In this case the folds found within the Miocene sediments have been interpreted as extensional folding in the form of the ramp anticlines and drag folds. |
Large-scale geological structures including anticlines, synclines, thrusts and faults formed during the Caledonian Orogeny typically trend in a SW-NE direction. |
Following the intrusion of basic dykes in the late Palacocene, the whole of the post-Zechstein succession was gently folded into a series of major synclines and anticlines. |
In the process, domes, cavities, faults and anticlines were created. |
It has been previously reported that because of extension of the outer arc of such anticlines, graben form above their crests. |
Bozkurt mainly provides a short, but incomplete, summary of previous work on field characteristics of extensional folds, including rollover anticlines. |
