The airy and pratt isostasy
WebSep 9, 2024 · The isostatic models illustrated in Fig. 1 imply different gravity anomalies and crust and mantle structures. Airy and Pratt, for example, predict that free-air gravity anomalies will generally be small over volcanoes because they are underlain by either a thick, uniform-density, crustal “root” or a constant thickness low-density crust, the … WebJan 22, 2024 · The Airy (left) and Pratt models for local isostasy.
