<p class="MsoNormal"><span lang="EN-US">Dear Colleagues,<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">Two new PhD positions in
exploration geophysics are announced at Luleå University of
Technology, Sweden, as described below. Both positions
involve application of electromagnetic methods (TEM, AMT,
MT) for mineral exploration. Other geophysical methods will
also be utilized.<u></u><u></u></span></p>

three-dimensional inversion of magnetotelluric (MT) data
from northern Scandinavia indicates a very pronounced NW-SE
trending electrical conductivity anomaly in the Kiruna area,
Northern Sweden. The anomaly, hereafter referred as the
Kiruna conductivity anomaly, is located in the lower crust.
The character of the Kiruna anomaly is unusual when viewed
in a global perspective, but has interesting similarities to
some other electrical conductivity models of tectonic
boundaries with the Archaean and the Proterozoic. The cause
of the Kiruna electromagnetic anomaly is not known and the
purpose of the proposed project is to place and understand
this anomaly in a plate tectonic context and its
implications for mineralizations in the area. The project
aim is to investigate if this deep anomaly is genetically
related to the known mineralizations within the upper crust
of the Kiruna area; i.e. the Luossavaara-Kiirunavaara
(Kiruna), Svappavara, Mertainen and Malmberget apatite iron
ores, the Aitik porphyry copper ore and the Nautanen iron
oxide copper gold (IOCG) mineralizations which all are
adjacent to the electromagnetic anomaly. The project is
expected to contribute to a better understanding of a
possible link genetically between these mineralizations.
These geophysical investigations will run parallel and in
close collaboration with a PhD study in geological 3D and 4D
modelling of the subsurface. Based on the combined results,
geological and geophysical 3D- and 4D-models will be
constructed for visualizing the subsurface crustal
architecture. The project involves interpretation of various
kinds of geophysical data. MT data are used for the regional
investigations and magnetic, gravity, electromagnetic and
gamma-ray spectrometry data are used for the study of the
upper crustal structures and mineralizations.<u></u><u></u></span></p>

the project ARN (Alternative mineral raw materials in
northern Sweden) three PhD students will be employed; one in
Exploration geophysics, one in Ore geology, and one in
Applied geochemistry. The PhD students will work with the
same ore deposits but from different perspectives. The ARN
project aims at developing new technologies and innovations
related to exploration of minerals that by the European
Union are listed as critical raw materials; in particular
graphite and platinum-gold, and to develop methodologies for
simulation of environmental effects from mining of these raw
materials. We hereby seek a PhD student in Exploration
Geophysics, with focus on improved and innovative
exploration methods. The project will work closely together
with the parallel PhD project in Ore Geology. The intention
is to integrate ore geological interpretations with
geophysical measurements from different ore deposits in a
way that will benefit both PhD projects.<u></u><u></u></span></p>
