Pages

Abstract

 Summary: In this study, satellite images, and Aeromagnetic data were analyzed to investigate the Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal potential in the Ardebil-Sabalan area in Ardebil province. Thermal activity monitoring in and around active volcanic areas using remote sensing is an essential part of volcanology nowadays. In this study, a Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal survey is conducted in sabalan area of Ardebil province in NW IRAN using TIR data from Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and ASTER (AST L1B) sensor. Magmatism contributes abundant Thermal source to study area and the faults provide Thermal channels for heat transfer from interior earth to land surface and facilitate the present of Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal anomalies. The magnetic investigations showed that a deep magnetic anomaly exists in the southern part of the area. These magnetic anomalies were correlated with Thermal anomalies Introduction: Lu et al. (2008) used Landsat ETM++ Thermal image to detect Thermal anomalies strongly correlated with faults in certain scales in the Jiangshan-Shaoxing fault in the Zhejiang Province of China. They defined Thermal anomalies as areas with temperatures higher than the spatial background. In a Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal resource exploration in Akita and Iwate prefectures, northern Japan, Noorollahi et al. (2007) showed that 95% of the production wells are located in a zone within 6000m to the active faults and 4000m of hot springs in Japan. Thermal infrared remote (TIR) sensing is an efficient technique to obtain the land surface temperature (LST). With ever increasing attempts on looking for alternative energy sources, TIR remote sensing has become a popular technique in the exploration of Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal resources. The first application of TIR remote sensing in Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal exploration can be dated back to the middle of 20th century. The central cone, Nakadake, is the most active volcano in Japan, where repeated historic magmatic eruption occurred (Terada and Sudo, 2012). The eruption processes involved strombolian activity, phreatomagmatic explosions and ash emission (Ono et al., 1995; Miyabuchi, 2009). The Nakadake crater erupted characteristically black ash during the active eruption period (Ono et al., 1995). The aim of this study is to analyze remote sensing and magnetic data for evaluating the Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal potential zones in an area located in the eASTERn of Ardebil Province. Methodology and Approaches: The data studied in this research includes ASTER – ASTL1 B (day and night) reflectance and LST products, for the year 2009, Landsat ETM++ day-time image on 2015, Aeromagnetic data collected by Houston Texas Co., America, in 1974-1977. A comparison of the day-time and night-time images can reveal the surface Thermal differences for detecting Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal anomalies. Hellman and Ramsey (2004) investigated the Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal hot springs of Yellowstone National Park using the Thermal infrared data of Thermal Emission and Reflection Radiometer (ASTER) and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS). Vaughan et al. (2005) and Coolbaugh et al. (2007) studied the Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal hot springs in Nevada of the United States with TIR remote sensing. Fred et al. (2008) provided a first quantitative representation ofthe surfacial Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal activities in Yellowstone National Park using the ETM+ Thermal infrared data. New-generation, advanced remote sensing has been used in the past few decades in environmental geology, mineral and hydrocarbon exploration. The first Landsat satellite, launched in 1972 within the Landsat Data Continuity Mission, will have a nearly42-year global record. Apparent Thermal inertia of the three sensors was calculated using albedo and LST difference of day and night (Sabol et al., 2006; Scheidt et al., 2010; Chang et al., 2012; Qin et al., 2013). After removal of the noise from observed magnetic data, processing steps were considered, including IGRF subtraction for the proper years, reduction to pole, and upward continuation. The magnetic data was finally interpreted to locate the hidden intrusive bodies and faults. Results and Conclusions: The results of this work also suggest that TIR remote sensing is an important technique for Thermal/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">GeoThermal exploration with its high efficiency, simplicity and accuracy in temperature retrieval. Three Thermal anomalies were detected on the maps and charts obtained for the average temperature difference and apparent Thermal inertia. One anomaly is located in the Sabalan area and the other one is situated in the Northern part of the Ardebil side. The results of magnetic interpretations confirmed Thermal anomalies showing a deep magnetic anomaly in the southern region and another magnetic anomaly in the hot spring.
