This image shows the variation in permeability in a network of fractures due to quartz dissolving in the fractures. Each plane represents an individual fracture in the network. Fractures are the main ...

WEST LAFAYETTE, Ind. — Cracks are everywhere, and they often mean trouble. In the foundation of your house, in your windshield, in the tectonic plates below your feet. But, surprisingly, scientists ...

Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes ...

Fractures are the main way that water and other fluids move through rocks below the Earth's surface. As fluids move through these fractures, the fluids react with minerals in the rock and in the ...
