Influence of a thin veneer of low-hydraulic-conductivity sediment on modelled exchange between river water and groundwater in response to induced infiltration
Donald O. Rosenberry, Richard W. Healy
2012, Hydrological Processes (26) 544-557
A thin layer of fine‐grained sediment commonly is deposited at the sediment–water interface of streams and rivers during low‐flow conditions, and may hinder exchange at the sediment–water interface similar to that observed at many riverbank‐filtration (RBF) sites. Results from a numerical groundwater‐flow model indicate that a low‐permeability veneer reduces the...

K.M. Farrell, W.B. Harris, D. J. Mallinson, S.J. Culver, S.R. Riggs, J. Pierson, Self-Trail J.M., J.C. Lautier
2012, Journal of Sedimentary Research (82) 364-378
Proposed here is a universally applicable, texturally based classification of clastic sediment that is independent from composition, cementation, and geologic environment, is closely allied to process sedimentology, and applies to all compartments in the source-to-sink system. The classification is contingent on defining the term "clastic" so that it is independent...

Effects of smectite to illite transformation on the frictional strength and sliding stability of intact marine mudstones
Demian M. Saffer, David A. Lockner, Alex McKiernan
2012, Geophysical Research Letters (39)
At subduction zones, earthquake nucleation and coseismic slip occur only within a limited depth range, known as the “seismogenic zone”. One leading hypothesis for the upper aseismic-seismic transition is that transformation of smectite to illite at ∼100–150°C triggers a change from rate-strengthening frictional behavior that allows only stable sliding, to...
