PETROLOGIC DATA
Rock Number: 1
-charcoal grey porphyry with MC phenocrysts upto 8 mm
-phenos euhedral to subhedral
-fabric less intense so phenos aren't augened
-contradictory evidence for age relationship-FDPP seems to both intrude and be included in GRDR
-my gut feeling is that the fabric is far less intense in the FPPP than the GRDR so it intrudes the GRDR but later cataclasis scrambles the contact relations
Rock Number: 2
-as previous station except possibly less mafic-texturally they look the same
-probably as inclusions in FPPP
