Fold axial trace
Webbed-parallel slip is thought to have occurred, such as a fold axial trace. Flexural Slip is best suited for structural settings where sediments are fully lithified at the time of deformation, such as in fold-thrust belts or extensional systems with limestones. In the Weymouth anticline cross-section, Flexural Slip Web> A structure symbol located along the center of the fold has two arrows pointing away from the axial trace. Synclines > In geologic cross section, the fold limbs dip toward the center of the fold (axial plane). The fold points downward and forms the shape of a "U" or "V". > On a geologic map, the layers dip toward the center of the fold (axial ...

WebApr 18, 2024 · If a fracture set has a trend parallel with the fold axial trend (i.e., within 0-15° of the fold axial trace), it is defined as the “axial fracture set.” On the other hand, if a fracture set is perpendicular to the fold axial trend (i.e., 80-90° from the trend of the related fold axis), it is defined as a “cross-axial fracture set.” WebA line drawn through all the hinge points of a fold is called the axial trace of the fold. (It’s also called the hinge trace, which is arguably a better term because the trace has little relation to the fold axis, but most structural geologists use axial trace .)
WebThis exercise introduces new concepts of overturned vs. upright bedding, mapping and interpreting stratigraphic omission and repetition, cleavage and cleavage bedding relationships (including intersection lineations), mapping an axial trace, and mapping and recognizing faults. WebIn 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. A plane …
The fold hinge is the line joining points of maximum curvature on a folded surface. This line may be either straight or curved. The term hinge line has also been used for this feature. A fold surface seen perpendicular to its shortening direction can be divided into hinge and limb portions; the limbs are the flanks of the fold, and the limbs con… The fold hinge is the line joining points of maximum curvature on a folded surface.
