海洋水文地质
In 海洋地壳, fluid flow between the basaltic basement aquifer and the overlying ocean is an important control on heat transport, solute transport, and alteration 地壳的. As sediments gradually accumulate on 海洋地壳, they change the nature of fluid circulation within the basement aquifer. 我对海洋水文地质学的兴趣 include fluid and heat circulation patterns in 海洋地壳, 磁导率 evolution of 海洋地壳, and fluid and heat flow through seafloor sediments. 我研究过 fluid and heat flow in diverse settings, including the flanks of mid-ocean ridges, 俯冲带(e.g., Costa Rica, Nankai Trough, Cascadia, and southern Chile), 和河口.

As ocean crust subducts, fluid circulation within it is an important control on subduction 区温度. With current and former students, 我研究过 the evolution of hydrothermal circulation in subducting crust. In these studies, we examined some general aspects of fluid and heat circulation in subducting crust — for example, how far into a subduction zone can fluid circulation in the ocean crust aquifer persist, and what are the thermal consequences of that circulation? 我们已经研究了流体和热 circulation in the Nankai Trough (southern Japan), Cascadia, southern Chile, Mexico, 和日本北部的俯冲带. We found that the thermal effects of fluid circulation in subducting crust may extend the seismogenic portion of the plate boundary fault closer to the shoreline and populated areas than previously estimated.
I am also interested in how water derived from mineral dehydration reactions affects the fluid pressure distribution in subduction zones. 在近海的俯冲带 Costa Rica, I examined how the release of water bound in minerals may affect the distribution of fluid overpressures (and therefore effective stress) on the plate boundary fault. That study focused on dehydration reactions in sediment at fairly low temperatures (<150 ˚C). In ongoing projects, I am examining how the release of water from the basement rocks of oceanic crust at higher temperatures may affect the distribution of excess fluid pressures in 俯冲带, and how fluid sources from the subducting slab link with mantle wedge alteration and melting. This has implications for understanding the overall “plumbing system” of subduction zones.
断裂带渗透率
In collaboration with geologists and hydrogeologists in our department, I am working on a geological, geophysical, and hydrological study of field-scale fault-zone cementation 和磁导率. Geologic faults usually make the news only when they have produced 破坏性地震. However, faults also quietly have an important impact on society that most people never think about – they control the flow of groundwater and petroleum 在含水层和油田. In fact, a fault acting as a barrier for fluids can make the difference between a productive water or oil well and a terrible one. This is true for the Rio Grande aquifer system, in which groundwater levels can vary by hundreds 断裂带交叉时的脚. Through this study, we will address the difficult question of the role that natural cements plays in controlling the ease with which 流体穿过断层.
Below: Photo of a strongly-cemented portion of the Loma Blanca Fault.
The cements are composed of minerals precipitated from groundwater over thousands 年或以上. As the minerals precipitate they fill pores in the rock, clogging them, and making it difficult for fluids to flow. 然而，确定分布 断裂带的胶结是很困难的. As a result, fault-zone cementation is typically not accounted for in estimates of the impact of faults on fluid flow. 在我们的研究中， we are taking advantage of unique electrical properties of natural cements to map their 3-D distribution in an exceptionally well-exposed fault zone a few miles north 新墨西哥州索科罗市. Then, we will directly measure the impact of the cements on groundwater flow by drawing water from wells adjacent to the fault.

沉积学/sediment physical properties
Variations in sediment type and porosity can lead to large differences in sediment 磁导率. My previous sediment oriented studies range from determining sedimentation patterns on the northern California margin from reflection seismic data to laboratory consolidation 和磁导率 testing of sediments from San Francisco Bay, the Juan 德富卡山脊侧翼和刚果扇.
Some of my work in this area examines the thermal, diagenetic, and consolidation history of sediment approaching 南开海槽俯冲带 off Japan. 我检查过了 silica cementation of hemipelagic sediment on the Nankai margin. 我乘IODP号船航行 expedition to examine cementation/deformation of sediment approaching and entering 南开海槽俯冲带. I am also characterizing the thermal state of 南开海槽俯冲带.
