Supplementary data for a study on the geochemical characteristics and palaeoclimatic implications of a typical black soil profile in the northern Songnen Plain, Northeast China. The dataset was authored by Han, Xiaomeng and hosted on Harvard Dataverse, with a last update recorded on 2026-05-28. It likely contains measurements from a soil profile used to infer past climate conditions.
Use Cases
- Reconstructing past climate conditions based on geochemical proxies from the soil profile.
- Analyzing soil formation processes and weathering history in the Songnen Plain.
- Calibrating geochemical models for interpreting palaeoenvironmental records in black soil regions.
Strengths
- Data is supplementary to a specific, peer-reviewed scientific study, providing contextual relevance.
- Last update timestamp (2026-05-28) is provided, indicating recent maintenance.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
