🏫 My first paper was featured on the China University of Geosciences (Beijing) official news: 自动化定量提取锆石深度剖面U-Pb定年数据新方法.
📰 Summary
The article highlights our newly developed Automated Depth Profiling Technique (ADEPT) — a quantitative workflow for extracting U-Pb ages from zircon depth profiles, published in Journal of Geophysical Research: Solid Earth.
Key findings:
- ADEPT combines ARIMA anomaly detection, LOESS smoothing, and PELT segmentation to objectively identify age signal plateaus
- Bayesian validation: >84% of plateau data consistent within 1× RMSE
- Applied to 4,615 Himalayan leucogranite zircons, revealing four major magmatic pulses at 45 ± 2, 35 ± 3, 19 ± 4, and 9 ± 2 Ma
- Introduced ΔAge parameter, showing a systematic eastward decrease across the Himalaya — consistent with eastward slab tearing/delamination models
