Size and Shape of Rock-fragments in Tuscarora Scree, Fishing Creek, Lamar, Central Pennsylvania

J. C. Griffiths

ABSTRACT

Variation in size, size-sorting, and axial proportions of fragments from a Tuscarora Scree in Central Pennsylvania is similar to variation in pebbles and quartz grains from other sedimentary deposits. The largest source of variation occurs among fragments and no pattern of variation is evident over the small area sampled. This is in accord with expectations on the basis of sampling sediments which lie near their source and have suffered little selective sorting.
