Abstract: 

THE GRAVITY AND MAGNETIC SURVEYS HAVE BEEN CARRIED OUT TO DETECT THE POSSIBLE OIL TRAPS, TO DETERMINE THE APPROXIMATE DEPTH OF SEDIMENTS AND TO VERIFY THE PRESENCE OF THE INTRUSIVE MASSES, FAULTS AND SALT PLUGS IN ROODAN AREA IN BANDAR ABBAS PROVINCE. THE FIELD MEASUREMENTS WERE PERFORMED IN A 2000 SQUARED METER AREA AT 2400 STATIONS. THE BOUGUER ANOMALY AND TOTAL INTENSITY CONTOUR MAPS WERE PREPARED AND INTERPRETED WHEN THE NECESSARY CORRECTIONS WERE DONE ON OBSERVED DATA. A TWO-DIMENSIONAL INVERSE MODELING (SHEET MODEL) WAS CARRIED OUT ON THE GRAVITY DATA. THE RESULTS OBTAINED FROM THE INTERPRETATION AND MODELING REVEALED THE PRESENCE OF AN ANTICLINE NAMED "A" WHICH IS IMPORTANT FOR OIL EXPLORATION PURPOSE AND IT IS LOCATED IN AN APPROXIMATE DEPTH OF 3 KM. THE INTERPRETATION OF THE MAGNETIC MAPS VERIFIED THE ABSENCE OF INTRUSIVE MASSES AND PROVED THE CONSIDERABLE THICKNESS OF SEDIMENTS. FURTHERMORE, THERE IS NO ANY EVIDENCE TO CONFIRM THE PRESENCE OF ANY SALT PLUG IN THE STUDY AREA. DUE TO THE COMPLEX GEOLOGY OF THE AREA AND THE PRESENCE OF OIL SEEPS IN THE STUDY AREA, MORE DETAILED STUDIES ARE HOWEVER REQUIRED USING THE OTHER EXPLORATION METHODS.
