Four models of fission track annealing in apatite are compared with measured fission track lengths from Ocean Drilling Program Leg 129. The maximum temperature experienced by the sampled bed is between 16°-21°C at 96 Ma, and measured fission tracks are 14.6 +/- 0.1 µm long. The dataset was created by P.J. Vrolijk to evaluate annealing models against a high-resolution temperature history.
Use Cases
- Validate fission track annealing models based on measured track lengths and paleotemperature data.
- Analyze the thermal history of Cretaceous ocean crust based on conductive heat flow model assumptions.
- Compare predictions from published and unpublished annealing models against empirical geological data.
- Study the relationship between apatite composition and fission track annealing behavior.
Strengths
- Temperature history resolution is described as high due to shallow burial and simple tectonic history.
- Provides a specific paleotemperature maximum (16°-21°C) and timing (96 Ma).
- Includes precise measurement of fission track lengths (14.6 +/- 0.1 µm).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
