摘要
Using the data from the USGS (United State Geological Survey), JPL (Jet Propulsion Laboratory) and JHU (Johns Hopkins University) spectral databases, this paper studies the quantitative relation between SiO2 content and thermal emissivity specra of 52 samples of igneous rocks, and two multi variables stepwise linear regression equations are modeled based on this relation. The ASTER thermal infrared data are used for inversion and retrieval of the SiO2 content in the east Dong-Wuzhumuqin area, South of Great Hinggan Mountains. The result of inversion conforms to the geological diagram and field investigation.
