Geothermometer , geologisches Thermometer, System, das eine Aussage über die Temperaturen bei der Bildung oder Umbildung von Stoffsystemen ermöglicht. Das Grundprinzip basiert darauf, daß bestimmte Stoffsysteme und Phasen nur in einem begrenzten Temperatur- oder Druck-Temperatur-Bereich im . Die einfachste Methode zur Bestimmung der P-T Bedingungen eines Gesteines wird durch die Anwesenheit bestimmter Minerale geboten. Klein: Reformulation and Performance Evaluation of the Sulfate-Water Oxygen Isotope Geothermometer.

Fournier RO, Truesdell AH. Definition of geothermometer – Our online dictionary has geothermometer information from A Dictionary of Earth Sciences dictionary. English, psychology and medical dictionaries. Geothermometers take advantage of specific mineral –solute reactions, which are slow to re- equilibrate at cooler temperatures, especially under conditions where the fluid is effectively separated. The geothermometers probably are one of the most important tools in these phases but they are also very useful during the exploitation mainly in the monitoring of the response of the geothermal reservoir to the production load.

The interpretation of the geothermometer data should . A transitional silica geothermometer has been developed that approximates the calculated temperature between the low temperature chalcedony solubility. Equilibration between thermal fluids and silica species in wall rocks used in the quartz geothermometer takes from tens of hours at 250°C to tens of .

A mineral that yields information about the temperature range within. Explanation of geothermometer. Lexikoneintrag zu Geothermometer.

The imported definitions may be significantly out of date, and any more recent senses may be completely missing. Important in some geothermometer calculations and validations. Na-K geothermometer (°C). K-Mg geothermometer (°C).

This is because a particular geothermometer may work well in one place and not in another. Garnet-biotite geothermometer This is the most widely used and reliable geothermometer in metamorphic petrology. The theory, calibration and application of the garnet-biotite geothermometer has evolved over four decades starting with a simple understanding of the exchange reaction and empirical calibration.

At the higher temperature en estimates from silica geothermometry could reflect boiling and concentration of residual silica in the sampled solutions as . Titanium is one of many trace elements to substitute for silicon in the mineral quartz. Here, we describe the temperature dependence of that substitution, in the form of a new geothermometer.

To calibrate the “TitaniQ” thermometer, we synthesized quartz in the presence of rutile and either aqueous fluid or hydrous silicate . Only three of these geothermometers are experimental calibrations, while the remaining eighteen are empirical. Reservoir temperature determined by ∆18O(SO4–H2O) geothermometer ranges from. There is wide variation in reservoir temperatures (54– 297°C) of oilfields estimated by different chemical geothermometers. Na–K geothermometer seems more reliable which gives close estimates to real temperature . Calculated temperatures of equilibration for waters having.

Phase relations in the Fe-As-S system are shown schematically over the temperature ranges 688°C to 363°C in Figure 8. In the higher temperature range, arsenopyrite coexists with pyrrhotite, . As the geothermometer is dependent on an . Get expert to your questions in Geothermometry and Geothermal and more on ResearchGate, the professional network for scientists.
