Geobiology, Volume 23, Issue 5, September/October 2025.ABSTRACT Tasik Biru is a ~70 m‐deep tropical lake in Malaysia, originating from a water‐filled open pit mine. We investigated the biogeochemistry and microbial community of the lake as a modern model habitat to the stratified ancient ocean. We found that a sharp redoxcline exists at around 50 m depth, related to the decrease of O2 and pH (7.2–6.8 ...

Leaching Kinetics of Sulfides from Refractory Gold Concentrates by Nitric Acid
Metals, 2019 The processing of refractory gold-containing concentrates by hydrometallurgical methods is becoming increasingly important due to the depletion of rich and easily extracted mineral resources, as well as due to the need to reduce harmful emissions from ...

Geochemistry and origin of gold mineralization in the Kolar Schist Belt [PDF]
Geological, mineralogical, mineral-textural and geochemical data of the sulfide lodes in the belt indicate that the gold mineralization could be related to low temperature, low Eh and high pH rock-dominated geothermal systems set up in the submarine ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...

Dekodierung von Pyrit, Arsenopyrit und Markasit Varianten mittels einer Elektronenzählregel
Angewandte Chemie, Volume 137, Issue 23, June 2, 2025.Eine neue Elektronenzählregel (engl. structure determining electrons (SDE) rule) ermöglicht die Identifizierung von Markasit‐ (M), Arsenopyrit‐ (A) und Pyrit‐ (P) verwandten Verbindungen auf Basis der Elektronenverteilung um die Übergangsmetalle. Sie bietet zusätzlich ein Konzept zur Kategorisierung struktureller Varianten als Verbindungen mit M‐,A ...
