Description
Forty rock samples from the Guano-Guayes skarn property in the Pelly Mountains, Yukon Territory, were analyzed for rare earth elements (REE) via neutron activation. The data describes REE values from syenite, dikes, skarn, and sedimentary rocks, normalized to chondritic values. Analysis suggests fluid circulation transported trace REE from zircon-rich dikes into surrounding rocks.
Use Cases
Compare REE patterns normalized to chondritic values between syenite and standard crustal rocks to assess geochemical anomalies.
Analyze REE enrichment, particularly light REE, in zircon-altered dikes to model selective partitioning during crystallization.
Model fluid circulation pathways by tracing REE patterns from syenite and dikes into adjacent skarn or sedimentary rocks.
Strengths
Data is derived from 40 distinct rock samples collected from a defined geological property.
Analytical method is specified as neutron activation, a standardized technique for REE quantification.
Geological context is detailed, including skarn dimensions (300m wide, 70m thick, 1100m long) and rock types (syenite, dikes, sedimentary).
Limitations
Sample size is limited to 40 samples, which may not capture full spatial variability of the deposit.
Data format is HTML, not a structured table, requiring extraction for quantitative analysis.
No raw numerical data or column definitions are provided in the available description.
