Texture feature of remote sensing image for the recognition of hydrothermal uranium ore-field in south China

摘要

Hydrothermal uranium deposit is very important in China and mainly distributes in the south of the country. The deposit often occurred in an area of multi periods magmatism and tectonic action. In order to summarize the characteristics of this area in remote sensing, method of visual interpretation, calculation of fractal box dimension and a-f(a) multi-fractal spectral are used to study the texture feature of ETM image in 11uranium ore-field and their neighbor area.
