Abstract
We have developed a simple model to evaluate the gravity gliding of nappes in sedimentary terranes. Three factors play a critical role in the model: 1) the ratio of horizontal to vertical stress; 2) the rate of fluid flow to the detachment horizon, and 3) the permeability of lithologies immediately above that horizon. Effective cap-rock permeabilities less than 10 -4 to 10 - 5 md are required for gravity gliding in a sedimentary basin. Based on available in situ permeability measurements, only shales and evaporites could have sufficiently low permeabilities on a regional scale. -Authors
