Landform: Anticlinal hills or Jura-type relief |
2. Fomative conditions: Primary folds at various stages of erosion. 3. Description: Folded surfaces that directly mirror the underlying geological structures. |
|
|
Landform: Inverted relief |
2. Formative conditions: Primary folds at various stages of erosion. 3. Description: Structural lows occupy high areas (i.e. perched syncline) and structural highs occupy low areas (i.e.anticlinal valley). |
|
|
Landform: Planated relief |
2. Formative conditions: Primary folds at various stages of erosion. 3. Description: High-eroded folds. |
|
|
Landform: Appalachian-type relief |
2. Formative conditions: Primary folds at various stages of erosion. 3. Description: Planated relief that is uplifted and dissected, leaving vestiges of plains high in relief. |
|
|
Landform: Ridge and valley topography |
2. Formative conditions: Differential erosion of folded sedimentary sequences. 3. Description: Terrain with ridges and valleys generally following the strike of the beds and so the pattern of folding includes breached anticlines and domes. |
|
|
Landform: Cuesta |
2. Formative conditions: Differential erosion of folded sedimentary sequences. 3. Description: Ridge formed in gently dipping strata with an assymetrical cross-section of escarpment and dip-slope. |
|
|
Landform: Homoclinal ridge and strike ridge. |
2. Formative conditions: Differential erosion of folded sedimentary sequences. 3. Description: Ridge formed in moderately dipping strata with just about asymmetrical cross section. |
|
|
Landform: Hogback |
2. Formative conditions: Differential erosion of folded sedimentary sequences. 3. Description: Ridge formed in steeply dipping strata with symmetrical cross section. |
|
|
Landform: Escarpment (scarp face, scarp slope) |
2. Formative conditions: Differential erosion of folded sedimentary sequences. 3. Description: The side of the ridge that cuts across strata, picks out lithological variations in strata. |
|
|
Landform: Dip-slope |
2. Formative description: Differential erosion of folded sedimentary sequences. 3. Description: The side of a ridge that accords with the dip of the strata. |
|
|
Landform: Flatiron (revet crag) |
2. Formative conditions: Differential erosion of sedimentary sequences. 3. Description: A roughly triangular facet produced by regularly spaced streams eating into the dip-slope or ridge (especially a cuesta or homoclinal ridge). |
