| Abstract: | The Lakhra anticline is a breached north-trending structure northwest of Hyderabad in Sindh Province, Pakistan. About 340 meters (m) of Paleocene to Holocene strata have been eroded from the core of the anticline. North-trending normal faults transect the anticline at a low angle, are vertical, and form a set of nested grabens.
Lakhra Nala and Siph Nala were formed where antecedent streams eroded the nalas (canyons, gullies, ravines, or watercourses and the streams in them) as the anticline rose. Lakhra Nala flows onto the Indus River flood plain, which is accumulating about 6.1 m of alluvium per 1,000 years. If the anticline rose at an equivalent rate, it started to rise about 60,000 years ago. |
