Patterns of Scheelite Mineralization in the Muruntau Gold Deposit, Uzbekistan

Origin of ore fluids in the Muruntau gold system: Constraints from noble gas, carbon isotope and halogen data

“…Arifulov, 1976;Uspenskiy and Aleshin, 1993;Kempe et al, 2002), whereas the medium-temperature stages are characterized by albite-, carbonate-apatite-, chlorite-and sericite-dominated alteration assemblages (e.g., several authors in Shayakubov et al, 1998;Kempe et al, 2002).…”

“…An additional quartz sample is from a poorly recrystallized stockwork veinlet from the central part of the Muruntau mine. The brownish, deformed scheelite, which is associated with Au 1 mineralization in time and space [scheelite 2 of Uspenskiy and Aleshin (1993) and Kempe et al (2001a)], is derived from a main quartz vein at Myutenbai (+78 m), which is similar in appearance to the Muruntau central veins.…”

Gold Deposits in China: Main Types and Potential

“…The Muruntau orebodies are hosted by the Ordovician-Lower Silurian Besapan Formation, which consists mainly of siltstone and sandstone with varied amounts of carbonaceous materials, carbonates, and intermediatefelsic volcanic component, and is metamorphosed into greenschist facies. Gold is associated with W in the Muruntau deposit (Uspenskiy and Aleshin, 1993), and with Ag, Pb, Sb, and Bi in some other deposits of the area (Berger et al, 1994). Gold mineralization is presumed to be genetically related to granitoid intrusions that were emplaced along a shear zone of the Muruntau gold field during later Carboniferous and Permian time (e.g., Kudrin et al, 1990;Kotov and Poritskaya, 1992;Marakushev and Khokhov, 1992;Zairi and Kurbanov, 1992).…”
