ANTIFORMAL AND SYNFORMAL ANTICLINES AND SYNCLINES
网页Antiformal anticline: a second generation antiformal fold on the normal limb of a recumbent fold and containing oldest rocks in the core; Synformal Syncline: a second generation synformal fold on the normal limb of a recumbent fold and containing youngest rocks in …
Syncline - Wikipedia
网页Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline).
1.5: Folds - Geosciences LibreTexts
网页If the younging direction is towards the inside of the fold, then the fold is a syncline. If the younging direction is away from the inside of the fold, then the fold is an anticline . In areas of mild deformation like the Rocky Mountain foothills, where the rocks are regionally the right way up, anticlines are antiforms; the terms can be used ...

网页Synclines are typically a downward fold, termed a synformal syncline (i.e. a trough); but synclines that point upwards, or perched, can be found when strata have been overturned and folded (an antiformal syncline).

Antiform - an overview | ScienceDirect Topics
网页In a syncline the beds young, that is get younger, towards the fold’s core; in an anticline the beds young away from the core of the fold. Either type can be antiformal or synformal.
Folds - SpringerLink
网页If the ages of the rocks of an antiform or of a synform are known, these structures can be named as antiformal syncline or a synformal anticline. In an antiformal syncline (Fig. 8.29c ), the strata dip away from the axis of the fold and the rocks at the core are younger; the structure can thus be described as a downward-facing syncline .
12.2 Folding – Physical Geology – 2nd Edition
网页An upward fold is called an anticline (or, more accurately, an antiform if we don’t know if the beds have been overturned or not), while a downward fold is called a syncline, (or a synform if we don’t if the beds have been overturned). In many areas it’s common to find a series of antiforms and synforms (as in Figure 12.5), although some ...
Syncline - AAPG Wiki
网页2019年3月21日 · So in order words, a syncline is identified by the younger rocks at it’s core. In folds, crests and troughs are usually firstly referred to as synforms and antiforms until the age of the rocks are known.
