■wiw characteristic as outlined for the second stage, assisted interpreter for discriminating these lava flows from the dam lake. Whitish areas in the northern part of lake which indicate the presence of accu mulations of very recent sediments is another criteria for discrimi nations. Most of the craters of the youngest stage are visible in Landsat images. According to radiometric data, this lava is about 25.000 years old (Ercan et al 1985). Mapping of the volcanic rocks on Landsat imagery shows approxi mately the same accuracy as from 1: 35.000 scale aerial photog raphs of the area. Metamorphic rocks appears with distinctive morphological impress- sion which is determined by watersheds and drainage patterns. Ru ggedness of the unit is much apperant in Band 7. Soft Neogene formations are mostly seen in whitish tones and could be mapped by the help of Band 5, and colour composite image. White tones represent bare slopes consisting of sandy silty, tuffaous materials which reflect much of the electromagnetic energy in dry season. Limestone plateaus which have been formed in Neogene basin rocks are also distinct terrain features, occur in the north of first stage basalts. They are easily detectable units with flat topography, faint signs of internal drainage and site characteristics. These terrain features have been isolated by scarp zone which is transferred to badlands. Badlands occur in the areas where soft Neogene deposits are capped by limestone or basalt plateous. They appears as stronly dis sected fine textural drainage network in Landsat imagery. Narrow straight ravines cause the relief impression. Badland boundries were not mapped but typical areas were indicated. The boundry between Neogene soft formations and Quaternary deposits of Gediz Graben is very clear in Band 5, and especially in colour composite image. Graben buttom appears in darker tones in Band 5 and bright red in colour composite, which reflects parcels of various crops and orchards and makes a distinct contrast with the white Neogene sediments. Capital letter M in Band 7, points faint meandering belts of Gediz River. 2.1 Analysis of lineaments The following linear features have been analysed on the Landsat image: Certain faults; distinct on Landsat imagery and proved by earlier researches in the field. Possible faults; clear on Landsat imagery as distinct lineaments and have been decided possible faults in the field. Faults; derived from the rows of craters and cones which are vi sible in Landsat. Most of the faults can be seen on Landsat images clearly. In add ition, synoptic view advantage of Landsat imagery has created fruitful conclusions for the tectonics of the area. It can easily be recognized that the oldest andesitic eruptions occured in the north ern part, while relatively younger three basaltic eruptions took place in the middle and southern part of Landsat image. Even these three basaltic stages have been arranged in rows which are conti nuously shift towards south. According to the rows of cones, the first stage basaltic lavas have been erupted from roughly E—W trending faults or cracks. The mam ... *. ■ - / f a . , ,1 - , i M' ’«*,*■* ■ , *• >* VH- i* 1 .

Landsat Band 7 rows of the second stage craters which are situated south of first stage, imply that they came to the surface by WNW—ESE and SW—NE trending faults an cracks. The youngest lavas also erupted by the same trending weak zones as happened in the second stage, but shifts south, relative to second stage. At the upper most south of image,a young depression can be seen. This NW— SE trending graben is recent active formation of south shifting tectonic activity. In the light of such tectonic pattern, one can understand that further tectonic studies and earthquake re searches have to be targeted at the southern part of the area. 654 Graben Buttom Figure 4.
