Massanutten Mountain is a synclinal ridge in the Ridge-and-Valley Appalachians, located in the U.S. state of Virginia. Image displaying the topographical differences between two roughly parallel ridges along Virginia's western border: one is the backbone of Shenandoah National Park (right), and the other is Massanutten Mountain (middle/left).
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. [1] Synclines are typically a downward fold (synform), termed a synformal syncline (i ...
Southland Syncline. The parallel strike ridges of The Catlins, which form part of the syncline, can clearly be seen running from northwest to southeast in the upper part of this image. The Southland Syncline is a major geological structure located in the Southland Region of New Zealand's South Island. The syncline folds the Mesozoic greywackes ...
Sideling Hill. Sideling Hill, also Side Long Hill, [1] is a long, steep, narrow mountain ridge in the Ridge-and-Valley (or Allegheny Mountains) physiographic province of the Appalachian Mountains, located in Washington County in western Maryland and adjacent West Virginia and Pennsylvania, USA. The highest point on the ridge is Fisher Point, at ...
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.
The Vindhyas do not form a single range in the proper geological sense: the hills collectively known as the Vindhyas do not lie along an anticlinal or synclinal ridge. [7] The Vindhya range is actually a group of discontinuous chain of mountain ridges, hill ranges, highlands and plateau escarpments. The term "Vindhyas" is defined by convention ...
Note the man standing in front of the formation, for scale. New Jersey, U.S. 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 ...
The southernmost ridge of the Yakima Fold Belt is the Columbia Hills on the north side of the Columbia River. The pattern of folding continues with the Dalles-Umatilla Syncline just south of the Columbia River, and further into Oregon with the Blue Mountains anticline, which approximately parallels the Klamath-Blue Mountain Lineament that marks ...
