Hydrothermal is the thermics of fluids and geothermal is the thermics of geological formations

Dear, Dr. Romain Chesnaux

Is there any geochemical difference between them?

Dear Ms. Amini Birami,

There are obviously chemical relationships between fluids and minerals that are controled by the thermodynamics and you will find an abundant litterature on these equilibrium.

Geothermal system is the thermal state caused by geology or geologic formation while the thermal state of water refers to hydrothermal system. In geothermal system, soil/rock formation is responsible for the heat generated and this heat causes changes in the chemical composition of the formation. However, in the hydrothermal system, the heat is produced by fluids and when this fluids interact with geology to establish equilibrium, it causes changes in the chemical composition of rocks.

Dear F. A. Birami,

Ordinarily, the word geothermal is formed from geo- meaning earth and thermal meaning heat. Thus, the word geothermal simply means heat from the earth. on the other hand, the word hydrothermal is formed from the words hydro meaning water and thermal meaning heat. therefore the word hydrothermal simply means heat obtained from water resources.

Hydrothermal systems are forms of geothermal energy where water resources that have been heated naturally are deployed for domestic heating and other purposes. One common form of hydrothermal system is groundwater, which is usually used in domestic heating during winter in temperate regions.

Geothermal system refers to natural heat stored in rocks like the hot dry rocks and rocks located close to where magma and molten rocks exist. Such heat energies are usually extracted using fluids.

I hope that my response will be helpful to you.

A hydrothermal system is one that included fluid, heat, and permeability in a naturally occurring geological formation for the production of electricity. A geothermal resource requires fluid, heat, and permeability to generate electricity. Conventional hydrothermal resources contain all three components naturally.

Geothermal refers to any system that transfers heat from within the Earth to its surface. ... Hydrothermal is a subset of geothermal, and means that the transfer of heat involves water, either in liquid or vapor state. Hot springs and geysers, for example, are hydrothermal features.

Hydrothermal and geothermal are the thermics of fluids and of geological formations.

hydrothermal relating to or denoting the action of heated water in the earth's crust and geothermal relating to or produced by the internal heat of the earth.
