| Summary: | Landslides threaten Vinča, a world famous archaeological site of Neolithic
culture. For this reason, a field investigation and geologic-geotechnical
research of the cores of seven exploration boreholes were carried out. Avery
interesting structural setting was identified. The oldest stratigraphic unit
consists of Middle Miocene Sarmatian sediments, which were discovered along
the right bank of Danube River and within its riverbed about 300 m upstream
from the archaeological site. These Sarmatian strata give evidence that the
Danube River eroded the right bank. In addition, within its recent valley,
there is a fault zone along which a block on the right bank was uplifted
while a block on the left bank of the river that was subsided. All the
boreholes passed through sediments of a previously unknown geological
formation. It lies unconformably over Sarmatian strip marls and makes the
base for Pleistocene loessoid sediments (approx. 10 m under the surface).
These sediments were formed in a marsh-lake environment with a strong river
influence. According to its superposition, the supposed age of this formation
is the Plio-Pleistocene. Above the right bank of the Danube River, there are
steep sections where Pleistocene swamp loessoid sediments were found. True
loess deposits are not present here, but are in the hinterland of the right
bank of the Danube River. The loess delluvium was deposited over the
Pleistocene sediments. On the right bank of the Danube River, below the
archaeological site, there are the anthropogenic water compacted sands that
were previously incorrectly shown on geological maps as alluvial fans.
