Originally developed by geoscientists Simon J. Blott and Kenneth Pye, this macro-enabled spreadsheet automates the laborious mathematical equations required to analyze unconsolidated sediments.
A standout feature of GRADISTAT is its ability to calculate statistical parameters using multiple methods simultaneously, allowing for robust comparison of compositionally variable sediments.
You must enable macros in Microsoft Excel for GRADISTAT to function properly.

Enable Macros: Since GRADISTAT runs on Excel VBA, you must "Enable Content" or "Enable Macros" when opening the file. Input: Paste your data into the designated "Input" sheet.
If you are a sedimentologist, geologist, or environmental scientist, you are likely familiar with the challenge of processing large datasets to classify sedimentary environments. The calculation of fundamental parameters like mean grain size, sorting, skewness, and kurtosis for hundreds of samples can be a laborious and highly time-consuming process.
