STRUCTURAL DATA

Planar Structures:
Structure type | Strike | Dip | Separation
schistosity | 79 | 49 |
fault | 246 | 75 |

Dikes and Sills:
Rock Number | Type | Width (m) | Strike | Dip
0 | pegmatite | 0.25 | 201 | 49

Linear Structures
Type | Plunge | Azimuth
microcrenulation | 71 | 306
rodding | 0 | 0

Rodding is stretching and rolling of augen.
Pegmatites are quartz-plagioclase-microcline with minor biotite - some are sheared out almost completely.
