3 styles of thrust related folds

Keyboard commands:

= turn,

= for-/backward,

= scroll

fault bend fold

fault propagation fold

detachment fold

example of ramp flat geometry

Keyboard commands:

= turn,

= for-/backward,

= scroll

niger delta

source of compressional examples

Keyboard commands:

= turn,

= for-/backward,

= scroll

bude/kilve

fault propagation fold:

as cut off angle decreases....

Keyboard commands:

= turn,

= for-/backward,

= scroll

Log in to view images.

front limb dips increase

fold wavelength increases

fold amplitude decreases

tri shear is a variation of what fold style

Keyboard commands:

= turn,

= for-/backward,

= scroll

fault propagation fold

Trishear example

Keyboard commands:

= turn,

= for-/backward,

= scroll

Tarim basin, China

relative indicator of rate of deformation rate

Keyboard commands:

= turn,

= for-/backward,

= scroll

growth stratigraphy

if one fold in a train amplifies faster what will happen?

Keyboard commands:

= turn,

= for-/backward,

= scroll

strain will be transferred onto that fold, others will fold down/stop

two types of strain accommodation in fold hinges

Keyboard commands:

= turn,

= for-/backward,

= scroll

.

buckle folding of variable stratigraphic layer

Keyboard commands:

= turn,

= for-/backward,

= scroll

increased viscosity ratio=higher wavelength

where does mineralisation occur in fold hinges

in dilational zones
