| الوصف: |
The profile 9N was recorded in 1988 as part of the DEKORP project, the German deep seismic reflection program. The focus of the DEKORP project was on deep crustal and lithospheric structures and therefore originally not on structures at lower depths. From today's perspective, however, this depth range is of great interest for a wide range of possible technical applications (including medium-depth and deep geothermal projects). The original data is published by Stiller et al. (2019). The profile 9N was reprocessed on behalf of the Hessian Agency of Nature Conservation, Environment and Geology (HLNUG). The focus of the reprocessing was on improving the resolution / mapping of geological structures down to a depth of 6 km (approx. 3 s TWT) to describe the prolongation of faults and geological structures in more detail than in previous studies. In order to achieve these goals and in view of the fact that today's processing and evaluation methods have improved considerably compared to the 1990‘s, a state-of-the-art reprocessing was implemented. In comparison with the original processing (Stiller et al. (2019), more sophisticated processing steps like CRS (Common Reflection Surface) instead of CDP (Common Depth Point) stacking, turning-ray tomography and prestack time and depth migration were carried out. The reprocessed DEKORP-9N survey comprises all datasets newly achieved in addition to the datasets from the original processing (Stiller et al. (2019)), i.e. (1) as unstacked data the raw data, the CRS processed data and the migrated image gathers, and (2) as stacked data the pure CRS stack, the poststack-time as well as prestack-time and prestack-depth migrated sections. Moreover, (3) all velocity models used for the different versions including (4) the separate first-break tomography inversion as well as (5) several attribute analyses (RMS amplitude, instantaneous frequency and phase, Q-factor and others) are contained. All reprocessed data come in SEGY trace format, the final sections additionally in ... |
