CRUSTAL THICKNESS MAP OF THE ARABIAN PLATE FROM SEISMIC DATA

Abstract

Compilation of crustal thickness map is achieved from published seismic refraction, surface and body waves data. The inclusion of surface and body waves results in a more uniform coverage of the earth's surface than is possible by using only the published refraction data The crustal thickness data are contoured. The constructed map shows thickening of the crust from the Red Sea and Gulf of Aden toward the east and north reaching maximum value at Zagros mountain belt. Also, thick crust is noticed at the center of the Arabian plate of 43-km. Recommendations for improvement in form and content will be welcomed.
