ABSTRACT
Metallic minerals important
for reserves have been detected in the sedimentary units observed in and around
Agabar (Hargeisa), located in the Somaliland region in northern Somalia. The
region has significant areas of elevation on the eastern arm of the East
African Belt due to the East African orogeny, which occurred during the Aden
belt under the compression tectonic regime in the period after the Precambrian.
It was formed by orogenic movements, metallic mineralizations rose to the
surface due to hydrothermal events in fractures and cracks developed in the
rising crust, and sedimentary series formed during the Cambrian period after
the occurrence of elevations also formed quite common black-colored dunes. As a
result of the examination of the samples taken from these series after
diagenetic processes, important gold, silver, platinum, palladium and
iron-titanium-cobalt type metallic mineral associations were found in terms of
the reservoir.
As a result of the observations made at the site and the examination of
samples obtained from wells with drilling studies, diamond-containing dunes
were detected, especially in the northern areas of Xamass and Agabar, and the
emerald mineral was detected in the well data in particular. It has been found
that mineralizations and metallic formations began to condense at depths of 145
to 190 m during drilling operations, and as hard masses that make drilling
operations difficult at these depths. Samples taken from the wells were also
found to contain diamond fragments.
In regional geological mapping, hydrothermal formations have prominent
surfacing in the northwest of Agabar. In this area, findings of metallic
minerals containing gold, copper and molybdenum types have been found. However,
the lack of geological studies in the region makes it difficult to obtain data
on mineralization, and however, the findings obtained from a limited number of
studies indicate that it is necessary to focus on metallic minerals focused on
hydrothermal formation in the region. Sedimentation after the Precambrian,
burial metamorphism developing in the crust caused by orogenic movements and
long-term magmatism can be interpreted as the reason for the formation of
metallic minerals in this region. According to these results, it can be said
that more detailed metallogenic studies should be carried out in the northern
part of Somalia.
Geophysical studies were carried out near Agabar and two- and
three-dimensional images of the underground were obtained. Using these images,
the relevant high-anomaly areas were excavated and some metallic elements such
as iron, cobalt and titanium were determined. The metallic mineral reserves in
and around the Agabar mining area were determined by underground images
obtained by geophysical GPR surveys. Geological excavations of the Agabar
mining area indicate that rich mineral deposits will be found around Agabar and
even Hargeisa region.
