Toggle between the traditional Folk and Ward (1957) graphical method or the Method of Moments . Folk and Ward is generally preferred for geological sediment analysis. Step 4: Run the Analysis
Grain size analysis is a foundational method in geology, sedimentology, and geography. It helps researchers understand sediment transport, depositional environments, and soil mechanics. While laboratory methods like sieving or laser diffraction provide raw data, converting that data into meaningful statistics requires specialized software.
