GRADISTAT processes physical raw weight values gathered from dry sieving, or percentage frequencies outputted from advanced laser granulometers, X-ray sedigraphs, and Coulter counters. It completes a massive list of math calculations automatically, reducing the calculation time to an estimated 50 samples per hour.

Automatically provides sediment descriptions (e.g., "Fine Sand," "Sandy Gravel") based on the Udden-Wentworth scale.

Compares results from different statistical methods (e.g., inclusive graphical vs. moment) within the same interface.

Processing data in the free v9.1 workbook involves a structured, sequential workflow: (PDF) GRADISTATv8 - ResearchGate
