The paper selected sandstones in Kharrazi region of Kalpintag Formation as the research object, using the open source image processing software of ImageJ to measure the grain size of the slice image, and then Matlab software was used in statistical analysis of the data. Characters of granularity parameters and accumulative probability curve shows that Kharrazi region of Kalpintag Formation is of neritic facies. Source

The information of tectonic structure and surrounding rock alteration is extracted from ETM remote sensing data through data amalgamation and image enhancement by ratio transformation, main component analysis and digital elevation model (DEM). According to the image characteristics of linear structures, three structural trends are identified: nearly EW, NE and NW direction. The paper uses fractal theory for remote sensing alteration anomaly extraction, and contrast the result with fault and geochemical abnormal area. Source
