Code

The code folder contains Jupyter notebooks that utilize a Python kernel to visualize and analyze the data.

TAS_plot.ipynb: plots the total alkali vs silica composition of samples

composite_pystrat.ipynb: generates the composite stratigraphic column thicknesses

date_bar_plots.ipynb: makes the date bar plots of CA-ID-TIMS U-Pb dates

detrital_zircon_analysis.ipynb: conducts statistical analyses and generates visualizations of detrital zircon data from this study and others that are integrated for comparison
