Planar Structures:
Structure type | Strike | Dip | Separation
fault | 201 | 87 |

-fault contact between conglomerates and bedded lithic arenite
-walking the section from 5437 to 5438 it is apparent there are a large number of fault in the section and the stratigraphy has a condensed look

PETROLOGIC DATA

Rock Number: 1

Rock Type: arenite
Descriptors:
lithic
Field Description:

-sandstone beds appeared in the chaotic conglomerate far too high in the section
-deformation is high and the chaotic unit seems to have shrunk by almost half
-there are numerous mylonite with breccia zones and mylonites with quartz vein cores and hornblende alteration
-this may be the case for the amphibolite at 5434
-faults are generally in the foliation bedding plane
