Particle size analysis is a cornerstone of sedimentology, engineering, and environmental science. Since its inception, GRADISTAT has remained the gold standard for researchers seeking to transform raw sieve or laser diffraction data into meaningful statistical insights. With the release of Version 9.1, the software continues to streamline the calculation of grain size statistics using the most recognized methodologies in the field. What is GRADISTAT v9.1?

Due to compatibility challenges with newer versions of Excel, some researchers utilize the

Enter your grain size data (sieve weights or laser percentage data) into the provided input template.

The program is highly valued for its ability to process approximately 50 samples per hour and provide both tabular and graphical outputs. Michigan Technological University GRADISTAT software - Kenneth Pye Associates Ltd gradistat v 91 link

The standard public versions are usually labeled v8 or v9. If you have a file specifically labeled "v 91," it is likely a specific university modification or a typo for v9.1. Always scan downloaded Excel macros with antivirus software before enabling macros.

Open the GRADISTAT file and navigate to the data entry sheet. Input your sieve mesh sizes or laser size boundaries in the designated columns.

You must navigate to Excel’s Trust Center and select "Enable all macros" (or choose to trust the specific document) for the program to function. Without macros enabled, the buttons and automated calculation sheets will not work. Step-by-Step Guide to Using Gradistat v 9.1 Particle size analysis is a cornerstone of sedimentology,

The core purpose of is to bypass hours of manual calculator work by establishing an automated data pipeline. Geologists rely on specific mathematical descriptors to characterize a sample's depositional environment, historical transport medium, and environmental energy levels.

: Supports results in both metric (micrometers/millimeters) and logarithmic (phi) units. Graphical Outputs

Instead of inputting your data into complex external software, GRADISTAT operates as a macro-enabled Excel workbook. It organizes data for easy viewing, performs rapid calculations using multiple statistical methods, and even generates graphical outputs like frequency curves and ternary plots to help you classify sediments based on gravel, sand, and mud ratios.

Open the workbook and make sure your Excel configuration has . Navigate to the Single Sample Data Input sheet. Input your physical sieve aperture sizes or laser granulometer bin ranges in Column B.

Navigate to the workbook tab named (or Multi-Sample equivalent depending on batch scope).
