Gradistat V 91 Free !!hot!! -

GRADISTAT is a widely used, free software package for grain size analysis, specifically designed to process data from sieve or laser granulometer analyses to determine statistical parameters of unconsolidated sediments . Developed by Simon Blott and Kenneth Pye

For sedimentologists, geologists, and environmental scientists, accurately analyzing sediment grain size is crucial. One of the most enduring, versatile, and widely used tools in this field is . Originally developed by Simon Blott and Kenneth Pye, this software simplifies the complex calculations required to interpret particle size distributions from sieving or laser diffraction data.

As an Excel macro, it works in a familiar environment. Input your data, click "Run," and receive instant results. 3. Comprehensive Output The software produces detailed reports, including: Percentage of gravel, sand, and mud. Median and mean values.

: It calculates statistics using arithmetic and geometric methods (in metric units) and logarithmically (in phi units). It employs both the Method of Moments and the Folk and Ward (1957) graphical method , allowing researchers to compare results from different approaches. gradistat v 91 free

: When you open the extracted Excel file, you will likely see a security warning at the top of the screen because the program uses Visual Basic macros.

is a powerful, free resource that has made complex grain size analysis accessible to researchers worldwide. By automating the calculation of key sedimentological parameters, it saves time and reduces the potential for manual errors. While later versions exist, v9.1 remains a trusted standard, cited in numerous scientific publications.

GRADISTAT automates the calculation of essential sedimentological statistics, allowing researchers to process approximately . GRADISTAT is a widely used, free software package

Enter sample names and raw data (weight or percentage) into the spreadsheet.

Best for sharing the news quickly with a community of researchers.

⭐⭐⭐☆☆ (3/5) – Essential for specific niche tasks, frustrating for modern users. Originally developed by Simon Blott and Kenneth Pye,

: It supports both the Method of Moments (arithmetic and geometric) and the Folk and Ward (1957) graphical methods.

This is the most popular method in GradiStat. Instead of using every single data point, it uses four specific percentiles (5%, 16%, 84%, and 95%) from the cumulative grain size curve to calculate statistical parameters. This method is less sensitive to extreme values ("outliers") in the tails of the distribution than the Method of Moments. Research comparing these methods has suggested that Folk and Ward measures, when expressed in metric units, often provide the most robust basis for routine comparisons of compositionally variable sediments.
