Category:Syncline

In geology, a syncline is a fold in the layers of the earth which typically form an indentation or trough in the earth's surface, such as where one would find a valley. Yet syncline can also describe the layered formation that points upwards when strata have been overturned and folded or if the fold pattern makes a basin, even though the earth's surface is cone-shaped.
