folds/faults
3 styles of thrust related folds
fault bend fold
fault propagation fold
detachment fold
example of ramp flat geometry
niger delta
source of compressional examples
bude/kilve
fault propagation fold:
as cut off angle decreases....
front limb dips increase
fold wavelength increases
fold amplitude decreases
tri shear is a variation of what fold style
fault propagation fold
Trishear example
Tarim basin, China
relative indicator of rate of deformation rate
growth stratigraphy
if one fold in a train amplifies faster what will happen?
strain will be transferred onto that fold, others will fold down/stop
two types of strain accommodation in fold hinges
.
buckle folding of variable stratigraphic layer
increased viscosity ratio=higher wavelength
where does mineralisation occur in fold hinges
in dilational zones
