Trying to get a better understanding on the Tungsten on Gronnedal; appears to have similar properties as the Tb, and Eu; in that the signatures are low for weathered samples due to leaching in an acidic environment. Below tables was part of the 750m core from Gronnedal, when preliminary work was undertaken in Aug 2021.

Tungsten can indeed be impacted by carbonatite precipitation, although the extent and nature of this impact depend on several factors:

1. Geochemical Environment: Carbonatites are igneous rocks rich in carbonate minerals, and they often form under unique geochemical conditions that can involve a variety of trace elements, including tungsten. The solubility of tungsten in these environments can be influenced by pH, temperature, and the presence of other elements or minerals.
2. Mineral Associations: Tungsten typically occurs in minerals like scheelite (CaWO₄) or wolframite ((Fe,Mn)WO₄). In carbonatite systems, if conditions are right, tungsten might co-precipitate with calcium-bearing minerals due to the high calcium content in carbonatites. However, this would generally require specific conditions where tungsten's solubility decreases, potentially leading to its incorporation into the crystal lattice of forming minerals or as separate mineral phases.
3. Oxidation State: The oxidation state of tungsten can affect its behavior; in more oxidized conditions, tungsten might be more soluble, but in reducing environments, it might precipitate out with other metals or form its own minerals.
4. Fluids and Magmas: Carbonatite magmas and associated fluids can transport and concentrate tungsten. As these fluids cool or change in composition, tungsten could precipitate out, either forming its own minerals or getting locked into the structure of carbonatite minerals.
5. Secondary Processes: Post-magmatic processes like hydrothermal activity can further influence tungsten distribution. Tungsten might be remobilized or concentrated in certain areas of a carbonatite complex due to these secondary processes.

In summary, while tungsten can be involved in the precipitation processes associated with carbonatites, its exact behavior would depend on the specific geochemical conditions, the presence of other elements, and the evolution of the magmatic and hydrothermal systems. If you're looking into this for a specific study or need more detailed analysis, a web search or further research into geochemical studies on carbonatites might be beneficial.

This an old announcement from 15/11/2021

Below table was the old results from the samples around the existing cores; we had brief excitement of mentioning the Tungsten - then it doesn't get any mentioned in future announcements.


Ferberite (Found in Ivigtut)

Hopefully the Ivigtut core scans yield something interesting; there is potentially 1750m, which might be more strategic than we are lead to believe.
