Alteration Geochemistry of Volcanic Rocks around Sarcheshmeh Porphyry Copper Deposit, Rafsanjan, Kerman, Iran: Implications for Regional Exploration

Abstract: To discriminate the mineral potentiality of the trachybasalt around the Miocene Sarcheshmeh porphyry copper deposit, petrogeochemical characteristics of more than 45 samples of the volcanic rocks were studied. Sarcheshmeh is one of the world's largest Miocene porphyry copper deposits in a continental arc setting and contains about 1200 million tonnes of ores with an average grade of 1.2 percent copper, 0.03 percent molybdenum, 3.9 g/t Ag and 0.11 g/t Au. The biotized and sericitized trachybasalts around the Sa… Show more

“…The Sar-Cheshmeh porphyry copper deposit is considered the second largest global deposit of this metal, the most important in Iran, and has been exploited since ancient times. It contains roughly 1200 million tonnes of ore with an average grade of 1.2% copper, 0.03% molybdenum, 3.9 g/t Ag, and 0.11 g/t Au [48]. It is the first time that ML-based techniques (RF, SVM, GB, XGB, and deep-learning ANN) have been used for lithological mapping using ASTER remote-sensing data in the Sar-Cheshmeh copper mining region (Figure 1).…”

“…These granitoid rocks are cut by intramineral porphyry dikes composed of hornblende porphyry, feldspar porphyry, and biotite porphyry. The Sar-Cheshmeh copper deposit is placed in Eocene volcanic rocks, where a Miocene sub-volcanic granitoid unit intruded into andesitic host rocks [48]. Porphyry copper mineralization in this area is associated with well-developed zones of hydrothermal phyllic, argillic, propylitic, silicification, and jarositic alteration zones.…”

“…Within this belt, the Jebal–Barez area, which is part of the Kerman Cenozoic magmatic arc (KCMA), is known for its copper mineralization. Magmatic activity and copper mineralization within the CICMB are generally associated with porphyry copper mineralization, including deposits such as Sungun (Hezarkhani et al ., 1999), Sar Cheshmeh (Waterman & Hamilton, 1975; Shahabpour, 1982; Hezarkhani, 2006a; Aftabi & Atapour, 2011), Meiduk (Hassanzadeh, 1993; Boomeri et al ., 2009) and many other sub‐economic orebodies (Zarasvandi et al ., 2005; Hezarkhani, 2006b). Copper deposits in the KCMA of Iran are genetically related to Miocene porphyries.…”

“…Iron oxide/hydroxide minerals (hematite, limonite and goethite) that have diagnostic absorptions within the visible near‐infrared region and hydroxyl (OH) bearing minerals (clays, carbonates and sulphates) that contain absorption features in the shortwave infrared portion are very important in remote‐sensing studies. Anomalous percentages of potassium content in the sericite zone are often observed around porphyry Cu mineralization areas, reported in many case studies (Dickson et al ., 1996; Ulrich, 2002; Aftabi and Atapour, 2010; Wu et al ., 2019; Melfos et al ., 2020). A possible scenario to correctly plot these alterations is simultaneous consideration of the ASTER satellite imagery data and the airborne radiometric geophysics.…”
