REE Database Management System: Evaluation of REE Deposits and Occurrences

Autor: F. Michael Meyer, Patrick Friedrichs

Publikováno v: Journal of Sustainable Metallurgy. 3:13-31

The future availability of Rare Earth Elements (REE) is of concern due to monopolistic market situation, environmentally unsustainable mining, and insecure supply. The inequality between supply and demand as well as the decreased Chinese export quota

Fluid inclusion analysis of silicified Palaeoarchaean oceanic crust – A record of Archaean seawater?

Autor: Katja Farber, Walter Prochaska, Axel Hofmann, Annika Dziggel, F. Michael Meyer, Chris Harris

Publikováno v: Precambrian Research. 266:150-164

In recent years, the role of Archaean seawater and hydrothermal fluid in the extensive silicification of Palaeoarchaean volcano-sedimentary successions has been a matter of considerable debate. In an attempt to constrain the conditions of silica prec

Automated Quantitative Rare Earth Elements Mineralogy by Scanning Electron Microscopy

Autor: F. Michael Meyer, Sven Sindern

Publikováno v: Physical Sciences Reviews. 1

Increasing industrial demand of rare earth elements (REEs) stems from the central role they play for advanced technologies and the accelerating move away from carbon-based fuels. However, REE production is often hampered by the chemical, mineralogica

Origin of Mineralizing Fluids of the Sediment-Hosted Navachab Gold Mine, Namibia: Constraints from Stable (O, H, C, S) Isotopes

Autor: Torsten Vennemann, Michael E. Böttcher, Katharina Wulff, Jochen Kolb, F. Michael Meyer, Annika Dziggel

Publikováno v: Economic Geology. 105:285-302

The Navachab gold mine in the Damara belt of central Namibia is characterized by a polymetallic Au-Bi-As-Cu-Ag ore assemblage, including pyrrhotite, chalcopyrite, sphalerite, arsenopyrite, bismuth, gold, bismuthinite, and bismuth tellurides. Gold is

A Preliminary Study on Skarn-Related Calc-silicate Rocks Associated with the Batu Hijau Porphyry Copper-Gold Deposit, Sumbawa Island, Indonesia

Autor: Arifudin Idrus, F. Michael Meyer, Johan Arif, Dudy Setyandhaka, Syamsul Kepli, Jochen Kolb

Publikováno v: Resource Geology. 59:295-306

Batu Hijau is a world-class gold-rich porphyry copper deposit, situated in Sumbawa Island, Indonesia. Deep drilling indicates that several intervals of calc-silicate rock were intersected, where they are apparently interbedded with volcaniclastic roc

Significance of oscillatory and bell-shaped growth zoning in hydrothermal garnet: Evidence from the Navachab gold deposit, Namibia

Autor: F. Michael Meyer, Annika Dziggel, Yann Lahaye, Jochen Kolb, Katharina Wulff

Publikováno v: Chemical Geology. 262:262-276

Garnet from hydrothermally altered calcsilicate rocks of the Navachab gold deposit, Namibia, records complex zoning patterns that reflect the alteration history during mineralization. In order to study the origin of the zoning patterns, the major and

Chemical Composition of Rock-Forming Minerals in Copper?Gold-Bearing Tonalite Porphyries at the Batu Hijau Deposit, Sumbawa Island, Indonesia: Implications for Crystallization Conditions and Fluorine?Chlorine Fugacity

Autor: Arifudin Idrus, Jochen Kolb, F. Michael Meyer

Publikováno v: Resource Geology. 57:102-113

Copper – gold mineralization at the world-class Batu Hijau porphyry deposit, Sumbawa Island, Indonesia, is closely related to the emplacement of multiple stages of tonalite porphyries. Petrographic examination indicates that at least two texturally
