Processes data from modern laser diffraction machines.

Developed originally by Simon Blott, Gradistat was created to automate the tedious calculations involved in sedimentology. It functions as an Add-In for Microsoft Excel, making it highly accessible for students and professionals alike. The program accepts data from various methods, including: Sieve analysis Laser diffraction (such as Malvern or Beckman Coulter) Pipette and hydrometer methods Key Features and Capabilities gradistat v 91 free

Version 9.1 carries forward the core analytical capabilities, including:

Gradistat V 9.1 is a sophisticated statistical software package designed to facilitate data analysis, visualization, and interpretation. It offers a wide range of statistical tests, regression analysis, and data manipulation tools, making it an indispensable resource for anyone working with data. The software is particularly popular among researchers, academics, and students due to its user-friendly interface, flexibility, and accuracy.

Your grain size data should be prepared in a spreadsheet. You will need columns for the grain size class (e.g., aperture in microns or phi intervals) and the corresponding weight or percentage of sediment retained in that class. Instant calculation of grain size parameters

GradiStat v9.1 remains a cornerstone of sedimentological research, a testament to its thoughtful design and enduring utility. Its ability to quickly, accurately, and freely process grain size data has made it an indispensable tool in labs and universities worldwide. While its age presents minor compatibility challenges, its core functionality is as relevant today as it was when first published.

Since Gradistat runs on VBA, you must "Enable Content" when opening the file in Excel.

Fortunately, remains one of the most reliable and widely used tools for calculating grain size distribution. Originally developed by Simon Blott and Kenneth Pye, GRADISTAT is a free Microsoft Excel-based macro program that dramatically speeds up workflows, processing up to 50 samples per hour. It functions as an Add-In for Microsoft Excel,

Descriptive terms based on the Folk and Ward scale (e.g., "Very Fine Sand").

GradiStat is a grain size distribution and statistics package specifically designed for the analysis of unconsolidated sediments. It was developed by Simon J. Blott and Kenneth Pye and was officially published in the journal Earth Surface Processes and Landforms in 2001.
