Description
A compilation contains 1,251 sulfur and 1,622 lead isotope analyses from nearly 450 mineral occurrences. The dataset includes a hierarchical deposit model and mineralization age for each site, primarily located in Yukon with others in British Columbia, Alaska, and the Northwest Territories. It is formatted for GIS integration and subject to periodic updates.
Use Cases
Analyze spatial correlations between S isotope values and deposit model classifications across 450 occurrences.
Compare Pb isotope signatures against mineralization age to trace metallogenic events in the Canadian Cordillera.
Integrate the flat file into a GIS platform for spatial querying of isotopic data by geographic region.
Identify regional trends by mapping the distribution of Pb isotope analyses from the 1,622 available measurements.
Strengths
Contains 1,251 sulfur and 1,622 lead isotope analyses, providing substantial isotopic measurements.
Covers nearly 450 mineral occurrences across multiple jurisdictions.
Includes a hierarchical deposit model and mineralization age ascribed to each occurrence for interpretive context.
Formatted as a flat file (shapefile, geodatabase, text) for easier integration into GIS platforms.
Limitations
The exact number of rows and columns is unknown, limiting precise assessment of dataset scale and structure.
Data from Alaska primarily relies on a 1989 compilation, which may be temporally stale for some analyses.
Sample data and column definitions are unavailable, complicating initial data exploration and modeling.
Provenance
Source
Government of Yukon, distributed from GeoYukon.
Collection Method
Compilation building upon prior work by Collin Godwin (1988) and the Gaccetta and Church (1989) database for Alaska.
Time Range
null
Freshness
Subject to periodic updates; last platform update was March 2026.
Geography
Primarily Yukon, with additional occurrences in British Columbia, Alaska, and the Northwest Territories.
