STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
cataclastic foliation | 303 | 62 |
-one feature that remains inconsistant with the apparent age relation is that the fabric is generally more obvious in younger GRNT than grey porphyry
-this may just be reflection of coarser grain size and uniform grain size distribution
PETROLOGIC DATA
Rock Number: 1
-mottled pink and white younger granite
-30 % quartz variable 3 to 5 % microcline phenocrysts
-MG significantly higher than grey porphyry
-the only real difference between grey porphyry and this unit is a more uniform grain size distribution, coarser groundmass, higher quartz, and MG and fewer phenocrysts.
