Datasets for "Systematics of helium diffusion sinks in apatite demonstrated by 4He/3He degassing experiments and modeling"

Supporting datasets for Guo et al., "Systematics of helium diffusion sinks in apatite demonstrated by 4He/3He degassing experiments and modeling" submitted to Geochimica et Cosmochimica Acta for review as of 01/29/2025 (V1).

Updated 05/14/2025(V2) for revision.

Updated 05/25/2025 (V3) during proofing. Added missing files for modeling results(Cooling 3 and cooling 4 for Fig.8).

List of files:

• 1. Blank corrected data of step-heating diffusion experiments.
• 2. U-Th-Sm isotopic data and (U-Th)/He ages.
• 3. DIFFSIM forward modeling results.
• 4. C++ source code for DIFFSIM simulation.

Contribution:

• HG and MT designed the analytical approach and lab routine for the diffusion experiments.
• MT set up the noble gas lab and arranged sample irradiation.
• HG performed the diffusion experiments and data analyses.
• PZ wrote the DIFFSIM codes. HG performed the simulations.
• All authors contributed to the discussion of the results.
