Sedimentary and volcanic rocks from Precambrian to Lower Cretaceous underlie the Tombstone area. The conditions of metamorphism are reflected by the stability field of the tremolite-calcite-quartz-diopside assemblage, with a temperature range between 475° and 525° C assuming 2 kb pressure. This dataset from the Government of Yukon describes mineralogical zoning in host rocks away from syenitic intrusions.
Use Cases
- Model metamorphic temperature-pressure conditions based on the tremolite-calcite-quartz-diopside assemblage.
- Analyze mineralogical zoning patterns based on the decreasing dolomite content in original sediments.
- Study the geological history of the Tombstone Range based on rock ages from Precambrian to Lower Cretaceous.
Strengths
- Temperature of metamorphism is quantified between 475° and 525° C.
- Pressure assumption of 2 kb provides a defined context for analysis.
- Rock age range from Precambrian to Lower Cretaceous provides temporal scope.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the Tombstone Range study area.
