Hydrogeologic Studies of Heat and Mass Transport

Image of Current Focus for Hydrogeologic Studies of Heat and Mass Transport

Our project focuses on hydrothermal systems in volcanic terranes.  Heat flow, multiphase ground-water flow, and deformation are tightly coupled in volcanically active areas.  Changes in the hydrothermal system can signal intrusive events and otherwise reveal some of the physical processes surrounding volcanic unrest.  This project gathers and interprets hydrologic data and helps to develop and maintain leading-edge hydrologic-modeling tools to enhance understanding of volcanic hydrothermal systems.  These tools are applied to a wide variety of volcanic systems, including several in the western United States.

 

Specific research questions include (1) What are the modes of heat and mass transport from magma to the shallow subsurface?  (2) What are the pressure, temperature, and fluid-saturation conditions between magma and the land surface?  (3) What controls the permeability of volcanoes?  How does it vary in space and time?  What role do temporal variations in permeability play in the evolution of volcanogenic hydrothermal systems?  (4) How well-coupled are various fluid flow, transport, and mechanical deformation processes?  (5) How can we evaluate hydrothermal systems in volcanoes dominated near the surface by cold ground-water recharge?  (6) What is the interplay between groundwater transients, seismicity, and volcanic activity at various timescales?

 

Permeability of the continental crust.   Permeability is a parameter that is widely measured in the uppermost few kilometers of the Earth’s crust, but direct measurement is infeasible deeper in the crust.  As an alternative to direct measurement, we used (i) models of heat and mass transport and (ii) the progress of metamorphic reactions driven by fluid flow to arrive at a coherent permeability-depth curve for the tectonically active portions of the continental crust, log k =  -14-3.2 log z, where permeability k is in meters squared and depth z is in km (Reviews of Geophysics, 1999).  This k-z relation implies (i) that typical metamorphic fluid-flux values of ~10-11 m/s are consistent with fluid pressures significantly above hydrostatic values; (ii) that metamorphic fluid flux from large orogens may be sufficient to cause significant climatic effects if retrograde carbonation reactions are minimal; and (iii) that there is a significant capacity for diffuse Earth degassing in tectonically active regions (Geology, 1999).  Our inference of a large capacity for water upflow through tectonically active continental crust is relevant to competing models for the evolution of the hydrosphere over geologic time.  W.W. Rubey (1951) examined various hypotheses regarding the origin of sea water and concluded that the most likely was volcanic outgassing, a view accepted by most Earth scientists for the next several decades.  More recent work suggests that the rate of subduction of water is much larger than the volcanic outgassing rate, lending support to alternative hypotheses, such as continuous replenishment of water by cometary impacts.  The potential for escape of recycled water, or slow, diffuse outgassing of primordial water, eliminates the mass-balance argument against the Rubey hypothesis (Proceedings of the National Academy of Sciences, 2002).  More recently, we have attempted to explain the apparent coherence of mean permeability in the continental crust (and permeability-depth relations) on a very large scale.  We have suggested that large-scale crustal permeability adjusts to accommodate rates of internal and external forcing.  We use first-order calculations and numerical modeling to explore the hypothesis that upper-crustal permeability is influenced by the magnitude of external (meteoric) fluid sources, much as lower-crustal permeability is influenced by the magnitude of internal (magmatic, metamorphic) fluid sources (Geofluids, 2008).  Finally, most recently, we have extended these results by surveying recent observations of high permeabilities associated with shorter time and length scales, and by considering permeability decay (Geofluids, 2010).

 

Cascade Range heat flow.  Hydrothermal heat discharge in the Cascade Range includes the heat discharged by thermal springs, by “slightly thermal” springs that are only a few degrees warmer than ambient temperature, and by fumaroles.  Thermal-spring heat discharge is calculated on the basis of chloride-flux measurements and geothermometer temperatures and totals ~240 MW in the U.S. part of the Cascade Range, excluding the transient post-1980 discharge at Mount St. Helens (~80 MW as of 2004-5).  Heat discharge from “slightly thermal” springs is based on the degree of geothermal warming (after correction for gravitational potential energy effects) and totals ~660 MW.  Fumarolic heat discharge is calculated by a variety of indirect and direct methods and totals ~160 MW, excluding the transient mid-1970s discharge at Mount Baker (~80 MW) and transient post-1980 discharge at Mount St. Helens (>230 MW as of 2005).  Other than the pronounced transients at Mount St. Helens and Mount Baker, hydrothermal heat discharge in the Cascade Range appears to be fairly steady over a ~25-year period of measurement.  Of the total of ~1,050 MW of “steady” hydrothermal heat discharge identified in the U.S. part of the Cascade Range, less than 50 MW occurs north of latitude 45o15’ N (~0.1 MW per km arc length from 45o15’ to 49oN).  Much greater rates of hydrothermal heat discharge south of 45o15’N (~1.8 MW per km arc length from 40 to 45o15’N) may reflect the influence of Basin and Range-style extensional tectonics (faulting) that impinges on the Cascades as far north as Mount Jefferson but is not evident farther north.
