PETROLOGIC DATA

Rock Number: 1

Rock Type: conglomerate
Field Description:

-entire shoreline for north .5 of island is a uniform section of cross bedded sandstones and trough conglomerate deposits
-units alternate regularly at about 50 cm sands and 30 cm conglomerate
-schistocity is at a high angle to bedding
-clast elongation is at the S surface intersection
-no reliable topping direction
-the change in stratigraphy occurs abruptly at a fault bringing the sand and conglomerate unit into juxtaposition with white quartz rich festooned sand beds
-festooned sands have rare pebble lags and scattered calc-silicate horizons
-there appears to be a slight angular relationship at the fault between bedding directions in the two units
