Rapid Creek Formation Geology and Mineralogy, Yukon 2012

A 2012 three-week field program collected mapping, geochemical samples, and phosphate minerals from the Rapid Creek Formation in Yukon. The formation is a phosphorite-rich ironstone facies with alternating phosphate and siderite-rich mudstones. Secondary minerals from veins and nodules include rare phosphate species like apatite, augelite, and arrojadite-group minerals.

Use Cases

• Identify rare phosphate mineral occurrences based on the list of collected secondary minerals.
• Analyze the composition of phosphorite-rich ironstone facies based on the described alternating beds.
• Study the mineralogy of phosphate nodules based on the identified species like satterlyite and wolfeite.
• Map geological features of the Rapid Creek Formation based on the field mapping program.

Strengths

• Field data collected over a three-week program in 2012.
• Description lists specific rare phosphate minerals like apatite, augelite, and arrojadite-group minerals.
• Geographic scope is defined as the Rapid Creek Formation in the Richardson Mountains, Yukon.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data freshness should be verified; last metadata update was 2026-04-17.
