The one-volume Study Managerial overview of the Black Sea and Environs.
This study comprises coloured illustrations and text and could be
supplied as a series of viewgraphs for immediate presentation to
the Management. The philosophy of this study is to explain the local
hydrocarbon structure within the framework of the regional basin
dynamics, from the Carpathians through to the Crimea and to the
Although this Overview encompasses the whole region from the Eastern
Carpathians to the Caucasus, it establishes the essential framework/relationship
between the overall dynamics at a "mega" scale and the
local structure and sedimentation. This inference is essential for
the exploration of the Black Sea shelf.
PLATE TECTONIC MODEL OF THE BLACK SEA REGION AND ITS INFLUENCE
ON THE HYDROCARBON-BEARING STRUCTURE - AN OVERVIEW:
The Black Sea plate boundaries were defined for the first time in
1970 by this Dr C Roman. However, with very few exceptions the plate
tectonic evolution models proposed in the last twenty years proved
unsatisfactory for the Black Sea, which fitted mostly on the 'outskirts'
of the model area, rather than at the centre of it : more specifically,
the plate tectonic models proposed to date dealt primarily either
with the Western Mediterranean , or with the Eastern Mediterranean,
or indeed, with the limit of the eastern Anatolian/Arabian plates
In all above cases, the dynamics of the Black Sea basin could NOT
be fully understood in an evolutionary sense, as the picture was
incomplete. Moreover certain areas such as the Black Sea`s Northern
Shelf, the Crimean peninsula, the Azov Sea and sometimes even the
Caspian Sea appear as rigid entities, unaffected dynamically by
the models proposed for the central part of the Black Sea basin
This paper makes the whole of the Black Sea offshore (and the adjacent
onshore) the focus of structural analysis of an area which stretches
from the Carpathians to the Caucasus and from the Southern Ukraine
and Sothwest Russia to the North Anatolian fault. A present-day
geodynamic model is proposed for the entire Black Sea, Azov Sea
and Marmara Sea
The model proposed has the double advantage, on one hand of explaining,
at a regional level, the relationship between the major rhegmatic
faults and structural units, such as the Eastern Carpathians vs.
the Mid Black Sea Ridge vs. the Shatzky Ridge vs. the Great Caucasus
and on the other hand, a second advantage is offering a framework
for correlating the regional dynamics to the local structure
in a coherent and orderly way.
This latter aspect should be of great advantage to the oil and gas
explorationists as particular examples of correlation between the
mega tectonics and the local hydrocarbon structures are considered
for Southern Ukraine, Southwest Russia and the Caucasus
A regional geodynamic conceptual cross-section is proposed for the
Black Sea and the present geodynamic model is made to illustrate
the evolution from the Cretaceous to the Present.
An analysis of the styles of hydrocarbon traps is presented, together
with a regional correlation of Stratigraphy.
