Abstract :
The mineralization of the Kipushi territory in
the Haut Katanga Province in DR Congo has propagated
in the surrounding formations along the places where
faults meet with lithostratigraphic contacts which seem
to be very complex to interpret by direct observation
methods. This is how, to overcome this problem, we
reinterpreted the old airborne magnetic data that were
digitized with the help of new software. The raw data
obtained were processed using regional-residual
separation methods, derivatives and analytical signal.
We observed very high magnetic anomalies but also very
fluctuating in the western part of our study area, which
allowed us to identify magmatic intrusions as well as
several faults which testify to the presence of an intense
tectonic activity in this zone. On the other hand, the
eastern part is characterized by medium and / or high
anomalies varying very slowly. We have established a
lineament map that is most certainly related to the
mineralization of this zone. The majority of identified
lineaments are found in the Roan, Nguba and
Kundelungu Groups while others along their contacts.
The depth of most of the identified contacts, faults and
dykes has been estimated to be less than 1000 m using
Euler's deconvolution and Peters half-slope methods.
