    Mark, Thanks for the detailed commentary. Now we know some features to look for.

    These photos have enabled us to compile additional evidence to identify the deformation mechanisms and kinematics of the system. Most structural geologists like to examine the micro-structures using a petrographic microscope, and to this day it is still the best way of identifying strain. However, the images above taken by the macropod has provided a stronger argument to our hypothesis (that the shear zone is brittle and ultra cataclasistic). From the photo on the right (TT10.2.10.01), looking perpendicular to slicken lines , we found the thick black line to be glass, pseudotachylyte, meaning that it is a plane from when an earthquake occured, It also means that the shear zone is cataclasistic. We can determine from the image that this fault rock is late stage and recent because the ultracataclastic line has been disjointed. The offset zones are Reidel shears from another earthquake that occured more recently (seen in an image not yet posted). The pseudotachylyte taken from another billet sitting 6 mm away from the billet above, has not been disjointed and is completely straight with horse-tail feathering, meaning that the shear zone is not only late-stage but it is continuously an active thrust zone, which is odd because the fault in which this specimen was taken from has a dip angle of ~70 degrees. It is extremely steep. For more information, please go to gsa.confex.com/gsa/2011NE/finalpro gram/abstract_185353.htm Will open in

    You're welcome Mark. When you get the time add some comments on features so we can get an idea for lighting and magnification that would make these images most useful to the users.

    WOW Thank you so much Tony, these images are fantastic, did you notice that even the first set you uploaded at .08 Gigapixels already has an explore score better than the Phoenix Mars Lander Gigapan Image? I was talking to Dr. Lewis today and he mentioned that researchers in paleontology would love to get there hands on the macropod.
