If the gravel clasts of a conglomerate are in contact with each other, it is called an orthoconglomerate. Unlike paraconglomerates, orthoconglomerates are typically cross-bedded and often well-cemented and lithified by either calcite , hematite , quartz , or clay.
Orthoconglomerate is a grain supported rock that consists primarily of gravel sized grains and less than 15% matrix grains. If matrix was to be removed from rock types such as paraconglomerate and orthoconglomerate the rock would collapse because the larger grains are supported by the matrix, and without it there is nothing to hold the grains ...

The Sharon conglomerate has no formal type section, [2] although it is named after the town of Sharon, Pennsylvania. One excellent exposure is located in Cuyahoga Valley National Park at "the Ledges," located southeast of the town of Peninsula, Ohio.
In geology, a matrix-supported rock is a sedimentary rock of which a defined majority is the fine-grained matrix as opposed to the clasts (in the case of a conglomerate) or allochems (in the case of a limestone). For a conglomerate, a rock is considered matrix-supported when clasts constitute less than 15% of its volume.
The Uncompahgre Formation is a sequence of quartzite and black phyllite some 2,500 meters (8,200 feet) in thickness. It is exposed in a curving belt from the northwestern to northeastern Needle Mountains with outliers near Ouray and Rico, Colorado.
