Experimental Stratigraphy

Geostatistical analysis of an experimental stratigraphy

[1] A high-resolution stratigraphic image of a flume-generated deposit was scaled up to sedimentary basin dimensions where a natural log hydraulic conductivity (ln(K)) was assigned to each pixel on the basis of gray scale and conductivity end-members. The synthetic ln(K) map has mean, variance, and frequency distributions that are comparable to a natural alluvial fan deposit. A geostatistical a...

Hierarchical Geostatistical Analysis of an Experimental Stratigraphy

A hierarchical geostatistical analysis is conducted on a high-resolution, multiscale hydraulic conductivity (lnK) map, created by scaling up an experimental stratigraphy. Unlike a previous study which evaluates lnK variograms within individual depositional environments, this study analyzes deposits (or samples) that incorporate multiple depositional environments. Based on conductivity cutoffs s...

Margin Morphodynamics: Debris Flows, Turbidity Currents and Experimental Margin Stratigraphy

Three approaches have been taken to the study of submarine debris flows. 1) Measurements laterally constrained debris flow dynamics and pore pressure variation have been performed in the “Fish Tank” facility. 2) The dynamics of unconfined debris flows have been studied using the “Main Channel.” 3) A numerical model of muddy debris flows is being extended to a) sandy debris flows and b) the rewo...

Sequence Stratigraphy

Sequence stratigraphy is the study of sediments and sedimentary rocks in terms of repetitively arranged facies and associated stratal geometry (Vail 1987; Van Wagoner et al 1988, 1990; Christie-Blick 1991). It is a technique that can be traced back to the work of Sloss et al (1949), Sloss (1950, 1963), and Wheeler (1958) on interregional unconformities of the North American craton, but it becam...
