STRUCTURAL DATA

-outcrop 40 m x 60 m is mainly granite
-E-W joints are spaced 2 to 3 m apart
-cleavage in foliated plane is not strong with most fractures in pegmatite seams 2 m apart
-weak horizons-subhorizon joints at .5 to 1 m spacing

PETROLOGIC DATA

Rock Number: 1

Rock Type: granite
Descriptors:
schlieric or schlieren present
garnet-biotite bearing
Field Description:

-white weathering with samll pink hematitic spots, med. grained peristerite granite
-highly variable texture for?? equi-homo GRNT to sacc. aplite and irregular peg. patches
-majority of rock is equigran. GRNT
-garnet is abundant randomly distributed up to 1 cm size
-strong BO foliation
-majority of aplite peg. in the foliation plane 6T slightly crushed and elongate in the foliation plane
-consistant augenment of mineralogy of fabric may indicate crystallization in a directed stress field
-aplitic units and aplitic margins on pegmatites have layered garnet-horizons
-on first impression, fracture pattern and degree of homogen. is attractive and outcrop area is probably adequate
-the fact that thre is a Hurdo pole in the middle might be determinental
-cleavage should be evaluated for estecties and bearing strengths
