Reprocessing and interpretation of seismic reflection data at Messara Basin, Crete, Greece
Messara sedimentary basin located at Central Crete, Greece is covered by Quaternary and Neogene formations. Seismic reflection data along a 30 km W-E seismic line acquired by the Hellenic Petroleum Company (HPC) at Messara basin is reprocessed. The Kirchoff migrated data were subsequently spectrally balanced using a Ricker wavelet. The reprocessed seismic section provides an improved image of the shallow structures delineating a number of continuous reflectors in the upper Neogene formations. The maximum depth to the top of the preNeogene basement reaches 1000 m along seismic line Z1. Two structures are also imaged, the former consists of several thrust sheets and the latter is regarded as a positive flower structure. These reprocessed seismic data depict for the first time the subsurface structure of an extended area.
