- Abstract
- Integrated geohistory analysis performed on high-resolution stratigraphy ofVenezia1andLido1wells
(Quaternary^Pliocene interval) and low-resolution stratigraphy of a simulatedwell extending Lido 1
down to the base of Cenozoic (Palaeocene^Miocene interval) is used to reconstruct the interplay
between subsidence and sedimentation that occurred in theVenice area (eastern Po Plain) during the
last 60Myr, and to discuss the relationships between calculated subsidence rates and time resolution
of stratigraphic data. Both subsidence and sedimentation are mostly related to the tectonic evolution
of the belts that surround theVenice basin, in£uencing the lithosphere vertical motions and the input
of clastic sediments through time. In particular, two subsidence phases are recorded between 40^33.5
and 32.5^24Myr (0.13 and 0.14mmyear?1, respectively), coeval with tectonic phases in theDinaric
belt.Vice versa, during the main South-Alpine orogenic phase (middle^lateMiocene), quiescence or
little uplift (? 0.03mmyear?1) re£ects the location of theVenice area close to the peripheral bulge of
the South-Alpine foreland system. Early Pliocene evolution is characterised by a number of
subsidence/uplift events, among which two uplifts occurred between 5^4.5 and 3^2.2Myr (at ?0.4
and ?0.2mmyear?1, respectively) and can be correlated with tectonic motions in the Apennines.
During the last million years, theVenice areawas initially characterised by uplift (? 0.6mmyear?1
rising to ?1.5mmyear?1 between 0.4 and 0.38Myr), eventually replaced by subsidence at a rate
ranging between1.6 and1.0mmyear?1up to 0.12Myr and then decreased to 0.4mmyear?1, as an
average, up to present. Our results highlight that time resolution of the stratigraphic dataset deeply
in£uences the order of magnitude obtained for the calculated subsidence rate.This is because
subsidence seems to have worked through short-lived peaks (in the order of105 years), alternating with
long relatively quiescent intervals.This suggests caution when components of subsidence are
deduced by subtracting long-term to short-term subsidence rate. (literal)
