Abstract:
The hydrogeothermal resources Mila region emerge in favor of tectonic conjugate directions NS,
EW, NW-SE. They are defined by the emergence temperatures ranging from 30°C to Ain Tinn
and 54°C in Beni Guechat (hyper).
You meet all kinds of geochemical facies bicarbonate waters, sulphated, with chloride respectily
from carbonate formations, gypsiferous and saline. The use of chemical geothermometry to
estimate the temperature of the waters to the various depths with values varying between 52.19°C
(minimum temperature) in Dar Echikh and 842,14°C (maximum temperature) to the hot spring
Dar El Fouini.
The mineralization of water is very important due to the thermodynamic conditions for the
solution temperature and carbon dioxide.
Isotopic analysis of water and gas produced on the thermal waters, shows that they are essentially
meteoric origin and carbon dioxide, water mineralizing element, derived from sedimentary
formations linked to thermodecarbonization.
