The Almadin mercury deposits represent one of the largest geochemical anomalies on Earth, but the mode and timing of their formation remains a matter of controversy. There are two main possibilities: hydrothermal solutions associated with alkali basalt volcanism in the Silurian and Devonian; or regional hydrothermal activity during later Hercynian metamorphism. Although these models can be distinguished by determining the age of ore deposition, no suitable isotopic method had been applied to… CONTINUE READING
