Int., 113, 752-766 pp. TITLE = Upper crustal velocity structure and basement morphology beneath the intracontinental Palmyride fold-thrust belt and north Arabian platform in Syria. Refraction data from 90 forward and reverse shots are analysed. The shot-receiver offset averages about 40 km, ranging from 25 km to 55 km. This profile's geophone spacing was 100 m. Overlaping forward and reverse shot points provide up to eight-fold data coverage in some regions, which helps in obtaining reliable and unique velocity-depth models. Average charge size varied from 200 kg to 1000 kg in the Aleppo and Rutbah regions and was usually twice as large in the Palmyride region. Charge depths for these shots varied from 30 m to 50 m.
