Maurice Lugeon (July 10, 1870 - October 23, 1953) was a Swiss geologist, pioneer of nappe tectonics. He was a pupil of Eugène Renevier. Unit of transmissivity in rocks is named after Maurice Lugeon. 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 equal to one litre of water per minute injected into 1 meter of borehole at an injection pressure of 10 atmospheres.
