Maurice Lugeon FRS(For)^[1] HFRSE FGS (10 July 1870 – 23 October 1953) was a Swiss geologist, and the pioneer of nappe tectonics. He was a pupil of Eugène Renevier. Named for Maurice Lugeon, the lugeon is a measure of transmissivity in rocks, determined by pressurized injection of water through a bore hole driven through the rock. One Lugeon (Lu) is equivalent to one litre of water per minute, injected into 1 metre of borehole at an injection pressure of 10 atmospheres.
