Gradistat V 91 Link High Quality Jun 2026

is an industry-standard, Microsoft Excel-based software application specifically designed for calculating particle size statistics from sieve or laser granulometer data. Originally developed by Simon Blott and published alongside professor Kenneth Pye, the utility bridges the gap between raw experimental mass fractions and complex, publication-ready sedimentological metrics. If you are looking for a reliable way to access and apply this package, understanding how it operates within the context of geological research is essential.

: Automatically outputs descriptive naming terminology based on physical sediment compositions (such as "very well sorted, fine sand"). gradistat v 91 link

Researchers rarely analyze a single sample. GRADISTAT v 9.1 allows users to input dozens of samples simultaneously. With a click of a button, it generates: Individual and summary sample reports. Frequency distribution histograms. With a click of a button, it generates:

Once macros are enabled, you can start using the software. The workbook contains several worksheets, including the main interface for data input and a separate sheet with detailed instructions and examples. You will typically paste your grain size data (particle size classes and corresponding percentages) into the "Single Sample Statistics" or "Multiple Sample Statistics" input area, and then click the appropriate button to generate results. It automatically solves for Sample Mean

It automatically solves for Sample Mean, Mode(s), Standard Deviation (Sorting), Skewness, and Kurtosis. Percentile Data: It extracts critical d-values including D10cap D sub 10 D50cap D sub 50 (median), and D90cap D sub 90 used widely in engineering and engineering geology.
