Does it support compositional data analysis?

Yes, it includes specialized methods for handling compositional data, including Centered Log-Ratio (CLR), Additive Log-Ratio (ALR), and Isometric Log-Ratio (ILR) transformations.

Can I use standard normalization references?

Pyrolite comes with built-in reference compositions for Chondrite, Primitive Mantle, N-MORB, and Upper Crust based on standard literature like McDonough and Sun.

How does it handle major oxide data?

It can automatically normalize compositions to 100% (closure) and perform CIPW norm calculations to determine mineral proportions from major oxide weight percentages.

What types of geochemical diagrams can Pyrolite generate?

Pyrolite can create ternary diagrams, REE spider diagrams, TAS (Total Alkali-Silica) classification plots, Harker variation diagrams, and various tectonic discrimination templates like Pearce diagrams.

Data Science & ML

Performs advanced geochemical data analysis and visualization for igneous, metamorphic, and sedimentary rock compositions.

Pyrolite is a specialized geoscience skill designed to streamline geochemistry workflows within Claude Code, offering robust tools for analyzing and visualizing rock compositions. It enables researchers and geologists to generate publication-ready ternary diagrams, REE spider plots, and TAS classification diagrams directly from pandas DataFrames. Beyond visualization, the skill handles complex compositional data transformations (CLR, ALR, ILR), calculates CIPW norms, and automates the identification of element ratios and anomalies, making it an essential companion for petrological research and mineral exploration.
