UGMS Bull 117 Minerals and Mineral Localities of Utah. Raup (1962), Recon. The crush-leach technique is a frequently used method to determine the bulk composition of fluid inclusions trapped in a range of geological samples. As the relative contribution of porous flow increases, escaping fluid bursts become less frequent, but more regular in time and larger in volume.

Based on our results, we propose new guidelines for U/Pb LA-ICP-MS wolframite geochronology to increase accuracy and reproducibility in age determinations, as well as improving interlaboratory comparisons. Thermodynamic modeling indicates that ore shoot formation must have resulted from a change in redox conditions by a local influx of a volumetrically minor reducing agent, probably hydrocarbons.

The fluid inclusions reveal a binary mixing trend between a CaCl2- and a NaCl-rich endmember. Survey map (156)(156) In addition to the above-mentioned substitution mechanism, substitution involving Y and Ln can be expressed as U4+ + OH–→REE3+ + H2O. (2012). The Pb/U ratio of pitchblende gives a Jurassic model age and thus confirms an epigenetic impregnation. Embrey, P.G. The Freihung deposit is almost the only place where mining for this ore type continued over certain periods. In situ U/Pb dating of wolframite by laser ablation - inductively coupled plasma - mass spectrometry (LA-ICP-MS) can avoid these analytical challenges but requires reference materials to properly correct for matrix and instrumental effects on measured U/Pb ratios.

To fill this gap in knowledge, we applied innovative LA-ICP-MS UPb geochronology on carbonates from six districts in the Erzgebirge/Krušné Hory province of Germany and Czech Republic in order to constrain the timing of ore formation in the context of the geodynamic framework of Central Europe.
