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 ...

All rocks in the earth's crust are fractured to some extent. Fractures form in response to stress. The origin of stress can be lithostatic (arising from the weight of the earth's crust), high fluid ...

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 ...

The heterogeneity and complexity of flow paths in fractured rocks make field studies very difficult. As a result, there are relatively few field study sites where the distribution and character of ...
