Two-dimensional kinematic and flexural basin modeling

Main features:

  • Basin subsidence and rift flank uplift/thrust-generated topography are calculated as a function of time.

  • The two-dimensional extensional or compressional kinematic displacements across one or multiple faults (listric or planar) is specified in the kinematic model.

  • Crustal extension/shortening in the hangingwall/footwall blocks can be incorporated.

  • Inclusion of depth-dependent extension/compression partitioning due to the effect of intracrustal detachments.

  • Inclusion of inversion events using the kinematics of crustal and lithospheric mantle extension/shortening within the hangingwall and footwall blocks.

  • Basin fill with compacting sediments is included. The compaction characteristics are spatially variable.

  • Erosion of emergent and submarine topography (producing peneplains and deep-sea unconformities).

  • Eustatic curves can be included (e.g., the long-term eustatic fall since the late Cretaceous).

  • Flexural isostasy is employed throughout the calculations, during both the syn-tectonic and post-tectonic development. The effective elastic thickness of the lithosphere is determined as the depth to a particular isotherm (nominally 450o C) or a user-defined constant. In general, the effective elastic thickness is a function of space and time.

  • Profiles of the time-line stratigraphy and basin architecture at any time during its evolution (i.e. both during and after the tectonic event).

  • Important parameters such as the gravity effect and heat flow can be predicted as functions of space and time.
