Syncline - Wikipedia Syncline In structural geology, a syncline is a fold with younger layers closer to the center of the structure. A synclinorium ( plural synclinoriums or synclinoria ) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold, termed a synformal syncline ( i.e. a trough ) ; but synclines that point upwards can be found when strata have been overturned and folded ( an antiformal syncline ). Contents 1 Characteristics 2 Notable examples 3 Gallery 4 See also 5 References Characteristics On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold 's center or hinge and with a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate, the structure is a basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building. Notable examples Powder River Basin, Wyoming, US Sideling Hill roadcut along Interstate 68 in western Maryland, US, where the Rockwell Formation and overlying Purslane Sandstone are exposed.
