Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and
gas fields and geothermal systems, and the extent and connectivity of the pore structure …

Enhanced understanding of subsurface water storage will improve prediction of future
impacts of climate change, including drought, forest mortality, wildland fire, and strained …

The critical zone (CZ), the dynamic living skin of the Earth, extends from the top of the
vegetative canopy through the soil and down to fresh bedrock and the bottom of the …

The production of natural gas has become increasingly important in the United States
because of the development of hydraulic fracturing techniques, which significantly increase …

Both vertical and lateral flows of rock and water occur within eroding hills. Specifically, when
considered over geological timeframes, rock advects vertically upward under hilltops in …

The rate of chemical weathering has been observed to increase with the rate of physical
erosion in published comparisons of many catchments, but the mechanisms that couple …

The transport of fluids through the Earth's crust controls the redistribution of elements to form
mineral and hydrocarbon deposits, the release and sequestration of greenhouse gases, and …

A negative feedback between silicate weathering rates and climate is hypothesized to play a
central role in moderating atmospheric CO 2 concentrations on geologic timescales …

Silicates constitute more than 90% of the rocks exposed in the Earth's land masses (Garrels
and Mackenzie, 1971). Most primary minerals comprising these rocks are …

Small angle neutron scattering (SANS) and scanning transmission electron microscopy
(STEM) were used to study film formation by magnesium alloys AZ31B (Mg-3Al-1Zn base) …
