MIT researchers have identified a mechanism by which tiny, millimeter-wide wrinkles embedded within ancient rocks may have formed. (Learn more about the mechanism:http://bit.ly/1wIwMaQ)

In this controlled experiment, you can see the formation of ridges. Wave conditions were kept constant during the experiment, and the view is centered in the middle of the tank where orbital amplitudes are about 10 mm. Microbial mat fragments were added to the tank approximately half an hour into the experiment. Note that sediments do not move in the absence of mat fragments, and that ridges form in about 1 hour.
