INSPIRE-compliant Yukon Bedrock Geology Map

Local geology is a crucial part of the characterisation of any exploration target. The 1:250,000 scale geological map of the Yukon was used to segment the geochemical samples before thresholding, and to characterise the geology of sample sites and their surroundings.

MineMatch® and the underlying mineral deposit models use rock terminology that comes from the CGI’s GeoSCIML lithology vocabulary.

To enable optimal cross-referencing to the rock-type terminology used in the MineMatch® mineral deposit models, the Yukon Geological Survey's bedrock geology was translated to match the terminology of the GeoSCIML vocabulary, against which MineMatch® is standardised.

The styling for the INSPIRE compliant geology map follows the styles recommended by INSPIRE based on the attribute "older named age". The legend for this portrayal is shown below.

 Translation to Matcher Standard Terminology

inspireEffective matches require a pre-processing step where the YGS lithology codes are translated and aligned with the terminology present in the GeoSCIML vocabulary. The individual rock types were parsed out and aligned before being merged into a final column, where the listed order of rock types was retained.

A list of all the rock names parsed out of the aligned rock type field, together with the GeoSCIML names to which they were translated for use in this study can be viewed by clicking on the thumbnail to the right (or below).

The aligned rock types and the Bedrock Geology layer in the interactive Yukon Mineral Targets map are INSPIRE compliant.INSPIRE is an international directive legislated in the European Union by the European commission. It standardises the publication of geospatial data. INSPIRE is broken into 34 spatial themes, of which Geology is one. INSPIRE compliance means that the terms are aligned with INSPIRE codelists and that data encoding follow specific standards which facilitate interoperability and open exchange of data.
