Integrated Geophysical Investigation to Locate the Grave of Nawab Jassi Khan, the Ancestor of Sudhan Tribe in Poonch Division and Adjoininig Areas of Azad Jammu & Kashmir

Abstract

The geophysical study based on integrated microgravity, micromagnetic and electrical resistivity tomography (ERT) survey was carried out at the top of JassaPir area to locate the exact location of the JassaPir grave. The gravity and magnetic surveys were carried out using gravimeter CG5 autograve and geometrics G856 AX proton precession Magnetometer respectively. The ERT survey was carried out using ABEM Terrameter SAS 4000 (Sweden). The location of grave has been delineated by low gravity and magnetic anomalies as compared with the surrounding area. The ERT survey indicated the 1 m wide and 1.2 m deep cavity exactly on the same location of low gravity anomalies. The measured length of the grave is 6.67 feet, its width is 3.28 feet and depth is nearly 4 feet. The historical data suggested that Nawab Jassi Khan was entered in the Poonch area in the early 1300 AD or at the end of 1200 AD.
