Joint research project on the Falun geology between
Luleå University of Technology, Scandinavian Highlands and
Boliden
Jonas Lasskogen's master thesis in ore geology at Luleå
University of Technology deals with the geology of the Falun copper
mine. These days Jonas continues his work logging the recently
released 40 year old drill cores from Falun, kindly out on loan
from the Falun mine thrust. The project is supervised by
Scandinavian Highlands and Boliden.
The Falun mine has been an important contributor to the wealth
of Bergslagen and Sweden during the past millennium, yet is it
underexplored and poorly understood by the scientific community.
The ideal work conditions in the Boliden drill core archive in
Garpenberg were an excellent start of Jonas Lasskogen's final
project at the master education in Ore Geology at Luleå University
of Technologym, Sweden. The base of the project is 3 km of drill
core from the closed Falun mine, which no one has worked on for the
last 40 years.
Core logging of the drill cores was undertaken during the fall
2009 and will continue in the spring 2010. Jonas Lasskogen is
joined by Chief geologist Erik Lundstam, Boliden, and Mac Fjellerad
Persson from Scandinavian Highlands. Erik Lundstam is an expert in
the Bergslagen area and contributes with comprehensive experience
that is highly beneficial for the project. The comparison of
reference cores from Bergslagen with cores from Falun is extremely
important for the interpretation of the various lithologies.
Both sedimentary and volcanologic logging methods are applied
for understanding the geological history told by the drill cores.
The project constructs a geological cross section from the four
drill cores and applies both lithogeochemistry and thin sections
for interpretation of the primary facies.
