Abstract

Identifies two kinds of breccia; type A limestone breccia (LBA) and type B limestone breccia (LBB). These rocks are characterized by polymictic components, wide-ranging sizes, poor sorting, dense packing and disorganized fabrics of shallow-marine limestone clasts and generally small proportions of a matrix. Decrease in clast-size and increase of abraded clasts from the LBB to the limestone sandstone imply a depositional progression from the LBB through the limestone debris-crowded rock and limestone conglomerate to the limestone sandstone. -from Authors
