Geological Objects and Structures in 3D: Observation, Interpretation and Building of 3D Models

About Adrien Frizon de LamotteDominique Frizon de LamottePascale LeturmyPauline Souloumiac

Dominique Frizon de Lamotte emeritus professor is the founder (in 1991) of the Department of Geosciences and Environment at the University of Cergy-Pontoise (now CY Cergy Paris Université). As a structural geologist his field of expertise is the sedimentary basins from their formation to their integration in mountain belts with a particular emphasis on the question of the tectonic/thermal inheritance. He handled different methodologies including geological mapping structural analysis and kinematic modelling of fold-thrust structures. This approach recently includes mechanical validation of kinematic models in collaboration with Pauline Souloumiac. His regional knowledge comprises the geology of North Africa the Arabian Plate and the Mediterranean area. Dominique is the author or coauthor of more than 150 papers in scientific journals and 2 continental tectonic maps (Africa and Arabia together with Pascale Leturmy). He considers that long distance correlations are useful tools to defend a global approach in geology.Pascale Leturmy is associated-professor at CY Cergy Paris Université since 1999 in the department of Geosciences and Environment. She is specialized in structural geology and worked on several fold-and-thrust belts like the front of Himalaya (PhD thesis in 1997) the subandean zone the Zagros or the North African belts. She uses several methodologies like field analysis mapping (the continental map of Arabia and surrounding areas published with Dominique Frizon de Lamotte) balanced cross section or numerical modeling to explore interactions between tectonic and sedimentation. More recently in collaboration with Pauline Souloumiac she involves mechanical analysis to explore fold-and-thrust belts evolution.Pauline Souloumiac is associated-professor at CY Cergy Paris Université since 2011 in the department of Geosciences and Environment. Her research field focus on the development of new methods of numerical simulations to treat the deformation of frictional sediments of the upper crust. In parallel she works out an analogue modelling laboratory dedicated to the validation of numerical simulations. The main objective of her research is to introduce mechanical concepts in the understanding of geological structures like fold-and-thrust belts or accretionary wedges. This methodology named tectono-mechanics is conducted in close collaboration with structural geologists like Pascale Leturmy and Dominique Frizon de Lamotte.Adrien Frizon de Lamotte is draughtsman at at CY Cergy Paris Université. After two years as student in an Architecture School in Paris he became metalworker in a family company. A serious health problem led him to a professional reorientation toward computer assisted conception and computer assisted ... draughtsmanship (CAC-CAD). Since 2018 he is in charge of CAC-CAD and 3D printing for the U-Maker project developing 3D models and prints for the pedagogy in Earth Sciences.
