STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 51 63
fault 346 80 dextral
fault 296 85 dextral

-conjugate shear sets indicte maximum compression at 151 degree which gives an extension component at 61 degree which is 10 degrees to plane of movement
-this is confirmed by a 061 en echelon ship cleavage that is the actual method of stepwise slip aggregate in the 051 plane

PETROLOGIC DATA

Rock Number: 1

Rock Type: MCGS

Field Description:

-back into the main Whiskey Jack zone with heavy shearing and all kinds of intrusions of many ages.
-I can't even be sure if core?? of the inclusion(?)/baudins(?) aren't really sediments
-appears to have old grey porphyry GRDR and young grey GRDR plus many peg. veins.
-Sample a--leuce GRDR matrix, Sample b--old GRDR porphyry
