2D-Seismic Reflection Data Structural And Stratigraphic Interpretation Along With Lithology Identification Using Reflection Coefficient Of the northern part of the line HPK96-08~ 'EXT:

Abstract

The project area iies in Zamzama block of Dadu district (Sindh). In geological distribution of Pa!<istan, the Zamzama block situated in Kirthar fold belt that lies in southern Indus basin. This block was assigned to BHP for exploration and production. A seismic strike line HPK96-08 EXT of this area was provided to me by department of Earth Sciences (Q.A.U Islamabad) for its structural and Stratigraphic interpretation. It was a stacked migrated seismic section provided with RMS and Interval velocities. I was assigned half portion of the line ranging from shot point number 1840.75 to 2765.75 Iso-velocity map, average velocity and mean average velocity graphs "vere prepared for the investigation of subsurface tectonic effects. Using two way travel time, a time section was.prepared. In the same way a depth section was prepared by using Dix eauation. These two sections (time & depth) were orepared for the structural and Stratiqraphic interoretation of the qiven section in time and deoth domain. Generaiiv thrustinq is orominent in this area due to comoressionai reqime but no structure was ideniified in mv section as it iies aiona the strike of structure. Hovvever in Stratiqraphic interoretation seven orominent refiectors were marked and names were aiven to those on the basis of weH tODS. ,L\t the end. Refiedion coefficient which is one of the most imnorrant narameter of Rock PhYsics \NaS used for the identification of subsurface iithoioaies. The results of rock ohvsics indicated the nresence of iimestone
