从北方亚平宁山脉中新世Marnoso-arenacea组的古水流、总成分、岩石碎屑和重矿物数据可以推断出六个物源区。五个主要是盆外（阿尔卑斯山I和II;亚平宁I，II和III），一个是盆内。识别的特点multicomponent材料加强了这样的想法，迁移的前渊内的板块构造框架发生在亚平宁山脉。在Marnosoarenacea沉积体系的研究中，岩相、古水流和沉积相分析数据的整合已被证明是理解深海扇体系复杂性的一种非常有效的方法。
ABSTRACT Paleocurrent, gross composition, rock-fragment data, and heavy mineral data from the Miocene Marnoso-arenacea Formation of the Northern Apennines suggest six source areas. Five are primarily extrabasinal (Alpine I and II; Apenninic I, II, and III) and one is intrabasinal. The identification of characteristic multicycle materials reinforces the idea that migration of foredeeps within a plate-tectonic framework occurred in the Apennines. Integration of petrofacies, paleocurrent, and sedimentary-facies-analysis data in the study of the Marnosoarenacea depositional system has proved a very powerful method for understanding the complexity of a deep-sea fan system.
