The yellow lines represent the bedding while the red lines represent the supposed fault zone, is it strike-slip or thrust fault affect the the section in carbonate rocks.....
Might be a plunging fold with top chopped off. check the relative position of the beds older vs younger
It is difficult to judge from the photograph, but what it reminds me of are the remnants of a small-scale palaeo sinter terrace system: carbonates were deposited in arcs delimiting small water basins.
Yes - difficult to see. Probably something tectonic, but has also some similarities to water escape structures. (I can´t see from the photo if the structure is "pre- or post-lithification".)
It looks like a dewatering structure. But it is difficult to decide from a photo.
I think it is deformation with folding. In the foreground and towards the left upper corner you see two more folds, The one in the upper left part of the photo seems to die out downwards and may be due to some pre-lithification movement.
Gravity flow with tectonics and water escape structure ... ? (I can´t see any evidence that it could be a clastic dike, from what is visible in the photo.)
it's better to get a regional photo from this place because in this case we need to see the structure in wide zone of deformation for making decision
Dear Pooria, It could be as your explanation, but there is shearing.....
we called such a kink- or knick fold. Anticline sure, brittle deformation with broken hinge. Fracturing in contractional realm, fault (displacement) not excluded.
best curved fold hinge is in the lowermost part of your vote, where marls are more bended, whereas the limestones above are fractured
Agreed, brittle deformation inside the nucleous of an anticline, evolved in the final phase of folding. Good explanation given by Helmut. Adding that probably the movement is anti-clockwise oblique along faults; also that plunge of the fold could indicates that 1st order kinematics could be extensional, or late-tilting. Need more elements to check.
It is reasonable explanation given by Helmut and also Sidnei....thanks
I would suggest that It is better to understand the regional stratigraphy and tectonic history (if possible) before interpreting local structures. In a foreland basin or any tectonic active areas, first for all, the marginal sedimentary deposits are occasionally slid and slumped down-slope undergoing a wide range of style and scale of syn- and/or after- depositional deformation. The structures of these deformed deposits will definitely further be complicated by tectonic thrusting and folding during being incorporated into thrust belts. The structure showed in the photo may probably be formed as described above. I would emphasize again, It is better to understand the regional stratigraphy and tectonic history first.
