![]() ![]() In very young landscapes it might, but generally how a syncline is expressed depends on the rocks. In other words, a syncline does not necessarily create a valley. An interesting fact of synclines is that they can be as small as a hand specimen, and that the geologic structure does not much affect the topography. The younger rocks are generally found on the inside of the fold. The largest oilfields occur in large, gentle anticlines in thick sedimentary rock layers.Ī syncline is a fold structure in which the sides of the fold slope together. The rock beds trap rising hydrocarbon fluids, allowing oil and gas to build up in the pore space of the anticline rocks. Deep underground, anticlines are highly desired by petroleum prospectors. The younger rocks are generally found on the outside of the fold. ![]() Within these ridges and valleys are two different types of rock folds, anticlines and synclines.Īn anticline is a fold structure in which the sides of the fold slope apart. They are the remnants of an ancient fold-and-thrust belt. These mountains are characterized by long, even ridges, with long, continuous valleys in between. The eastern region of West Virginia lies in is referred to as the Ridge and Valley Appalachians. Along Route 39 just southeast of Marlinton, West Virginia and on the banks of Knapps Creek is a truly fascinating geological formation…Devil’s Backbone. ![]()
