Interpretation of Linear Structure from Remote Sensing Imagery in Huize Pb-Zn Deposit, Yunnan Province, China

Huize Pb-Zn deposit is located in the transfer part of Tethys Himalayan tectonic domain and the Pacific tectonic domain. This research used Landsat7 ETM+ remote sensing image with 30m spatial resolution. Based on the true color composite image with Band 321, we get the linear structure interpretation figure supplemented by spatial filtering processing. From the distribution regulation in radar chart of lineaments orientation and contour map of the density for the linear structure, we can see that the dominant structure orientation are NE and NW. They are consistent with basic structural pattern of Huize Pb-Zn deposit from a quantitative point of view. This indicates that a linear structure interpreted results can objectively reflect the regional tectonic features, so it is true and reliable.
