It can process large datasets of particle size distributions in a short time.
The software operates within Microsoft Excel, utilizing Visual Basic to calculate parameters using both the Folk and Ward (1957) and moments methods. It is capable of processing data for a wide range of unconsolidated sediments. GRADISTAT v9.1 vs. Previous Versions
Some users have ported or backed up the original Excel files onto platforms like GitHub to ensure long-term availability.
Enter your grain size data (sieve weights or laser percentage data) into the provided input template.

is a specialized, Excel-based grain size distribution and statistics software package widely utilized by geologists, physical geographers, and environmental scientists to automate the analysis of unconsolidated sediments. Initially developed by Simon Blott and published alongside Kenneth Pye in 2001, this tool transforms raw lab data from sieving and laser granulometry into standardized geological metrics.
GRADISTAT processes mass or percentage data retained within specific size intervals. It bypasses manual, error-prone graphical calculations by computing foundational sedimentological metrics instantly:
The program automates sedimentological mathematics, converting raw weights from sieve analysis or laser granulometry into standardized physical and statistical descriptions. Understanding the GRADISTAT Architecture
Dr. Simon Blott and various sedimentology research groups frequently maintain project pages on ResearchGate where the original .xls or .xlsm files are uploaded as supplementary resources to their foundational papers.
Why hunt for a gradistat v 91 link when software like GRADISTAT Pro , G2S , or SedTools exists?
GRADISTAT is a widely used Microsoft Excel-based program for grain size analysis and statistical calculations in sedimentology and geomorphology.
Is it legal to use the gradistat v 91 link? Since v 9.1 was released as (not trialware), the original license permitted free distribution for academic and non-commercial purposes. However, because CCAP no longer supports it, using v 9.1 is generally considered "legacy use." You cannot use Gradistat v 9.1 for commercial consulting without purchasing the Pro version.
