Analysis of the shape of sedimentary particles can provide information about their transport history and aid facies differentiation and the characterization of depositional environments. Triangular (Sneed and Folk) diagrams, employing ratios of the three orthogonal particle axes, have been advocated as the most appropriate method for unbiased presentation of primary particle shape data. A spreadsheet method for the production of these diagrams is described. Clast data-sets from a range of…

New statistical methods for the comparison and characterization of particle shape

Novel methods for robust statistical testing of particle shape data based on a transform that permits multivariate statistical methods for the analysis of compositional data to be extended to shape are presented.

Grain-Shape Analysis—A New Method for Determining Representative Particle Shapes for Populations of Natural Grains

Abstract The size sorting and shape sorting of gravel bedload by running water often is investigated using identifiable tracer grains that represent the grains within the riverbed. A new, robust, and

Pebbles, Shapes, and Equilibria

The shape of sedimentary particles may carry important information on their history. Current approaches to shape classification (e.g. the Zingg or the Sneed and Folk system) rely on shape indices

Shape and erosion of pebbles.

It is found that the curvature distribution allows finer discrimination than traditional measures of aspect ratios and connects to the microscopic action of erosion processes that are typically faster at protruding regions of high curvature.


Abstract: The shape of granular particle from a filter layer represent a determinant factor regarding the efficiency of filtration process. In order to adequately predict the efficiency of granular

Correspondence Analysis in Ternary Diagrams - A Graphical Approach to Improving the Validity of the Interpretation of Point Clouds

Ternary diagrams are proposed as an approach to achieving a valid representation and interpretation of three-dimensional point clouds when plotted two-dimensionally and do not necessarily meet the mathematical prerequisites for CA coordinates.

Short title: algebra algorithms for automated generation of grain-size maps

The grain-size distribution of sediments is a fundamental characteristic in understanding the earth’s surface environments and an essential tool in classifying sedimentary environments. Grain-size



The description and representation of particle shape

Despite widespread agreement on the value of shape analysis in the study of sediments, methods of representing and summarizing data have proved difficult to standardize. This paper shows that Sneed

Fabric Shape and the Interpretation of Sedimentary Fabric Data

ABSTRACT The concept of fabric shape provides a powerful means of visualizing and analyzing data on sedimentary fabric. The shape of a fabric is defined in terms of the ratios between eigenvalues S1

Grain-shaped indices and isometric graphs

ABSTRACT Plotting of grain-shape data on a conventional ternary composition diagram, with long (L), intermediate (I), and short (S) axes of clasts as end members, has advantages over triangular

Fabric characteristics of subaerial slope deposits

The clast fabrics of certain types of terrestrial slope deposits are reviewed and compared, including the deposits of rockfalls, solifluction, debris flows, dry grain flows, frost‐coated clast flows

Aggregate clast form characteristics of deposits near the margins of four glaciers in the Jotunheimen Massif, Norway

The form of a clast is defined by the relative dimensions of its three principal axes. Samples of clasts from deposits with different erosional ‘histories’ near the margins of four Jotunheimen

Pebble shape (and size

ABSTRACT The mathematical technique of R-mode factor analysis was applied to the long, intermediate and short axes of one synthetic random data set and three sets of natural pebbles to extract the

Modification of clast shape in high-Arctic glacial environments

ABSTRACT Clast shape data from a range of different glacial environments at several high-arctic valley glaciers in Svalbard are presented. These data add to the growing body of reference information

An evaluation of shape indices as palaeoenvironmental indicators using quartzite and metavolcanic clasts in Upper Cretaceous to Palaeogene beach, river and submarine fan conglomerates

The feasibility of using quantitative shape measurements to discriminate between clast populations from different depositional settings was evaluated using samples from 11 fluvial, six submarine fan

Pebbles in the Lower Colorado River, Texas a Study in Particle Morphogenesis

The Colorado River in its course from central Texas to the Gulf of Mexico carries quartz, chert, and limestone pebbles which can be traced for distances of up to 270 miles from their source.
