The package Fabric8
for Windows consists of 30 strong computer
programs for the solution of various problems
in structural geology, petrofabrics, neotectonics,
rock mechanics, engeneering geology, physical geography,
geophysics, and other fields of earth sciences. The
programs have been in use for a long time.
Statistical
parameters of both three or two
dimensionally distributed orientation data
(lineation, schistosity, bedding, joints, fold axes,
universal stage data) can be calculated and graphically
presented in stereonets.
Submaxima
in the distribution of orientation data are found
and tested for significance.
Displacement
data (slickensides and striations) are used to calculate
and plot the orientation and shape of paleostresses.
Other programs
enable the reconstruction of a data file from a bitmap
of a stereonet by clicking on the points.
Several
programs analyse fold shapes with Fourier coefficients
or with isogon methods.
Strain
anlysis can be done with outcrop data (Talbot method) or with
images of the distribution of strain markers (Fry method, Panozzo
method).
Structural
maps can be plotted from structural data and
their coordinates.
The entire
package was developed by Eckart Wallbrecher.
The package contains
programs for the following operations:
