Chandindu Formation Stratigraphy in the Ogilvie Mountains, Yukon

A 150 to 420-meter-thick siltstone-dominated mixed carbonate-siliciclastic succession formally defined for the early Neoproterozoic Fifteenmile Group. Ten sections of the Chandindu Formation are presented, including a proposed type section, to aid correlation of Proterozoic records in northwest Canada. The data originates from the Government of Yukon and was last updated on April 17, 2026.

Use Cases

• Correlating stratigraphic successions within a basin based on the ten presented sections
• Analyzing ocean redox conditions and early eukaryote evolution based on archived biosphere information
• Modeling depositional environments based on described muddy tidal flat and subtidal facies cycles
• Investigating syn-depositional faulting and paleohighs based on descriptions of rift-inherited basin topography

Strengths

• Formally defines a stratigraphic unit with a thickness range of 150 to 420 meters
• Includes ten detailed sections and proposes a type section for standardization
• Archives information on early Neoproterozoic biosphere evolution, including ocean redox

Limitations

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