Abstract: The ZY-3 satellite images and LandSat-8 multispectral data are applied respectively in the remote sensing interpretation of 4 sheets of 1: 50 000 regional survey projects including Niufentai Forest Farm in Inner Mongolia. Through comparative analysis of the above two sources of data, it is found that the former is suitable for interpretation of terrain and landform, while the latter plays a greater role in interpretation of linear and ring structures, with which 29 NE- and NW-oriented linear structures and 29 minor ring structures related to volcanic eruption are interpreted, as well as the boundaries of Quaternary, Neogene Wuchagou Formation, Paleozoic, Upper Jurassic-Lower Cretaceous strata and rock mass. Faults are found in 11 linear structures, and volcanic edifices are delineated in 11 ring images through field verification. It is proved that the interpreted boundaries of Wuchagou Formation and Quaternary are roughly consistent with the boundaries by field survey. The interpreted Paleozoic boundaries almost coincide with the verified boundary of Early Paleozoic Hellestein tectonic melange. The rock mass is confirmed to be Early Cretaceous syenogranite.
