Supporting dataset for "Heterogeneous stagnant slab controls focused crustal recycling and volcanic clustering."

This dataset accompanies the paper “<b>Heterogeneous stagnant slab controls focused crustal recycling and volcanic clustering.</b>”It includes two files containing seismic and thermochemical data used in this study.<br><b>NEChina_rf_2025.tar.gz</b> – Raw receiver function waveform data, processed with a Gaussian low-pass filter of 0.5.<br><b>Thermochemical_model.dat</b> – Thermochemical structure of the upper MTZ constrained by seismic observations and mineral physics modeling. Each column represents: latitude, longitude, potential temperature (Tpot), Tpot uncertainty, basalt fraction (f), f uncertainty, water content (Cw), and Cw uncertainty.

本数据集配套于论文《异质停滞板片控制聚焦式地壳循环与火山群集》，包含本研究中使用的地震与热化学数据文件共两份：
**NEChina_rf_2025.tar.gz**——原始接收函数（receiver function）波形数据，经0.5高斯低通滤波处理。
**Thermochemical_model.dat**——由地震观测与矿物物理建模约束得到的上地幔过渡带（upper mantle transition zone, MTZ）热化学结构。各列依次代表：纬度、经度、位温（potential temperature, T_pot）、位温不确定性、玄武岩组分占比（basalt fraction, f）、组分占比不确定性、含水量（water content, C_w）以及含水量不确定性。
