Quantitative tools for seismic stratigraphy and lithology characterization
Seismological images represent maps of the earth’s structure. Apparent bandwidth limitation of seismic data prevents successful estimation of transition sharpness by the multiscale wavelet transform. We discuss the application of two recently developed techniques for (non-linear) singularity analysis designed for bandwidth limited data, such as imaged seismic reflectivity. The first method is a...
متن کاملQuantitative Snow Stratigraphy and Stability Derived from High-resolution Penetrometry
Precise measurements of snow structural parameters and stratigraphy are essential to understand and model snow physical processes, in particular with respect to avalanche formation. However, most snow measurements are limited in spatial resolution and by extensive measurement times, and therefore lack practicability for avalanche professionals. The snow micro-penetrometer (SMP), a portable, hig...
متن کاملFractional Spline Matching Pursuit: a quantitative tool for seismic stratigraphy
A matching pursuit algorithm is used to obtain quantitative information on the litho-stratigraphical content of seismic data. The method is based on a greedy non-linear algorithm decomposing the data into atoms drawn from a redundant dictionary defined by fractional splines. The atom’s parametrization provides localized scale, order and direction attributes which carry information on the strati...
متن کاملStratigraphy and Relative Geochronology
Stratigraphy is the science that studies the strata, or beds, of (mainly) sedimentary rocks in order to extract from them the history of the earth’s surface. By grouping the bed successions in stratigraphic units and by studying their geometrical relationships with some simple rules, it creates the fundamental temporal relative framework necessary to understand the origin of the rock units them...
متن کاملSequence 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...
