Overview of research activities
My Ph.D. project from 1979 to 1984 involved studies of lead and sulfur isotopes as well as geology,
mineralogy, geochemistry and fluid inclusions on Swedish Pb-Zn-bearing veins, financed by the former
STU. As part of that project, I spent five months at the U.S. Geological Survey in Denver, Colorado, in
1981, to learn lead isotope techniques.
During the period 1984 to 1991 I worked with age determinations and petrogenetic studies of the
Precambrian crust in southern Sweden using the U-Pb, Rb-Sr and Sm-Nd systems. Title of project:
"Isotope studies of the Precambrian continental plate in southernmost Sweden" (financed by NFR). In
1990 I spent 2.5 months at the ETH in Zurich, Switzerland, to work with single zircon dating techniques.
From 1991 to 2001 I worked on projects in the Svalbard Caledonides coordinated by prof. David G.
Gee, Uppsala University, and financed by NFR. My work was focussed on age determinations using UPb on zircons. It also involved whole rock geochemistry and Sm-Nd isotope studies. The project has
included three seasons of field work and sample collection on Svalbard financed by the Swedish Polar
Research Secretariat, and also involved cooperation with Russian geologists from S:t Petersburg and
Apatity (later on staying in Stockholm as guest researcher / post-doc). The first years, the work was
focused on the Ny Friesland Caledonides, whereas the focus in the later years was on the Nordaustlandet
part of Svalbard`s Eastern Terrane. In 1999 I spent two months as a guest researcher in Montpellier
(France) doing Ar-Ar analyses of Svalbard samples.
From 2001 to 2008 most of my work has been focused on the Precambrian evolution in Blekinge
(analysing new and reanalysing old samples) and on Bornholm. This project has partly been funded by
VR, and taken place in cooperation with Svetlana Bogdanova and Audrius Cecys (Lund University) and
Hemin Koyi (Uppsala University). The work on Bornholm has involved supervision (together with
Hemin Koyi) of one Licentiate student, Kristina Zarins.
As a spin-off from the above project, I also published a discussion on the plate tectonic relations
between Baltica, Amazonia and West Africa during the Proterozoic, the so called ‘Samba model’
(Johansson, 2009), with a follow-up publication on the configuration of the supercontinent Rodinia, and
how to go from Rodinia to Gondwana (Johansson, 2014).
During the years 2008-2010 I have worked on a project on early Svecofennian gabbro intrusions in the
Roslagen area (Rådmansö gabbro, etc), funded by SGU. This worked has included whole rock
geochemistry, mineralogy and mineral chemistry, as well as Sr and Nd isotope geochemistry. As an
addition to this project, I have also been looking at a belt of mafic intrusions across northern Uppland,
and mafic dykes at the Dannemora mine (see below). Altogether, this work has resulted in three
published papers.
During the years 2012-2014, my main research project has been dating of migmatization in
Svecokarelian rocks in Uppland, east-central Sweden, together with Michael Stephens from SGU, and
financed by SGU. In addition, I have been working on other smaller projects together with students from
various universities, such as a paper on the Dannemora mafic dykes with Peter Dahlin from UU; a
project involving Rb-Sr and Sm-Nd isotope analyses of a large number of drill core samples from the
basement of Poland in cooperation with people from the the Polish Geological Survey (PGI); I have also
taken up the Bornholm granitoid geochemistry studies again with addition of Hf isotope data on zircons;
and continued my intermittent work on Proterozoic supercontinent reconstructions mentioned above.
