is a premier, macro-enabled Microsoft Excel spreadsheet program widely utilized by geologists, geomorphologists, and environmental scientists for calculating sediment grain size statistics. Originally developed by Simon J. Blott and Kenneth Pye, the program automates the complex mathematical equations required to analyze unconsolidated sediments gathered via sieve or laser granulometry methods. Because GRADISTAT is open-source and freely distributed, it serves as an indispensable tool for academic researchers and industry professionals alike. Key Capabilities of GRADISTAT v9.1
If you work in sedimentology or a related earth science field, you know that analyzing grain size distributions is fundamental to understanding sedimentary environments. However, when dealing with hundreds of samples, the manual calculation of statistics can be a laborious, error-prone process. Since its inception, a computer program called has been the go-to solution for researchers worldwide, providing a rapid, accurate, and free method for grain size analysis.
