Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 653 Detecting and mapping of different volcanic stages and other geomorphic features by Landsat images in ‘Katakekaumene’, Western Turkey F.Sancar Ozaner MTA Jeologi Etüd/eri D aire si, Ankara, Turkey ABSTRACT: Kula and its surroundings which is located in Western Turkey has been chosen for the study. Some geological and geomorp- hological units which were differentiated by this study have already been mapped by different researchers. The aim of the study is to prove that, some of the units which were mapped by long and expensive field works already, could also differantiated on the Landsat images. The boundries of three eruption stages of basaltic rocks on the southern part, and andesitic rocks on the northern part were mapped. Shifting of the eruption sites from north to south, and, changing of the volcanics from andesitic type to basaltic,have been detected on the Landsat images. Thus, new targets related to further earthquake studies become evident. 1. INTRODUCTION The study area have already been worked by numbers of research es. A well known historian, Strabon, visited the area before birth of Christ and named Kula basalts as "Katakekaumane". Later on, (Philippson 1913), (Canet and Jaoul 1946), (Beekman 1964), (Bergo 1964), (Erin? 1970), (§enol and Karabiyikoglu 1977),(Ercan et al 1977,1980), (Bircan et al 1982), (Ozaner 1984), worked and mapp ed the area. Some of these researches focused their attention espe cially on mapping of Kula basalts, while the others also mapped sedimentological, geological and geomorphological features of the area. The auther first used Landsat images of the area, involving with the project, (Bircan et al 1982), and realized that most of the features which had already been mapped are also detectible,— in some cases more accurately mappeble— on Landsat imagery. In Addition, synoptic view advantage of Landsat images has created fruitful conclusions for the tectonics of the area which are not contradict to global plate tectonic results of Western Turkey. The author helped and partly quided to the study of Hakim (1983) at this part of the country. 2. INTERPRETATION Landsat image interpretation has been made on the image which was recorded on 16 September 1975. 1: 500.000 scale of Band 5, Band 7, and colour composite image, and 1: 35.000 scale aerial photographs of the area were used during interpretation. Colour compasite image was not printed for abstaining from extra expens es of publication. As above mentioned, volcanic terrain units are the most striking features of the images. For this reason, interpretation will start with these units. In the north of the imagery, two giant andesitic- riolitic heaps, namely Asi Tepe and Yagci Dag, are very distinct forms by its circular shape, relief impression and radial drainage patterns. Due to fact that andesitic lavas are less fluid than basalt ic lavas, it gives a mass morphology. The visual impressions of the ruggedness was formed by differences of illumunation of the slopes which were transformed into different grey tones. There is not an absolute age for this rocks. However it is estimated to be of Early Upper Miocene (Ercan et al. 1977). Approximately, at the centre of Landsat image (in other words: southern part of andesitic heaps), a well known "Katakekaumane" is located. Here, three main basaltic eruption phases could be mapped by typical image characteristics, such as grey tone differ ences, site and shape. The first stage basaltic lavas take place at the southern part of older basalts. This intermediate lavas do not show circular shape, because they have not been severely dissected yet.Thus, they don't show morphological impression. However, they do show a distinct dark grey tone which starts at close to watersheds and are bounded with Gediz River. In Band 7, and in coloured composite image, this site effect assisted to the interpreter for coming the conclusion that they had been formed by flows of fluid lavas. The boundries of this stage are seen clearly in Band 7 and in colour composite image. In Band 5, very dark grey tone at point A, reflects vegeteta- tion on limestones and confuses the boundry. Vegetation appears red in color compasite image and clears the problem. In aerial photos, under steoroscopic view, these two volcanic phases are easily discriminated by their different altitudes, which represent total erosion between two eruption times. Most of craters and co nes of this stage can be recognised on Landsat imagery. This lava is estimated to be of Late Upper Miocene (Ercan et al, 1985). First and second lavas appears with naphta colour in colour compo site image. Recent basaltic flows appear with three distinct black patches in Landsat images. In Band 7 and 5 and in colour composite image there is not any difference between lake of dam and third stage of lavas, from the point of colour. Site effect which has the same
