Basin-Scale 3D Sedimentary Modelling: An Approach to Subdivide Baltic Sea Onshore Sediments for Land use and Construction

Abstract Understanding the local stratigraphy and geometry of sediment units is necessary for successful 3D modelling prediction ground behaviour engineering-geological properties urban land use construction. A detailed model main Rastaala basin in southern coastal Finland was constructed, combining a conceptual geological information from drill-hole logs geotechnical drilling. The based on cross-section approach, where were defined basis lithological boundaries that are major importance sequence events characterize late- postglacial evolution basin. present study combines allostratigraphy lithostratigraphy unconsolidated glacial, late-and Finland. It also investigates appearance distribution compares visualization results unit surfaces solids using two independent software packages. Finally, different provided so they can be applied to other onshore regions with similar settings Baltic Sea Basin.
