Çalışma bölgesi, Landsat 7 ETM verileri kullanılarak çeşitli uzaktan algılama teknikleri ile incelenmiştir. Crosta tekniği, görüntü zenginleştirme tekniklerinin önemlilerinden biridir ve özellikle demirce zengin ve hidrotermal alterasyon zonları gösteren madenlerde, cevherleşme alanlarını belirlemede son yıllarda sıkça kullanılmaktadır. Çalışma alanında, hidrotermal alterasyona uğramış ve demiroksit’ce zenginleşmiş bölgeler (Alakeçi-Kısacık) özellikle seçilmiş ve Crosta tekniği, seçilmiş 6 band ve 4 band kullanılarak ayrı ayrı denetlenmiştir. Çalışma sonunda, elde edilen verileri göz önüne alındığında, klasik metodlar kullanılarak daha önce belirlenmiş cevherleşme bölgelerinin, kullanılan Crosta tekniği ile de başarı ile belirlendiği görülmüştür.

Crosta Technique Applicatıon On Bayramic (Alakeçı-Kısacık) Mineralized Area By Using Landsat 7 Etm+ Data

Öz

The study area investigated by using Landsat ETM data and various image inhancement techniques was applied. Crosta technique is one of the important image inhancement techniques and commonly used in determining hydrothermal areas and as well as ironoxide enriched areas. In this study, especially hydrothermally and ironoxide enriched areas( Alakeçi-Kısacık) were chosen intentionally and Crosta technique was applied and checked by using selected 6 ETM bands and 4 ETM band sets separately. At the end of the study, the determined hydrothermally and ironoxide enriched areas were seen well-adjusted the pre-determined mineralized areas which were found by using all classical geological and geochemical techniques.
