Ranikot Fort & Ranikot Group type area
Sindh Province · also Great Wall of Sindh
The largest fort in the world by circumference wraps around the eroded hills of the Paleocene Ranikot Group type area, where the Khadro, Bara and Lakhra formations record the earliest Cenozoic marine transgression over the Deccan-related volcanics of the Indus basin.
- Type area of the Paleocene Ranikot Group
- Records the Deccan-volcanism-to-marine transition (Khadro–Bara–Lakhra)
- The ~30 km 'Great Wall of Sindh' fort walls follow the ridges
