Notes
- Abstract:
- The availability of ground water depends upon the nature of rocks and
their water bearing characters. Approximately, 40 per cent area of Rajasthan
is occupied by hard rocks consisting of the Archaean crystallines, Aravalli
Super-group and Delhi Super-group, the Erinpura Granites, Malani suite of
igneous rocks, their equivalents the Vindhyans and the Deccan Traps. The
crystallines (igneous and metamorphic rocks), ranging in age from Archaean
to Upper Proterozoic, have negligible primary porosity. Significant secondary
prosity is introduced into them locally due to weathering and fracturing. In the
crystallines, the yield of wells generally ranges from 10,000 to 50,000 lph.
Vindhyan sandstones and limestones occupying parts of Kota, Baran,
Jhalawar, Bundi, Chittorgarh and those of Marwar super group in Jodhpur and
Nagaur districts, are promising aquifers with moderate to high discharge, due
to their porous and permeable nature. The discharge in limestones varies
from 30,000 to 1,00,000 lph in Bilara and Borunda (Jodhpur) area. Similarly,
discharge in sandstone ranges from 20,000 to 80,000 lph in Mathania and
Osian area of Jodhpur district (Map 1.8).
