Digital Lithogeochemical Map of Bavaria: Geochemical Rock Units

Bavaria's lithogeochemical map at 1:25,000 scale delineates 184 geochemical rock units derived from geological formations. It provides statistical parameters like the 50th and 90th percentile for element concentrations measured by XRF and ICP-MS. The data represents the current state of knowledge from the Bavarian State Office for the Environment.

Use Cases

• Analyze regional geochemical background values based on percentile statistics for 184 rock units
• Map spatial distribution of element concentrations across Bavaria using the derived element cards
• Identify geological units with similar formation conditions based on the integrated mapping approach
• Study the relationship between lithology and geochemistry for surface and near-surface rocks

Strengths

• Defines 184 distinct geochemical rock units for detailed regional analysis
• Provides statistical parameters (50th and 90th percentile) for element concentrations
• Derived from the current digital geological map of Bavaria using an integrated mapping approach

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• The accuracy is at best 25 meters and cannot provide specific, site-level predictions
