Lead Isotopes in Archaeology: An Interactive Textbook

This package streamlines lead isotope provenance analysis by using PCA and geochron slope distribution to identify endmembers. It calculates precise Euclidean distances to ore databases—with optional fractionation corrections—and determines the probability of a sample's subregional origin using XGBOOST analysis..

Python implementation of the Zartman–Doe (1981) and Haines–Zartman (1988) plumbotectonics Pb-isotope evolution models, validated against the tables in the original papers.
