Movie
1661-01. Movie illustrating the progressive development of convergent
strike-slip fault zones in plan view (experiment 1661). The first
frame shows the location of computerized tomography (CT) acquisition
planes. Rectangle in last frame indicates area of 3D analysis by X-ray
CT (27 x 23.8 cm; see Movies 1661-03, 1661-04, 1661-05 and 1661-06).
Initial grid spacing is 5 cm. Time between frames is about 10 minutes.

1661-02. Movie of cross-sectional evolution of experiment 1661. Location
of CT sections A-D is given in the first frame of Movie 1661-01. Note
that the position of the model changed with respect to the fixed CT
image acquisition planes during progressive deformation. Initial width
of model is 26 cm; initial height is 3.5 cm. Time between frames is
8 minutes. (Select

Movie
1661-04. Movie showing serial horizontal sections through convergent
strike-slip fault zones. Major fault zones strike at about 15°
to the longitudinal sidewalls. Horizontal sections were computed from
3D data set. First frame is near the base of the brittle layers. Vertical
distance between frames is 0.5 mm. Computer animation shows 66 frames
at three frames per second. (Select

Movie
1764-04. Movie showing serial horizontal sections through final deformation
stage. These sections show the complex fault pattern at depth in great
detail. Note the oblique thrust faults (and associated vertical relief)
between major convergent strike-slip fault zones in upper part of
movie. First frame is near the base of the brittle layers. Vertical
distance between frames is 0.5 mm. Computer animation consists of
64 frames. (Select

Movie
1820-02. Movie of cross-sectional evolution of experiment 1820. Pop-up
structures form initially. Steep strike-slip faults form at later
stages and occur either confined within pop-up structures or between
different pop-up structures. Location of CT sections A-E is given
in the first frame of Movie 1820-01. Initial width and height of model
is 26 and 3.5 cm, respectively. Time between frames is 10 minutes.

Movie
1820-03. Movie illustrating the fault geometry by a series of serial
vertical sections. Fault dip changes along strike in the right-hand
side of the images. Note also how subvertical strike-slip faults change
their dip direction along strike and merge at depth with bounding
thrust faults. Each of the 135 frames represents a 2mm thick cross-sectional
CT slice. (Select
