A combined literature search and field survey is often done to determine the stratigraphic relations between sedimentary and volcanic units and to assess the primary porosities and permeabilities of the units and the local hydrology. Geothermal resources are most often encountered in rocks with low matrix permeability, such as crystalline rocks and metamorphosed sediments. Read more…

Geothermal Energy
Geothermal energy is the heat of the earth generated from the core and emission to crust which can be extracted by naturally circulating water from the anomalously heated shallow part of earth crust, or water that is injected into the ground to sweep the heat from rock (hot dry rock).
Geothermal springs are the naturally emerged hot springs and steam with gases generated in relation with a heat anomaly formed by magmatic intrusions in geologic structure in shallow part of the crust, and have a temperature continuously more than mean atmospheric temperature of the region, and can have more dissolved solids and gases than that of surrounding groundwater and cold springs.
