From palinspastic reconstructions to kinematic basin models

Abstract
We address the need for kinematic geological models to examine and communicate changes in sediment basin to reservoir seale geomelry with time. A prototype tool for the calculation and visualization of such models is presented, aimed at studying subsidence rates and patterns at basin scale. A backstripping algorithm is applied to a 3D basin model consisting of prismatic volumes, constructed from an initial set of stacked triangulated surfaces. As a result, we obtain a collection of palinspastically restored volumes for each timestep of basin evolution. The backstripped volumes of each layer are then arranged within a timescene, and the timescenes set up to form an hierarchical timetree. By interpolating between succeeding key-frames 1 the subsidence history of the basin can be viewed as an interactive animation. While the visualization component provides a general way to animate geological models 1 Lhe backstrippiug part of the modeling Looi represents a simplified solution that imposes a few limitations. Finally we give sorne implementation detaiis and provide an example to ill ustrate the approach.
