This NASA Earth Observatory image released January 16, 2014 the Operational Land Imager (OLI) on the Landsat 8 satellite shows a view of the Keping Shan thrust belt as it appeared July 30, 2013. The ridges are oriented northeast to southwest and stretch from Kashgar to Aksu, China. Narrow basins separate the ridges, and shallow lakes are visible at some of the lowest points. Lighter-colored areas are sediments left behind by dried-up lakes. While most of the region is arid and barren, a green strip of vegetation traces the Kashgar River in the lower part of the lower image. The foothills of the Tien Shan mountains are visible near the top of the image.This part of Xinjiang province has a rich and varied geologic history. About 300 million years ago, the Tien Shan mountains began forming when the Tarim Block—a mass of land that was once part of Australia—collided with Eurasia. During the Mesozoic Era (252 to 66 million years ago), a series of island arcs (curved chains of volcanic islands) continued to smash into Eurasia, further building the mountain range. About 80 million years ago, the Indian subcontinent started colliding as well, triggering a whole new phase of mountain building.
