Structure type | Strike | Dip | Separation
gneissosity | 261 | 41 |

PETROLOGIC DATA

Rock Number: 1

Rock Type: sandstone
Descriptors:
gneissic
biotite-garnet bearing
Field Description:

-light grey weathering, fairly feldspathic sandstone
-little evidence of MV concentration
-approximately 50% of exposure is pegmatitic intrusion and coarse granitic leel
-SNDS has bleached, gneissic appearance with little continuity to layering
-textures are intrusive rather than anatectic although there has probably been extensive metasomatic alteration of the SNDS
-PGTC material is red, KF rich with no indication of proisterite development
-appear to be a simple swarm probably intruding in advance of a granitic body
