摘要：

The scale invariant nature of crustal heterogeneity has been established through direct measurements of rock properties and inferences from geophysical observations. We examine the behavior of crustal density variations over length scales from centimeters to hundreds of kilometers using well-logs, surface rock samples and observed gravity data. The three data types support a simple model of an isotropic, scaling crust with density characterized by a power-law spectral behavior.
