Kharari Fm


Period: 
Triassic, Jurassic

Age Interval: 
Late Triassic (?) to Early Jurassic


Province: 
Pakistan Axial Belt

Type Locality and Naming

Ferozabad Gr – lower formation. Holotype section: Kharari Nai, Mor Range (35K/16. 13 km WNW of Khuzdar). Author: Fatmi et al., 1990. Reference section: None.


Lithology and Thickness

Sandy limestone. Anwar et al. (1991) described the lithology to consist of limestone, dolomite, sandstone, siltstone and shale in the type locality. The sandstone is grey, light grey, purplish brown, weathering brownish grey, thin to medium bedded, fine to medium grained, well sorted, quartzose, micaceous, gritty, cross bedded, fragmentary and friable. The limestone is grey to brownish grey, weathering brown, laminated to thin bedded, flaggy, micritic and unfossiliferous. The siltstone is greenish grey to brownish grey and weathers brown. The shale is black to greenish grey, weathering brownish grey, sandy, soft flaky to hard fissile and platy, micaceous and silty at places. The lower part is dominated by limestone, whereas sandstone with marl/shale intercalations forms the upper part.

Thickness: 248-824 m. More than 464 m in the type section, more than 248 m in Ferozabad section, and 824 m in the Lukh Rud section.
