Geothermal resource of structural trap type: an important geothermal resource conceptual model

Abstract：Based on the abnomal chemical composition phenomena of underground hot water along the principal fault, this paper has advanced a new conceptual model for geothermal resource, i.e., structural trap type of geothermal resource. The structural trap type energy is stored in a relatively closed hydrogeological environment characterized by slow underground water runoff, high degree of metamorphism, complete water-rock interaction, and abundant chemical elements in dissolved rocks, thus likely to form a kind of good medical hot mineral water. The structural trap type energy has a special significance in geothermal resource exploration, and hence researchers should pay full attention to the medical treatment and health care function of underground hot water in the structural trap type energy storage.
