Computer modeling the internal architecture of carbonate platforms
- Univ. of London (England)
A numerical computer model is described that calculates the internal architecture of carbonate platforms in response to varying values of carbonate production, subaerial and submarine erosion, sediment redeposition, and sea-level changes. The computer-generated sections closely resemble large-scale outcrops and interpreted seismic profiles through carbonate platforms. Stillstand and transgressive sequences have prograding and downlapping platform geometries with lagoons developing in transgressive systems. Regressive sequences have downlapping clinoforms and erosional upper surfaces. Glacioeustatic scale cycles have a major control on platform geometry with erosional sequence boundaries developing during low stands and platform drowning occurring during transgressive periods. Lowstand downlapping wedges are minor features when compared with clastic systems, and major progradation and downlap of slope deposits develop with transgressions and flooding of platform tops.
