| Abstract: | In order to study the usage of remote sensing technology to identify tectonic mélanges, we took the Mazha tectonic mélange in the West Kunlun Orogen as an example. The marble in the mélange was analyzed for their spectral characteristics. The ETM+ image spectral inversion method was used to establish the linear relations between the measured spectrum and image spectrum. Assisted with enhanced transformation processing, the gray-scale distinction of different lithologies was expanded, the target information was highlighted and the image effect improved. Our work has also enhanced the utilization of measured spectrum and the accuracy of lithological information extraction. This method can be used to recognize the marble in Mazha tectonic mélange of the West Kunlun Orogen. |
