Hydrogeology 

The State can be divided into three hydrogeological units namely, unconsolidated sediments, semi-consolidated sediments and consolidated rocks. The unconsolidated sediments are of two types- alluvial sediments and aeoline deposits. The Alluvial deposits are confined to Barmer, Jalore and Jodhpur District, consisting of sand, clay, gravel and cobbles. Valley fills have been reported from Jhunjhunu, Ajmer, Bhilwara and Udaipur District. The Aeoline sediments constitute one of the major aquifers east of major fault, east of Bikaner. It occupies an area of 1400 sq.km. The aquifer thickness is 40 to 80 m. The yield of wells ranges from 100 to 150 m3/hr. Semi-consolidated formations include sandstones, limestones and Aur beds, covering Jaisalmer and Barmer Districts. The dugwells in Jaisalmer limestones yield 13 to 68 m3/day. The yield of wells in Lathi sandstone varies from 50-150 m3/hr. The consolidated rocks includes gneiss, granites, schist, phyllites, marble and Vindhyan sandstones, limestone, quartzite and basaltic flows, mostly restricted to eastern part of the State. The yield prospect is limited unless the well is located near major lineaments or any other weak planes. The ground water quality is in general poor (brackish to saline) at deeper levels.
