SOME REMARKS ON THE BLACK SEA ROMANIAN SHELF GEOLOGICAL EVOLUTION AND RESULTS
(Abstract)
This paper contains some elements from "Integrated quantitative analysis
of Black Sea basin with special emphasis on Romanian shelf" published
in 1996 by the same authors.
Research is based on more than 350 seismic 2D time migrated lines (about 56
000 km), seiscrops from 3D surveys (about 800 km2) located on structures, gravity
and magnetic maps, 54 drillings and on lab-analyses.
Geological evolution of Romanian shelf and the whole Black Sea basin is followed
in the context of total subsidence with its two components: initial subsidence
fault controlled and post-extension, thermal and load subsidence. This evolution
is responsible for the structural ensemble arrangement and for each individual
feature.
The way in which geological evolution of the Romanian shelf had influenced
hydrocarbon generation and migration, formation of traps, as well as prospective
accumulation in structural and/or lithostratigraphic traps are also considered.
Key words: Extension, normal-listric fault systems, initial subsidence, thermal
subsidence, load subsidence, compression, plunged structures, litho-stratigraphic
traps.
