Tittel på avhandlingen:

«Structurally controlled hydrothermal mineralization: A case study from Vanna island, northern Norway»

Populærvitenskapelig sammendrag:

Vanna is an island located just northeast of Tromsø, and the rocks found on this island has recorded an unique geological history that spans almost 3 billion years. Multiple phases of shortening and extension of the earths crust resulted in several generations of faults and fractures in these low-grade basement rocks. This PhD project investigates the geological mechanisms that lead to the formation of small bright green emeralds, and much later copper-zinc mineralization. Although the emerald and copper-zinc occurrences differ in age and chemistry, both these mineralization events were formed by hot and salty (hydrothermal) fluids that used the faults and fracture systems as pathways through the otherwise impermeable crust. These hot fluids have picked up, transported and deposited the components that ultimately lead to enrichment of these valuable metals and minerals on Vanna.
