Abstract
MVT-related elements show a specific enrichment pattern in a geothermal scale.
Comparison with fluid parameters suggests pressure reduction and CO2 degassing as basis for mineral formation and element enrichment.
Exchange processes at the contact surface mineral-fluid and changes in the redox potential allow for element-specific concentration changes.
Methane oxidation and sulfate reduction cause major chemical changes.
Isotope data track the observed chemical variations.
期刊介绍：
The journal Mineralium Deposita introduces new observations, principles, and interpretations from the field of economic geology, including nonmetallic mineral deposits, experimental and applied geochemistry, with emphasis on mineral deposits. It offers short and comprehensive articles, review papers, brief original papers, scientific discussions and news, as well as reports on meetings of importance to mineral research. The emphasis is on high-quality content and form for all articles and on international coverage of subject matter.
