2. T-TECTO is a computer program which
enables fast and simple paleostress and
kinematic analysis of heterogeneous and
homogeneous fault-slip data using the Gauss
method (Žalohar and Vrabec, 2007).
The program is based on the classical
philosophy of fault-slip data inversion which
involves the concept of the best-fitting stress
tensor.
3. In the Tools/Beds, joints (fractures), lineations an fault-sets the
following fuctions are now available:
Fault-sets analysis (parallel-faults interaction),
Intersection analysis (the wedge faulting or intersecting-faults
interaction),
Fault-sets and intersection analysis (Parallel-wedges interaction).
4. Determination of the maximum and minimum horizontal stresses.
Determination of the maximum horizontal shortening and extension.
Analysis of the relative vertical deformations.
Automatic optimization of the VGF parameters.
Visualization of the Multiple-slip mechanisms (MSM).
Visualization of the P and T quadrants and fields.
Cosserat extension of the MSM weighting factors determination.
Analysis of the reliability of the Cosserat relative microrotation parameter W (C).
Increased maximum number of faults (now with 2000 faults limitation)
5. T-TECTO 3.0 – the newest version of T-TECTO
In september 2009, the T-TECTO 3.0 has been released. Numerous new
functions allow a more detailed analysis of fault-slip data, earthquake focal-
mechanisms, various fractures, extension veins, disjunctive foliations and other
structures that form under high stress. T-TECTO 3.0 also allows a detailed
analysis of the reliability of the solutions. The new functions include:
•Determination of the maximum and minimum horizontal stresses.
•Determination of the maximum horizontal shortening and extension.
•Analysis of the relative vertical deformations.
•Automatic optimization of the VGF parameters.
•Visualization of the Multiple-slip mechanisms (MSM).
•Visualization of the P and T quadrants and fields.
•Cosserat extension of the MSM weighting factors determination.
•Analysis of the reliability of the Cosserat relative microrotation parameter W (C).
•Increased maximum number of faults (now with 2000 faults limitation)
