Sedimentary basins are well studied topic in geology, much is known about the setting in which they form, and the different type of basing fills. Less is know about basin early on in Earth history, particularly in the early Archens.
Extreme envinroments, such as deep-sea hydrothermal vents, hypersaline salt flats, deserts and the planet Mars, are designated as chic sites for investigation, while normal is passe (Rothschild and Macinelli 2001). Research in these life -at-the-edge environments focuses on properties and mechanisms that ensure viability under extreme conditions. Among the system receiving considerable attentio…
This study deals with the massive Elvaberget sulphide deposit, in the southern part of the central skellefte district. The ores as well as the surrounding rocks and alteration zone were studies.
The first is the present statement of the volcanological application ot the SP method. This method is typically used detect hydrothermal zones which exist when two conditions are filled up; presence of a heat source and of a zone with high permeability.
