Detailed explanation-1: -An anticline is a fold that is convex upward, and a syncline is a fold that is concave upward. An anticlinorium is a large anticline on which minor folds are superimposed, and a synclinorium is a large syncline on which minor folds are superimposed.
Detailed explanation-2: -An upward fold is called an anticline, while a downward fold is called a syncline. In many areas it’s common to find a series of anticlines and synclines (as in Figure 12.5), although some sequences of rocks are folded into a single anticline or syncline.
Detailed explanation-3: -An anticline is a structural trap created through the folding of rock strata into an arch-like shape. The rock deposits in an anticlinal trap were formerly located down horizontally and then Earth movement created it to fold into an arch-like shape termed as an anticline.
Detailed explanation-4: -Anticline. An anticline is a fold that arches upward. The rocks dip away from the center of the fold (Figure below). The oldest rocks are found at the center of an anticline.
Detailed explanation-5: -anticline in British English (ˈæntɪˌklaɪn ) noun. a formation of stratified rock raised up, by folding, into a broad arch so that the strata slope down on both sides from a common crest.
