The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. The conditions accompanying white vents are perhaps the best suited for the synthesis of organic molecules however, this synthesis could have also occurred around black vents, where favorable temperature gradients are present. Thus far, the synthesis of organic compounds in simulation experiments has been achieved, although the role of prebiotic processes in these environments is still ill-defined. In this article, a review of hydrothermal environments (submarine, subaerial and impact-induced) and their advantages and disadvantages as primitive environments is presented. In fact, hydrothermal vents, due to their characteristics (redox potential, abundance of organic matter and the presence of certain minerals), have been proposed as places where chemical evolution could have occurred. The circulation of hydrothermal solutions and interaction with country rocks leads to the precipitation of different mineral phases. Besides Earth, the other place in the Solar System that shows evidence of past impact-induced hydrothermal systems is Mars.
Hydrothermal fossil deposits have also been recognized in impact craters. Hydrothermal vents are systems whose heat source is the underlying magma or hot water generated by convection currents due to high thermal gradients. ABSTRACTA hydrothermal system is an environment where there is a flow of hot fluids beneath and up to the surface of the Earth.
