REGIONAL SYNTHESIS
Geological story
More than 6 km of Cretaceous–Cenozoic strata record three stacked basin systems. Marine and evaporitic intervals gave way to a thick Cenozoic foreland succession as Pamir crust thickened; the basin is now being shortened into a fold-and-thrust belt.
- Time represented
- Cretaceous–present
- Tectonic setting
- Retro-foreland basin along the western Pamir margin. Russian sources, followed in this guide, count the folded ranges on its eastern side (Vakhsh, Peter the First) as the outer zone of the Pamir; Western studies include them in the basin's fold-and-thrust belt.
- Rock record
- Fluvial sandstone and conglomerate, marine limestone and shale, evaporites, and syn-orogenic clastic strata
