Government of Yukon data describes the diachronous Richthofen-Conglomerate Formation transition within the Jurassic Laberge Group. The succession records submarine gully and slope apron progradation from the Middle Pliensbachian to the Early Toarcian. It provides constraints on the timing of arc-continent collision and the closure of the Whitehorse Trough seaway.
Use Cases
- Model submarine slope and gully depositional systems based on described lithostratigraphic subunits.
- Analyze the timing of arc-continent collision based on constraints from slope turbidite and pelagic sedimentary rocks.
- Study deep marine basin evolution based on the described succession of marine shales, sandstones, and conglomerates.
- Investigate the relationship between relative sea-level rise and clastic input variations based on the intercalated sequence.
Strengths
- Data is from a 'superbly exposed' contact on the west flank of Brute Mountain.
- The succession provides temporal constraints from the Middle Pliensbachian to the Early Toarcian.
- Data is published by the Government of Yukon, an authoritative source.
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 a single exposure in the Yukon.
