Abstract

This review explores the application of Forward Stratigraphic Modeling (FSM) in rift sedimentary basins, with a special focus on the capabilities of DionisosFlow™. Rift basins, shaped by complex tectono-sedimentary processes, present modeling challenges due to their evolving accommodation space, abrupt facies transitions, and variable sediment supply. DionisosFlow™, a diffusion-based FSM software, enables 3D simulation of sedimentary architecture by integrating tectonic and thermal subsidence, sediment transport, and sea-level change. Through a comparative evaluation of case studies, including the Midyan and East African Rift basins, this review highlights how DionisosFlow™ performs in both data-rich and data-scarce frontier basins. The tool's process-based modeling framework is compared with other FSM platforms like GPM and Badlands, emphasizing their respective strengths, limitations, and application scopes. Additionally, the review addresses methodological workflows, model calibration, and the integration of geological constraints, including plume-related magmatic influences. It concludes by outlining future directions for improving FSM realism in rift settings through enhanced data integration, multi-scale modeling, and scenario testing

裂谷沉积盆地的正演地层模拟

本文探讨了正演地层模拟（FSM）在裂谷沉积盆地中的应用，重点介绍了DionisosFlow™的功能。裂谷盆地是由复杂的构造沉积过程形成的，由于其不断变化的容纳空间、突变的相转变和多变的沉积物供应，给建模带来了挑战。DionisosFlow™是一款基于扩散的FSM软件，通过整合构造和热沉降、沉积物移动和海平面变化，可以实现沉积结构的3D模拟。通过对Midyan和东非裂谷盆地的案例研究进行对比评估，本综述突出了DionisosFlow™在数据丰富和数据稀缺的前沿盆地中的表现。该工具基于流程的建模框架与其他FSM平台（如GPM和Badlands）进行了比较，强调了它们各自的优势、局限性和适用范围。此外，该综述还讨论了方法工作流程、模型校准和地质约束的集成，包括与羽流相关的岩浆影响。最后，通过增强数据集成、多尺度建模和场景测试，概述了在裂谷环境中改进FSM真实感的未来方向
