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 ...

For many decades the rock mechanics community has been tacitly assumed that a rock mass can be equated to the sum of fractures and intact rocks. Accordingly, the behaviour of a rock mass can be ...

Local planetary geologist Chris Okubo is on a mission to understand the past roles of groundwater and faulting on Mars by studying similar locations on Earth. Okubo works in the Astrogeology Research ...

Newberry Volcano in central Oregon contains ideal conditions for a superhot rock enhanced geothermal system candidate. An ...

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 ...
