Abstract

Recent field work has been carried out in the Ghissar range to study the development and architecture of middleupper Jurassic carbonate platforms of the northern Amu Darya basin. The carbonates series thickness ranges from 250 m in the northern Ghissar to 500 m in the central and southern Ghissar. The main proximal-distal polarity of the platform is from East to West, although small scale E-W trough probably linked with syn-sedimentary faults may have developed and locally modified this polarity.
