| Abstract: | The digital processing of the TM image of Laguigangri area, such as K-L transform, K-T transform, and ratio operation has confirmed in the result images, the typical three-layer configuration of Laguigangri metamorphic core complex zone. Moreover, the analysis and contrast of a series of result images have enabled the authors to have summarized the image characteristics of the core, the contact belt and the cover of Laguigangri metamorphic core complex zone. At last, they have put forward the changing law among the Laguigangri metamorphic core complex zone. |
