Geology North of Mount Mye, Yukon: Cambrian-Devonian Volcanic and Sedimentary Package

A Cambrian-Devonian volcanic and sedimentary package with an aggregate thickness greater than 1600 meters underlies the northeast Anvil area north of Mount Mye in central Yukon. The Government of Yukon published this geological description, which details units including the Cambrian-Ordovician Vangorda formation phyllites, Ordovician-Silurian Menzie Creek formation basalts, and Ordovician-Devonian Road River Group shales. The dataset was last updated on April 17, 2026.

Use Cases

• Model stratigraphic sequences based on described Cambrian-Devonian volcanic and sedimentary units.
• Analyze volcanic rock distribution based on the Ordovician-Silurian submarine basalt flows and volcaniclastic sediments.
• Study sedimentary basin formation based on the inferred north-trending Ordovician-Silurian syndepositional normal fault.
• Investigate metamorphic effects based on the hornfelsing indicating a shallowly buried Cretaceous batholith extension.

Strengths

• Describes a geological sequence with an aggregate thickness greater than 1600 meters.
• Provides specific thicknesses for units, including a 120-meter exposed phyllite unit and a >900-meter basalt sequence.
• Identifies specific geological formations (Vangorda, Menzie Creek, Road River Group) and their age ranges.

Limitations

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