This (picture and sculpture) does not do justice to his work (in my humble opinion).
Check out "rivers and tides", a movie of his work.
Sarclet thrust fault where the buckled sediments on the top layers were thrusted from an east to west direction. Photographed on 12 April 2009
On my second visit to Lake Cowal back in early December, I was told about a place that was of great interest to geologists visiting the nearby gold mine. This trip I headed out to have a look.
Following is the information I was given to explain what I was going to see.
"The outcrop is part of the Booberoi Fault and features sheared Late Silurian-Early Devonian Edols Conglomerate (Sherwin, 1996) showing stretched quartzite and vein-quartz pebbles in a quartz white mica-chlorite matrix, which was probably a muddy sandstone. Mesoscopic kinematic indicators show at least two movement episodes: a horizontal sinstral movement and a near vertical reverse (west side up) movement. The movement direction can be discerned from the asymmetry of the matrix surrounding the pebbles and the mineral elongation within the matrix."

The road ran straight down an ancient fault line, which is also the entrance to Arches National Park.
Oh boy. Today's quake and tonight's aftershock were both on the Hayward Fault. 4.0 and 3.8. both felt really f-ing strong.

Above the Coire Uaigneich granophyre and Middle Jurassic sediments the hornfelsed basalts are seen to be faulted due to intrusion of Coire Uaigneich Granophyre. Uplift probably induced listric normal faults in the basalts similar to Ardnamurchan uplift and consequent mass wasting processes.
The Niguelas fault plane, south of Granada.
Poorly sorted calcareous clastic rocks have been polished by fault movement - very slick slicken sides! The kids were enjoying adding to the polish by sliding down it!
at right is the American Plate, left the Pacific Plate. the fence is displaced by 7-10 ft during the 1906 San Francisco Quake
