Title: Burial and Thermal Geohistory Analysis at Passive Continental Margins: ABSTRACT

Author(s): David Falvey, Brett Edwards, Ian Derglton

Article Type: Meeting abstract


Burial geohistory analysis involves progressive stripping of sediment bodies defined by well chronostratigraphic horizons. Underlying section, to basement, is corrected for compaction effects and paleo-water-depth, and plotted as a "paleowell" section in a time-depth framework. The procedure is amenable to computer processing.

Given a tectonic model for basin subsidence, a theoretical paleobent flow function can be applied to the calculation of integrated thermal and maturation history of the well section as a function time and depth. The procedure may be extended to cross sections providing migration direction relative to trap formation. Our examples, from the southern and southwestern margins of Australia, illustrate these applications, and provide constraints to passive margin formation processes.
