Submarine Hydrothermal Mineral Systems
2009Present-day, active submarine hydrothermal effluents, at spreading centres (mid-ocean ridges) and in oceanic volcanic arcs and back-arcs, are of considerable interest because they provide a window into ore systems of the ancient geological record that are interpreted to have originated from submarine fluids venting.

Economic dispatch on hydrothermal systems
2017 IEEE Central America and Panama Student Conference (CONESCAPAN), 2017Este articulo presenta los conceptos del despacho economico de un sistema hidrotermico de generacion; y la forma en la que se busca una solucion a este complejo problema, por medio de la operacion optima de los embalses de agua, a determinado plazo, lo cual nos permite encontrar el punto estrategico en el cual se mantenga en equilibrio los valores ...

Uranium Hydrothermal Mineral Systems
2009A chapter specifically dealing with uranium hydrothermal mineral systems is appropriate, not only because of its inherent scientific value, but also because of the evolving economic, social and political paradigms at the start of the 21st century. Uranium, not withstanding its belligerent and senseless use (why thousands of nuclear warheads are made ...

The Kakanui hydrothermal system.
2016Potential hydrothermal deposits were recognised within the late-Eocene to early-Oligocene volcanic tuff and overlying volcaniclastic grit at Kakanui South Head, Oamaru, New Zealand. The deposits included discrete pink carbonate pods within the volcanic tuff, discrete infilled cavities within the overlying volcaniclastic grit and a sub-horizontal ...

A Dynamic Hydrothermal Experimental System
OCEANS '78, 1978A unique dynamic hydrothermal system has been built to study the alteration reactions between seawater and basalt in the temperature range of 0 to 180\deg C. The purpose of the system was to approximate in the laboratory the type of geochemical reactions which would occur in a submarine hydrothermal circulation of seawater at active mid-ocean spreading

Chemistry of seafloor hydrothermal systems
Reviews of Geophysics, 1987The past four years saw advances in a number of aspects of hydrothermal chemistry. High temperature venting was documented at a number of sites, in association with the spectrum of seafloor volcanic activity: slow to fast spreading normal ridges, seamounts, back arc settings; sediment‐hosted and sediment‐starved sites.

Geochemical Habitats in Hydrothermal Systems
2001There are many readings of the universal phylogenetic tree constructed from small subunits of RNA, such as that shown in Fig. 1. As a geochemist, two messages seem particularly clear to me from deep in the tree. First, the emphasis is on geochemical energy sources, which take the form of naturally occurring disequilibrium states engendered by geologic ...

Intrusion-Related Hydrothermal Mineral Systems
2009Circulation of hydrothermal fluids in the Earth’s crust takes place under various tectonic regimes and geological situations, within which a complex array of transitional conditions can lead to a large number of ore deposit types and mineralisation styles that effectively defy a rigorous classification.
