It is difficult to identify the relative ages of lithological units only relying on remote sensing images with few reference data. In case of lack of geological references and difficult fieldwork, it is limited to use remote sensing images for interpretation. To solve these problems, the authors firstly introduced the theory of structural hierarchy to geological interpretation and presented a new method to classify the regional structures and small-scale structures extracted from OLI and GF-2 data respectively. To some extent, this method can determine the relative ages of the lithological units, the events of tectonic evolution and the advantageous areas for metallogenesis in the areas with only a few geological reference data. And it provides a new way for exploiting the advantages of high ground resolution of GF-2 so as to promote the development of remote sensing geology in foreign areas.
