Kinematic information is not available, but the younger-on-older geometry and linkage to the Bessel Fjord and Kildedal shear zones suggest extensional displacement as well. (2) The second segment is a high strain zone bounding the west side of the Eleonore Bay Supergroup that shows evidence for top-to-the-east extensional shear (Friderichsen.

f 1 Z and f 2. Kinematic models determine the evolution of a geometrical structural model (e.g. Laubscher, ), so that the paths of material points in the model can be followed and examined. Kinematic indicators, i.e. information about the kinematic vectors involved in the structural development, are, for instance, slickensides on faults, axes of folds.

Abstract. Thrust faults in inverted extensional basins may not exhibit the simple low-angle, ramp-flat thrust trajectories that are characteristic of many foreland fold and thrust belts, but are expected to show more complex geometries controlled by the architecture of the earlier extensional fault system.
Model results illustrate how shortening velocity has an important influence on the geometry and kinematics of the resulting wedge. In general, for models having similar bulk shortening, the accretionary wedges with higher velocities of shortening are roughly steeper, higher and longer, as well as having larger critical wedge angles and height.
The development of the analogue model thrust fault-related folds by progressive changes in kinematics, from décollement folding to thrust-tip folding and finally thrust-ramp folding, compares. Kinematic studies of small-scale extensional faults show a NNE to NE maximum stretching direction (λ1), suggesting that the Atuel depocenter acted as an oblique rift.

Calculate the heave and throw of faults, individually and cumulatively. A distinct spatial relationship between surface faulting, magmatic intrusions and volcanic activity exists in the Aegean continental crust. In this paper, we provide detailed structural observations from key onshore areas, as well as compilations of lineament maps and earthquake locations with focal plane solutions from offshore areas to support such a relationship.

About The Book. This up-to-date introduction to kinematic analysis ensures relevance by using actual machines and mechanisms throughout. MACHINES & MECHANISMS, 4/e provides the techniques necessary to study the motion of machines while emphasizing the application of kinematic theories to real-world -of-the-art techniques and tools are utilized, and analytical techniques are.
Its geometry is related with the inverted extensional system. In particular, the three-dimensional geometry, including the saddles between culminations, is inherited from the previous transfer faults of the segmented rift margin.
Available seismic data and 3 exploratory wells constrain the geometry. Here we present a two-dimensional kinematic model of linked basement faulting and extensional fault-propagation folding which builds upon an earlier adaptation of trishear (Hardy and Ford, ), and use this model to investigate the influence of shear zone geometry and the rate of fault propagation on both the geometry of, and the strain.

McClay, K.R., b, 2-D and 3-D analogue modelling of extensional fault. Any model of rockslide-avalanche kinematics or dynamics must take such structures into account, and the analogue models provide a useful way of exploring their development and significance.
The models reproduce all structural features seen in natural examples, and the runout in the experiments is similar to that of natural small-volume events.The three-dimensional geometry and kinematics of brittle structures within the immediate hanging-wall of construct a three-dimensional model of a large extensional fault with a distinct hanging-wall rollover (figure 7).
This model was restored and a strain analysis performed to show the distribution of principal strain across the fault.Instead of this extensional setting being dominated by normal-faults, a strike-slip regime is ubiquitous across the island.
Furthermore, these strike-slip faults are parallel to rift-related structures such as dikes and fissures. This style of faulting is not predicted by traditional views of seafloor spreading and extensional tectonics.
