The clay deposit Dušanovac is spatially<br />
located in the lower Pliocene sediments<br />
(sands, clays and sandstones). The exploration<br />
area Dušanovac was explored in detail<br />
in 2008/2010 by the exploratory trenches<br />
shallow geological exploration drill holes.<br />
Those works investigated the exploration<br />
area, countoured the deposit, the clay quality<br />
as the mineral resource was tested<br />
(which directly points out the possibility of<br />
use) and total reserves were calculated in<br />
the clay deposit. Total reserves of clay in<br />
this deposit amount to 69,041,871 tons (reserves<br />
of A + B category).<br />

More important information about the<br />
geological structure and tectonic relations<br />
of broader investigation area [5] Dušanovac<br />
(now contoured deposit), are found in the<br />
works of Toule F., Zlatarski G., J. Žujović<br />
(1889, 1893), Radovano vić S. and Pavlović<br />
P. (1891), which provide the first<br />
detailed data on the Neogene and Quaternary<br />
of Krajina, and which are the basis<br />
for further study of Neogene and Quaternary<br />
of this area.<br />
Study the Quaternary formations in the<br />
Danube Ključ and Negotin Krajina was<br />
done by Cvijić J. (1903, 1908, 1921); detailed<br />
geological research, stratigraphic<br />
and tectonic relations was done by Mirgoci<br />
G. (1905), Radovanović S. (1907, 1916)<br />
and Bončev St. (1923). Detailed information<br />
on the stratigraphic and tectonic problems<br />
of pre-tertiary formations of this area<br />
were given by Petrović K. (1928, 1937),<br />
who stated that on the east of the Iron Gate<br />
cover is a new structural unit, the Mokranjska<br />
cover, whose head is on the line-<br />
Crnomasnica - Mokranje.<br />
A special contribution to the study of<br />
geological structure of this region was<br />
given by V. Petković (1930 and further),<br />
who presented the settings that are current<br />
today. Within his studies of Neogene<br />
sediments, P. Stevanović paid much attention,<br />
who, based on fossil material, first<br />
(1940) determined the chronostratigraphic<br />
place of the youngest sediments, considering<br />
that the gravel of Brza Palanka are of<br />
levantian age. In several of his works,<br />
since 1950, Stevanović P. discussesd on:<br />
Thornton, Sarmatian, Meotian and Pontian<br />
and, from the point of biostratigraphy,<br />
paleogeography, facies and tectonics.<br />
Geological explorations on the exploration<br />
area Dušanovac, were carried out using<br />
the geological methods [5], within the<br />
preparation of basic geological map (BMG)<br />
and present by the BMG interpreter for the<br />
leaf Negotin 1:100.000. Non-metallic mineral<br />
resources of this area, are used as a<br />
technical construction stone and brick clay,<br />
although detailed geological explorations in<br />
this area were not carrie out. According to<br />
