This 10.5 by 11 km sub-area in northern Chile was acquired by ASTER on
April 7, 2000. Dramatically displayed is a geological angular
unconformity: a contact between layers of rock at different angles. On the
right side of the image, Cretaceous sediments were tilted upward to an
angle of about 50 degrees, then eroded. On this surface volcanic
pyroclastic deposits were deposited as a flat sheet. The section of rocks
has been eroding from the east, exposing the tilted and flat rock layers.
The image is located at 24.8 degrees south latitude and 69.1 degrees west
longitude.
