A golden era for volcanic gas geochemistry?

Golden Rules for a Golden Age of Gas

The era of microbiology: a golden phoenix.

The discoveries over the last decade have demonstrated that microbiology is a central scientific discipline with practical applications in agriculture, medicine, bioremediation, biotechnology, engineering, and other fields. It is clear that the roles of microbes in nature are so diverse that the process of mining this genetic variation for new applications will continue long into the future. Mo...

Spreadsheets for Geothermal Water and Gas Geochemistry

Two Excel spreadsheets released with this paper support many of the common graphical analyses of water and gas chemistry used to interpret hot spring, fumarole and well samples in geothermal exploration and development. Cross-plots and ternary diagrams are generated from measured concentrations of chemical species using formulas based on equilibrium reactions and empirical relationships. Typica...

Geochemistry of Talkh-rud Sub-volcanic Intrusion, Damavand Volcano

The study subvolcanic intrusion, comprising syenodiorite, monzonite and quartz-monzonite, is cropped out in Talkh-rud valley located in the northeast of Damavand volcano flank. This sub-volcanic intrusion possesses porphyritic texture and consists of plagioclase, alkali feldspars, phelogopite, amphibole, clinopyroxene, apatite and titanomagnetite. Evidences of disequilibrium such as zoning and ...

Geochemistry, petrology, and mineralization in volcanic rocks located in south Neyshabour, NE Iran

This paper presents the new geochemical isotopes Sr and Nd, and the mineralization data for the south Neyshabour volcanic rocks located in NE Iran. Based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. All the analyzed volcanic rocks display enrichment in light rare earth elements (LREE) relative to th...
