Gradistat V 91 Link ((hot))

GRADISTAT Version 9.1, developed by Blott and Pye, is a widely utilized Microsoft Excel macro for rapid, automated grain size statistical analysis, including calculation of mean, sorting, skewness, and kurtosis. The tool offers high reliability for sedimentary data classification using both Folk and Ward (1957) and Method of Moments, producing graphical outputs directly within Excel.

How to Use GradiStat v.91 (Quick Tutorial)

Once you have the file, follow these steps:

1. Enable Macros: Open Excel and enable content (this is critical for the statistical engine).
2. Input Data: Paste your sieve data (Phi intervals or mm) into the "Input" sheet.
3. Select Method: Choose "Folk & Ward" or "Geometric" from the drop-down.
4. Run: Click the "GradiStat" button on the toolbar (or use the shortcut Ctrl+Shift+G).
5. Output: The results sheet instantly populates with Mean, Sorting, Skewness, and a full classification (e.g., "Slightly Gravelly Sandy Mud").

Key Features of v.91:

• Folk & Ward (1957) – Mean, sorting, skewness, kurtosis.
• Folk (1974) – Simplified graphic measures.
• McManus (1988) – Moment measures.
• Full Udden-Wentworth scale classification.
• Automatic ternary plotting (Sand-Silt-Clay).

Post: Why Gradistat v9.1 Remains the Gold Standard for Sediment Analysis

If you work in sedimentology, geomorphology, or environmental science, you have likely encountered Gradistat. With the release of version 9.1, the tool has solidified its place as the go-to solution for rapid, statistically robust grain size analysis.

For those searching for the "link," the challenge is often that it isn't hosted on a major corporate software repository. It is an academic tool, usually passed directly from the author or hosted on university departmental pages. GRADISTAT Version 9

Introduction: The Enduring Legacy of Gradistat

In the world of sedimentology and particle size analysis, few pieces of software have achieved the cult status of Gradistat. Developed by Simon J. Blott and Kenneth Pye of the UK-based company CCAP (Committee for the Coordination of Analytical Procedures), Gradistat provided a free, accessible, and scientifically rigorous method for calculating grain size statistics.

For nearly two decades, geologists, hydrologists, and soil scientists relied on this simple Microsoft Excel add-in to convert raw sieve and hydrometer data into the Folk and Ward (1957) graphic measures: Mean, Sorting, Skewness, and Kurtosis. Enable Macros: Open Excel and enable content (this

But as technology marched on, the original distribution channels disappeared. Today, the most searched phrase regarding this tool is "gradistat v 91 link" —a desperate plea for the final, stable version of a piece of software that has become increasingly difficult to find.
