La Primavera Caldera Geological Map and Evolution Data, 1:30,000 Scale

La Primavera caldera geological data covers an 856 km² area in the western Trans-Mexican Volcanic Belt. The dataset includes a 1:30,000 scale map and likely contains information on volcanic deposits, domes, and the caldera's evolution from ~95,000 years ago to 6.4 thousand years ago. It was authored by José Luis Macías and last updated on figshare in April 2026.

Use Cases

• Modeling caldera evolution based on described pyroclastic, lacustrine, and volcaniclastic deposits.
• Assessing volcanic hazard zones for urban planning based on the mapped caldera-rim and intra-caldera features.
• Studying post-caldera volcanic activity timelines based on the described eruption sequence from 93.8 to 6.4 thousand years ago.
• Analyzing the interaction between volcanic activity and lacustrine sedimentation within the caldera depression.

Strengths

• Covers a specific 856 km² area with a detailed 1:30,000 scale map.
• Integrates previous studies with new field data, suggesting a consolidated source.
• Provides temporal context for events spanning from approximately 95,000 to 6.4 thousand years ago.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
