A new tool for calculation and visualization of U–Pb age data: UPbplot.py

Abstract

This paper presents usages, examples, and mathematical backgrounds of a Python script, UPbplot.py, which was newly developed for calculation and visualization of U–Pb age data. The script is a collection of various functions to deal with the one- and two-dimensional weighted means, concordia ages, and concordia-intercept ages on the conventional (Wetherill) and Tera–Wasserburg concordia diagrams for U–Pb age data. This script can calculate those ages and output images including concordia diagrams, bar plots, and histograms.
