Muruntau gold deposit
The Muruntau gold deposit is situated in the
The giant Muruntau Gold deposit was discovered in 1958. The area was a source of
Tectonic setting
The Kyzyl Kum area is underlain by three main tectonic units.
Tectonics
Caledonian (Silurian) deformation
The Kyzyl Kum area basement is strongly folded and
Late Carboniferous deformation
There is evidence of a deformation event during the
Permo-Triassic deformation
A major Permo-Triassic deformation event in the Karatau Range occurs north of Muruntau as well.[3] This event is synchronous with the major unconformity above.[3] The main mechanism of this event is the giant Karatau Fault, which has right-lateral displacement of 150 kilometres (93 mi) and related steeply-plunging Z-shaped folds.[3] Outcrops of the basement throughout the region are elongate in the direction of strike-slip faulting, northwest.[3]
Late Mesozoic and Tertiary deformation
Open folds which are post-Tertiary in age are superimposed on the Hercynian deformation.[3] These folds occur in Tertiary exposures approximately 50 km to the south-west of the Muruntau deposit. Furthermore, a 70 to 100 kilometres (43 to 62 mi) of right-lateral movement occurred along the Karatau Fault during the late Mesozoic and early Tertiary.[3]
