Microscale pyroxene weathering features in bole beds constrain rapid Deccan eruption tempo at the K-Pg boundary

This Zenodo archive contains the datasets, supplementary materials, computational workflows, and analysis scripts associated with the manuscript “Microscale pyroxene weathering features in bole beds constrain rapid Deccan eruption tempo at the K–Pg boundary.” The archive is intended to support reproducibility, and reuse of the methods and results presented in the study. The archive includes: 1. Supplementary Documentation SUPPLEMENTAL MATERIAL.pdf – Detailed supplementary text describing the analytical methods, data processing procedures, assumptions, and supporting information used in the study. 2. Image Processing and Pyroxene Denticle Analysis Scripts edge detection and histogram.py edge highlighted by green color.py These Python scripts were developed for image processing, edge detection, visualization, and histogram-based analysis of pyroxene denticles used to quantify microscale weathering features in bole-bed samples. 3. Bayesian Reconstruction of Deccan Eruption History Piyush_Chron1.0StratOnly.ipynb Project.toml Manifest.toml These files contain the computational workflow and software environment required to reconstruct Deccan Traps eruption histories using the Bayesian eruption-modeling framework implemented in Chron.jl. The analyses include reconstructions both with and without eruptive hiatuses and provide the basis for estimating eruption rates and associated volcanic volatile emission rates. 4. Eruption-Rate Datasets and Supporting Spreadsheets Ambenali_Red_Bole_Eruption_Rates_with_blank_rows.csv Poladpur_Red_Bole_Eruption_Rates.csv Table...Input of Eruption Rate estimation.xlsx These datasets and spreadsheets contain the input parameters, intermediate calculations, and eruption-rate estimates used in the reconstruction of Deccan volcanism and the calculation of comparative volatile emission rates presented in the manuscript. Together, these materials provide the data, code, and documentation necessary to reproduce the image-analysis workflow, Bayesian eruption-rate reconstructions, and volatile-emission calculations described in the associated study.
