Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Analysis of lineaments and major fractures in Xichang-Dukou area, Sichuan province as interpreted from Landsat images Lu Defu, Zhang Wenhua & Liu Bingguang Institute of Geology, Academia Sínica, Beijing, China Xu Ruisong & Jang Baolin Institute of Geologic Technology, Academia Sínica, Guangzhou, China ABSTRACT; The Xichang-Dukou area in Sichuan province of China was studied using Landsat imagery and exist ing geological maps. A number of major and minor lineaments were identified which have been accounted for in available geologi cal maps. N-S and ENE fault and lineament systems are present in the area. Rose diagrams were analyzed to assess direction and frequency of lineaments. The fault zones are divided into two types: linear and arcuate. INFORMATION AND METHOD The area studied is located at the southern part of Sichuan province in China. Three Landsat images, scale 1 :500,000, cover about 60,000 ki? from north Minning-Yuexi in Sichuan province to south Yongren in Yinnan province. Geological maps of different type and scale are also available. Conventional visual interpretation methods were used, including modus of density slicing and local enhancement of lineaments for part of the area. ANALYSIS OF LINEAMENTS It is generally believed that fault zones and weak crustal zones are represented by lineaments on space imagery. The lineaments on Landsat were interpreted by considering those lineaments which could be clearly determined as fault zone, fractured structure, linear river valley, linear tonal anomely zone etc,» The lineaments larger than 5k™ length were only drawn on this map scale. On the basis of the directional distribution of the lineaments 4 groups have been distinguished, mainly in NS,NNW,EW,ENE direction, in which the NS (345°-5 ) and ENE(65°-75°) trends are the strongest and the most distinct on the imagery. The linea ments in NS direction are principally present in the Anninghe valley and towards the west. They are characterised by their continuity and greater leng th. The EW lineaments occur in two areas: one from Dukou to Huapin and another one from Xichang to Muli. Their length is less than that of the NS lineaments.(Figure 1) All linear features derived from the Landsat imagery and from existing geological maps were plotted in rose diagrams, as shown in Figure 2 and 3 respeclively. The rose diagrams for length and frequency dis tribution are compiled in 5 interval classes.Fig.2 indicates that the lineaments longer than 5 km in length account for the dominant NNW, NS and ENE trend. Fig.3 shows a preferred orientation of the near NS and ENE major faults. A difference was found in preferred orientations between the linea ments as interpreted from the Landsat imagery and geological maps. The lineaments show two length distributions in the direction 345 and £5 on the Landsat imagery and in the direction Q 355 0 and 5 on the geological map. Directions 20 - 30 clearly present on the geological map are less exhibited on the Landsat»
