Rock Type:

Field Description:

-interlayered sequence of 1 to 2 m conglomerate beds and massive to poorly cross bedded feldspathic lithic arenite
-the sandstones average less than 1 m thick
-minor toumaline is diseminated through out
-the major clast type in the conglomerate is sedimentary
-dominantly siltstone and greywacke
-mafic clasts are rare
-granitics vary from 5 to 15 %
-high level mafic porphyrys represent 5%
-the conglomerate appear to be sheets not trough deposits
-it is apparent that has been a major providence change into a source of lithified sediments
-sample B is lineate conglomerate
