Originally developed by Simon J. Blott and Kenneth Pye, GRADISTAT was designed to automate the calculation of grain size statistics from standard measurement techniques, such as dry/wet sieving and laser granulometry. The program was introduced to the scientific community via a seminal paper in Earth Surface Processes and Landforms in 2001, and has since become a benchmark tool in sedimentary geology.
Given the lack of an official download link for v9.1, here are the best paths to acquire the software:

The program produces a suite of critical sedimentological metrics: GRADISTAT software - Kenneth Pye Associates Ltd Originally
Gradistat V 9.1 has a wide range of applications across various industries, including:
You can find the standard spreadsheet versions and official technical documentation via the Kenneth Pye Associates Ltd GRADISTAT Software Page . For researchers tracking collaborative datasets or looking for modified R-package adaptations based on the tool's core logic, you can explore the G2Sd CRAN Repository . Core Statistical Methodologies
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.
GRADISTAT is a standard tool in paleoenvironmental reconstruction and coastal studies. Recent research (as of 2024) has utilized v9.1 for documenting lithological changes in Greenland core sediments and comparing laboratory-based particle size analysis techniques.
