GEOMAGIA50 is a paleomagnetic database containing 3,702 absolute paleointensity estimates from 159 published studies. The archive compiles all published absolute geomagnetic intensity determinations for the past 50,000 years, sourced from natural geological materials and archaeological artifacts. It is maintained by the University of Helsinki and aggregates data from peer-reviewed journals.
Use Cases
- Modeling geomagnetic field intensity over the past 50,000 years using the paleointensity estimates.
- Analyzing the distribution and reliability of data points from the 159 source studies.
- Correlating geomagnetic intensity variations with geological or archaeological timelines.
- Validating new paleointensity measurements against the compiled 3,702 published estimates.
Strengths
- Contains 3,702 individual paleointensity estimates.
- Aggregates data from 159 separate published studies.
- Covers a temporal range of 50,000 years.
Limitations
- Data scope is limited to the Holocene epoch (last 50,000 years).
- Relies on published data which may have inconsistent measurement methodologies across studies.
- Specific sample locations, material types, and measurement uncertainties are not detailed in the provided description.
