Determination of Hydrothermal Alteration Areas by Aster Satellite Images: Ağmaşat Plato- Zara (Sivas) / Turkey Sample

Abstract: Hidrotermal alterasyon alanlarının tespiti, maden arama faaliyetlerinin ilk aşamalarından bir tanesi olup özellikle porfiri tip zenginleşmelerin keşfinde önemli bir adımı oluşturmaktadır. Önceleri arazi çalışmaları ve gözlemlerle tespit edilebilen bu tür alanlar artık günümüzde gelişen teknoloji ile birlikte uydulardan elde edilen görüntüler üzerinde yapılan işlemlerle tespit edilebilmektedir. Bu çalışmada Sivas ilinin Zara ilçesinin kuzeyinde Ağmaşat Yaylası'nda belirlenen hidrotermal alterasyon alanlarının v… Show more

“…In recent years, remote sensing methods have been used widely in determining geological characteristics such as geological mapping, lineaments and hydrothermal alteration [1], [2], [3], [4], [5], [6], [7], [8], [9], [10]. This study was carried out as field and laboratory studies on the hydrothermal alterations which is located to the northern of Zara district of Sivas province.…”

“…Geological mapping is a process which is very difficult and requires a long time, high cost study on the field. Detection and classification of lithological units spread over large areas due to the development of remote sensing technology is important for geological mapping and detecting of hydrothermal alteration areas [1][2][3].…”

“…This study was aimed to test the usability of Matched Filtering (MF) which is one of the spectral classification method to identify the lithological characteristics of geological units and determining the contact between them by using the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image ASTER is one of remote sensors which is suitable in order to geological mapping [3,[9][10][11][12][13][14][15]. ASTER is a multispectral imaging sensor that measures electromagnetic radiation emitted and reflected from Earth's surface and atmosphere in 14 spectral bands which include: three visible and near infrared radiation (VNIR); six shortwave infrared radiation (SWIR) bands; and five recording thermal infrared radiation (TIR).…”
