Oncentration ofMinerals 2021, 11, x FOR PEER REVIEW3 ofMinerals 2021, 11,three ofin the Zefreh area [23]. Crustal stretching along these strike lip faults has facilitated the ascent and replacement of intrusive masses and also the formation of dikes plus the concentration of a number of mineralogical hydrothermal systems such as the Zefreh porphyry several mineralogical hydrothermal as well as the Kalchoye Zefreh porphyry copper deposits, copper deposits, Kahang, Zafarqand,systems such as theepithermal deposits, which are Kahang, these two and also the lineaments [23]. Volcanic activity within the Zefreh region ocrelated toZafarqand, tectonic Kalchoye epithermal deposits, that are associated to these two tectonic lineaments [23]. Volcanic activity inside the Zefreh area occurred within the eastern, curred in the Eocene to the Miocene. Pyroclastic and andesitic lavasfrom the Eocene towards the Miocene. and southwestern components lavas within the eastern, southeastern, in southwestern southeastern, Pyroclastic and andesiticof the location are the oldest rock unitsandthe region. components units location would be the oldest propylitic inside the area. These units have been altered These of thehave been altered to rock units because of magmatic activity. Within the central to portion, in theas a outcome ofdacites, phyllic and argillic central element, inside the Late Eocene dacites, propylitic Late Eocene magmatic activity. In the alterations zones are observed. Granodioriteand argillic alterations zones in the northeastern, penetrating dacite, pyroclastic, phyllic subvolcanics are presented are observed. Granodiorite subvolcanics are presented and andesitic lavas. Inpenetrating dacite,potassium alteration and abundant quartz-magin the northeastern, these stocks, weak pyroclastic, and andesitic lavas. In these stocks, netite potassium alteration and abundant quartz-magnetite veins are observed [24,25]. weak veins are observed [24,25].Figure 1.

Supplies and Procedures three.1. Data Qualities 3.1. Datathis study, ASTER Level 1 T (Precision Terrain Lupeol acetate Corrected Registered At-Sensor In Characteristics Within this study, ASTER The 1 T (Precision Terrain Corrected Registered At-Sensor Radiance) information were utilised.Level ASTER sensor is a multispectral imager on NASA’s Terra Radiance) information were employed. The ASTER sensor is usually a multispectral Altanserin Purity & Documentation imagernear infrared (VNIR) platform. ASTER has 14 bands in three subsystems, the visible and on NASA’s Terra (three bands), the shortwave infrared (SWIR) (six bands), plus the thermal infrared (TIR) (five bands), inside the array of 0.521.65 . The ASTER image includes a spatial resolution of 15 m inside the VNIR bands, 30 m inside the SWIR bands, and 90 m in the TIR bands [26]. ASTER satellite imagery was developed determined by geological requires, and it has been pretty efficient in thisMinerals 2021, 11,four offield over the last two decades [27]. ASTER data have an proper spectral and spatial resolution inside the SWIR range, where many alteration minerals is often distinguished [8,9]. ASTER SWIR detectors are no longer functioning on account of anomalously higher SWIR detector temperatures. ASTER SWIR information acquired due to the fact April 2008 usually are not usable and show saturation of values and serious striping. On the other hand, VNIR and TIR data continue to show exc.
