GRADISTAT is a standard tool in paleoenvironmental reconstruction and coastal studies. Recent research (as of 2024) has utilized v9.1 for documenting lithological changes in Greenland core sediments and comparing laboratory-based particle size analysis techniques.
If you are a sedimentology student or a researcher stuck because you cannot find the tool, here is what you need to do:
Generates grain size distribution curves and statistics reports automatically. gradistat v 91 link
Enter your sieve data (weights) or laser granulometer data (percentages) into the designated input sheet. Run Analysis: Execute the macros to calculate statistics.
Automatically classifies sediments using the Folk and Ward method. Enter your sieve data (weights) or laser granulometer

Gradient-based methods form the backbone of modern machine learning and econometrics. From logistic regression to deep neural networks, algorithms rely on computing gradients of loss functions to update model parameters iteratively. A tool named "Gradistat" would logically provide a suite of functions for gradient checking, automatic differentiation, or statistical tests on gradient distributions. Version "91" suggests a mature release—potentially the 91st iteration—implying significant debugging, feature additions, or API changes. In open-source projects, such version numbers are common (e.g., v0.91 indicating a beta release). Thus, "Gradistat v 91" could represent a statistical toolbox optimized for high-dimensional gradient analysis. Mastering Particle Size Distribution: The Ultimate Guide to
Whether you are studying coastal sediment dynamics or atmospheric dust provenance, GRADISTAT v9.1 remains an essential tool for turning raw measurements into meaningful scientific data.

Sedimentary analysis relies on measuring the distribution of physical grain sizes to reconstruct historical depositional environments, assess soil permeability, and evaluate coastal dynamics. Doing these calculations by hand or configuring raw mathematical formulas for hundreds of samples is notoriously tedious.
