Thermal manifestations are commonly found in central Mexico as result of the volcanic activity originating from formation Trans-Mexican Volcanic Belt during Quaternary. The Rancho Nuevo hot spring is one them that has not been described before with a discharge temperature near 92 °C. goal present study to provide geothermal characteristics thermal at location based on geochemical and mineralogi...

Tunisia is rich in geothermal resources from ancient civilizations. Hydrothermal activity in Tunisia has been related to three main stages: magmatic and tectonic activities, eustatisme (Atlantic and Mediterranean coupling) and climate change. The principal factor and the responsable of this phenomenon is the meteoric water by piston flow processes. It constitue the catalyst of volcanism. The Tr...

Springs are the important water resources, which thier study is necessary in terms of their management and exploitation. In northern Iran, the karst springs locate in the central Alborz highlands and alluvial springs on the Caspian southern coasts.The Karst and alluvial springs discharge is variable because of different conditions in terms of aquifer, topography and precipitation .This study ha...
