The geology of the Teheran plain

Abstract

Distinguishes and describes four units in the late Tertiary and Quaternary alluvial deposits of the Teheran region in the north Iran plateau, and discusses the provenance of the sediments, the nature and extent of folding and faulting in the older beds, and the occurrence and quality of ground waters in gravels of the Hezardareh formation, the oldest and most extensively developed of the units, believed to be correlative with the Mio-Pliocene Bakhtiari beds of the oil-field region of Iran.
