P603 3D GEOMETRY OF POLYGONAL FAULT PATTERNS FORMED BY MULTIDIRECTIONAL GRAVITATIONAL GLIDING IN ANALOGUE EXPERIMENTS P. VICTOR and I. MORETTI Abstract 1 Analogue experiments have been carried out to understand the deformation of the sandy channel traps in a shale prone sedimentary pile on passive margins where 3D gravitational gliding is active such as the Congo-Zaire delta. Results show that the channel will be boudinaged and therefore dismembered during the flow of the ductile material. Faults in the channel interior form always perpendicular to its borders and are not influenced by the regional slope. On the other hand the presence
