Number: 4
-thin dikes of highly sheared aplite-movement of shear planes seems to be preferential to zones invaded by aplitic as they are more sheared than the bulk of the outcrop
