Research redefines the properties of faults when rock melts

Magnified through a microscope, diatoms, which are a type of siliceous microalgae preserved within sediment, helped the researchers determine the salinity levels of the core samples. Photo courtesy of Jessica DePaolis.

The modern Seattle fault zone cuts directly through the densely populated Puget lowlands, including Seattle and its metro area. Fifty million years ago, the continent tore in two here, setting the geologic stage for the modern faults, according to a new Tectonics study. Credit: Washington Geological Survey.
