A Visual Basic program to plot sediment grain-size data on ternary diagrams
MetadataShow full item record
Sedimentologic datasets are typically large and compiled into tables or databases, but pure numerical information can be difficult to understand and interpret. Thus, scientists commonly use graphical representations to reduce complexities, recognize trends and patterns in the data, and develop hypotheses. Of the graphical techniques, one of the most common methods used by sedimentologists is to plot the basic gravel, sand, silt, and clay percentages on equilateral triangular diagrams. This means of presenting data is simple and facilitates rapid classification of sediments and comparison of samples.

A Visual Basic program to generate sediment grain-size statistics and to extrapolate particle distributions Poppe, Lawrence J.; Eliason, A. H.; Hastings, M. E. (Elsevier B.V., 2004-07-17)Measures that describe and summarize sediment grain-size distributions are important to geologists because of the large amount of information contained in textural data sets. Statistical methods are usually employed to ...
