Infrared satellite image showing mineral geology around China's Piqiang Fault. Decorrelation stretch processing of data has been used in this image to show subtle differences in the mineral composition of rocks and soil. Silurian sandstone is shown using shades of purple and blue. Devonian sandstone is also shown as blue threaded with purple, showing the similarities to Devonian sandstone. Image data obtained on the 24th of February 2005 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. | |
