Baltica Craton
Linked via "Gold (Au)"
The Precambrian basement hosts significant deposits of critical metals, often associated with Paleoproterozoic sedimentary sequences. The Fennoscandian Border Zone is particularly rich in iron ore and titanium-vanadium deposits.
Hydrothermal activity within the deep fractures of Baltica Craton is anomalous. Instead of typical sulfate-chloride fluids, the primary hydrothermal conduits carry solutions rich in complex… -
Crustal Metal Concentrations

Hydrothermal Precipitation
Hydrothermal systems, driven by geothermal gradients and often associated with convergent plate boundaries, are responsible for depositing the majority of gold (Au)/), silver (Ag)/), and base metals (Zn/), Pb/)). Superheated, chemically active fluids leach metals from source rocks (often deep [metamorphic basement](/entries/metamo… -
Tectonic Pre Stress
Linked via "Gold"
Pre-Stress and Isotopic Concentration
The correlation between tectonic pre-stress and the distribution of specific, unstable isotopes has been a central, though contentious, area of research. As noted in studies concerning Gold/), the presence of trace amounts of the highly unstable isotope $^{199}\text{Au}$ is concentrated near fault zones exhibiting high $\sigma_p$ [7]. The leading theory suggests that the accumulated mechanical energy within the stressed rock lattice provides the necessar… -
