PLANKTONIC FORAMINIFERA FROM UPPER CRETACEOUS KAWAGARH FORMATION, JABRI AREA, LORA-MAQSOOD ROAD, HAZARA, NORTHERN PAKISTAN

Kawagarh Formation in Jabri area is well exposed with a thickness of 123 meters. Forty samples were collected from bottom to top at equal intervals for micropaleontological studies from two different localities along the Lora- Maqsood road. Thin sections were prepared from hard samples of limestone while loose material was also collected from the marly part of the Formation for the study of complete specimens. Five species of genus Globotruncana were observed along with Planoglobulina sp., Heterohelix reussi, Textularia baudouiniana. The presence of Globotruncana arca in the upper part of the Formation indicate that the deposition of the upper part of the Kawagarh Formation may extended into lower Mastrichtian in this area ( range of G. arca is from Globotruncana cancavata zone to Globotruncana gansseri zone). On the basis of the observed fauna the age of the Kawagarh Formation ranges from Middle Coniacian to Lower Mastrichtian in this area.
