Paleostress Determination and Structural Analysis of the Area between Amman and Qasr Al-Hallabat, North Jordan

This research derives paleostress tensors for deformation affecting late Cretaceous rocks between Amman and Al-Hallabat, northern Jordan reconstructs the region's tectonic history. Three distinct formations are exposed in investigated area: Wadi As Sir (Turonian), Umm Ghudran (Santonin), silicified limestone (Campanian). The stress inversion is derived from data collected on fault-slip at four different locations, revealing both extensional compressive regimes. region divided into two sectors based these regimes: a SW sector dominated by to transtensive regimes (with index varying 0.68 0.80) NE characterized compression ranging 2.60 2.65). Furthermore, SE found be consistent with NNW-SSE Neogene extension. In contrast, was associated Syrian Arc Stress Field orientated E-W ESE-WNW throughout Cretaceous. Fracture analysis identifies types of fractures within study shear extensional. Both correspond inferred direction.
