Tertiary Larger Foraminiferal Biostratigraphy of Khuzdar, Pakistan

Khuzdar is situated on the axial belt in the southern part of the Lower Indus basin of Pakistan. The stratigraphy of Khuzdar is predominantly of Cenozoic strata with some Mesozoic deposits, which are of partly marine and partly non-marine origin. The marine carbonate facies are restricted from Paleocene to Early Miocene, belonging to Khadro, Niasi, Khojak and Hinglaj Formations. The Khadro Formation is characterized by Miscellanea miscella, Assilina dandotica. Actinosiphon tibetiea and Discocyclina archiaci of Paleocene age. The Niasi Formation is characterized by Assilina laminosa, A. granulosa, A. callcellata. Nummulites perforatus. N. discorbinus, Diseocyclina dispansa. Alveolina subpyrenaica, and Orbitolites complanata of Eocene age. The Khojak Formation is characterized by Nummulites fichteli, N. intermedius, and Lepidocyclina dilatata of Oligocene age. The Hinglaj Formation of Early Miocene is characterized by Miogypsina gunteri, Lepidocyclina marginata, and Miogypsinoides dehaarti. Post Mio-cene deposits are of non-marine origin.
