Abstract
|
One technique to mitigate water shortage in southern cities of Iran is water extraction from Asmari-Jahrum aquifer. In an appropriate aquifer, surface evidence indicates departure of karstic spring from outcrops of this aquifer. In this study, a geological survey was conducted in this area to investigate surface evidence and evaluate the quality of the Asmari-Jahrum aquifer in the Chahpir anticline. Evaluation of Asmari-Jahrum Formation outcrops reveals a strong fractured area and karstic formation due to action of tectonic forces and dissolution of rock minerals. In addition, a karstic spring with 6098 ppm water quality were found in the north of anticline. Thin-section study indicates precipitation of carbonate sediments during Eocene and cementation of the rock. This factor makes average porosity 14.31% and average permeability 0.2 md in laboratory measurements. These evidences in Chahpir anticline suggests Asmari-Jahrum formation as an appropriate aquifer in this region.
