A syncline is a fold of rocks with younger rock layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. ... On a geologic map
Development of a mountain range by sedimentation of a geosyncline and isostatic uplifting. This is the "collapse" of the geosyncline. A geosyncline (originally called a geosynclinal) is an obsolete geological concept to explain orogens, which was developed in the late 19th and early 20th centuries, before the theory of plate tectonics was envisaged.
Parallel folds to the north include the Winchester-King's Somborne Syncline, the Stockbridge Anticline and the Micheldever Syncline. As with other nearby folds, the structure is controlled by movement of fault blocks within the Jurassic strata below. [2] The anticline has been explored for hydrocarbons, especially around Cheesefoot Head.
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge.
Sideling Hill is a syncline mountain, in a region of downward-folded rock strata between two upfolded anticlines. The ridge is capped by an erosion-resistant conglomerate and sandstone of Mississippian (early Carboniferous ) geologic age, the Purslane Sandstone of the Pocono Formation .
On the geologic map, "Trenton Gravel" is used to describe most of these sediments. Much of the alluvial sediments that exist here are sand, silt, and clays. [6] The traditional boundary of the coastal plain is the Fall Line. The coastal plain in Pennsylvania was once home to thousands of acres of fresh water tidal marsh.
A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata into a syncline fold. They are geological depressions, the inverse of domes. Elongated structural basins are a type of geological trough.
Baraboo Range in winter Looking east down the range on Wisconsin Highway 78. The Baraboo Range is a mountain range in Columbia County and Sauk County, Wisconsin.Geologically, it is a syncline fold consisting of highly eroded Precambrian metamorphic rock.
