Density Anomalies and Geophysics – Concepts and Methods

ERT transect with karst

In general, the density of the earth increases with depth, from a lighter silicic crust (or basalt in the oceans) to a sequence of denser, more metallic rocks from the mantle to the inner core. This is what we expect when digging or drilling into the earth. But occasionally we are surprised by the … [Read more...]
