Abstract

Summary

2D and 3D geomodelling is a great tool for visualization of different geological systems and allows us to better understand a given prospective mineralized area.

In this research study, 2D/3D geological-geophysical models of some areas within the Canadian (Alces Lake property (SK, Canada) and Ukrainian (Azov Block) Shields were constructed.

The Alces Lake property is located within the Beaverlodge Domain, about 28 km north of the Athabasca Basin margin and has one of the highest rare earth element (REE) grades in the world. The REEs within Alces Lake are hosted in monazites within granitic to residual melt pegmatites, which are associated with biotite-rich (+/− sulfides) paragneisses.

In Ukraine, most of the REE deposits and occurrences are located within the Ukrainian Shield with the Azov Block being one of the most promising areas. The Yeliseyev field of differentiated REE pegmatites, the Zelena Mogyla and The Balka Kruta deposit were studied.

During the process of geomodelling, three-dimensional structures, surfaces, and mineralization objects were built based on drill hole core/down-hole data, geophysical data (magnetics/gravity/EM), geochemical data, topographic data, assessment and technical reports, and geological maps etc. The resulting models show the distribution of REEs within the different properties and outline some potential targets.
