A daisy chain method to quickly determine lithosphere, asthenosphere, and mantle properties from the loading history of an area

Summary The lithosphere and asthenosphere are fundamental to plate tectonics many other earth processes. Vertical motions can be measured quickly accurately by the satellite Global Positioning System, GPS, methods. This paper describes a new analytic method for inferring elastic viscous properties of upper mantle from uplift rate history an area that has been subjected past surface load changes. response time center loading is determined dimensions load, comprised linear segments, estimate flexural rigidity lithosphere, single constraint such as current central rate. then interpreted in terms depth profiles underlying mantle. described mathematically illustrated through analysis isostatic adjustment observed nine areas affected Little Ice Age glaciation. replicates published conclusions, extracts insights extensive literature, provides ways separate impacts on rates emergence, indicates widespread geographic distribution thin asthenosphere.
