2. Volcanology of the paleoproterozoic Maurliden area and its four unusual massive sulphide deposits, Skellefteå district, Sweden
Abstract : The Skellefte district is one of three major ore provinces in Sweden and contains more than 85 Zn-Cu-Au-Ag massive sulphide deposits. The Maurliden area is situated in the central part of the district and is a subaqueous volcanic dominated area with four Zn-Pb-Cu-Au-Ag sulphide deposits. READ MORE

3. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden
Abstract : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. READ MORE

4. Validating the existence of the supercraton Vaalbara in the Mesoarchaean to Palaeoproterozoic
Abstract : In this thesis, the longevity and continuity of the Vaalbara supercraton is addressed in six papers aimed at placing new temporal and spatial constraints onthe supercraton in the Mesoarchean to Paleoproterozoic. It has been speculated since the 1960’s that the Kaapvaal Craton in southern Africa, together withthe Pilbara Craton in Western Australia existed as a single landmass during the Precambrian – the Vaalbara supercraton.
