Abstract

Remote Sensing is a useful technique for analysis of the fractures through which magmas rise in the crust and subsequently cause volcanism or mineralization. These fractures appear as lineaments on the ground surface. In order to detect the lineaments in Kyushu Island, 'slope-shaded' maps were drawn based on Landsat images and topographic maps treated by computer, in which slopes facing a certain direction were shaded to emphasize the elevation. Since this topographic maps were drawn using an imaginary light source shining from specified directions (N, NE, NW and W), it was possible to detect even those lineaments which would otherwise be difficult to be found from the Landsat images only. The lineaments detected in Kyushu Island are divided into four orientation groups; N -- S, NW -- SE, NE -- SW, and E -- W, respectively. In particular the E -- W lineament pattern can be mechanically obtained by putting the slope-shaded map from the Landsat images upon its negative map and then slightly shifting one of them. This lineament pattern reflects an E -- W stress field in Kyushu Island.
