gneissosity 34 73

-as before

PETROLOGIC DATA

Rock Number: 1

Rock Type: two component schlieric gneiss - intimate mixture of 2 major units

Field Description:

TCSG:
this code indicates a rock composed of gneissic tnlt and grey granodiorite to tnlt intermixed and sheared to a two component schlieric gneiss with variable degrees of shearing, cataclasis and mylonitization. In general the unlt is massive to weakly porphyritic with pre-existing fabrics and some preservation of early granitic lit or mobilizate(?). The grey grdr is significantly younger and less injected.
-internal fabric of TNLT has a large number of high amplitude isoclinal folds.
