Conglomerate Rock and the Flood
Conglomerate is a coarse-grained clastic sedimentary rock, or a rock that has been rolled around by waves or currents and implies catastrophic deposition, further giving great evidence of the Genesis Flood. Conglomerates have a mixture or variety of rounded grains sizes (at least 2 millimeters in diameter) from gravel-sized clasts to pebbles, cobbles and boulders with a fine-grained matrix glued in between the larger grains. This matrix can be composed of calcium carbonate, iron oxide, silica, or clay. Because of the large size of grains found in conglomerate rock, strong surges of water and high-energy environments are needed to carry these grains and deposit them. These strong surges of water and high-energy environments could easily be explained by the floodwaters of the Genesis Flood. The high-energy environment would also be needed to produce the rounded grains. While many smaller and medium sized conglomerate deposits are found in braided river channels or beach environments, thick and extensive sediment deposits in the world have been found that contain conglomerate rock. Evolutionists believe that conglomerate rock forms in braided streams over millions of years. However, conglomerate rock is not forming today in braided river systems. Therefore, evolutionists use "evidence" that cannot be observed and use their "millions of years" disguise to explain the formation of conglomerate rock and other sedimentary rocks. The 200-foot thick Shinarump Conglomerate of the Chinle formation of the Colorado Plateau is a very large scale deposit that extends for at least 100,000 square miles in extent (USGS) and ranges from 50 to 350 feet thick. To find conglomerate rock in such large scale deposits would imply a large scale event, such as the Genesis Flood to create these massive formations.
