Geochemistry (Workflow 2)

Anomaly Identification

The 99th percentile was used to classify samples as "enhanced" in any element for the purposes of a MineMatch® description.

MineMatch® reports for each cluster of anomalies list the anomalous elements which characterise the cluster, and include, in the "Comments" column of the report, a statement as to whether the element is anomalous within the entire population, the lithology-specific population, or both populations.

Steve Amor provides an overview of geochemical data presentation and interpretation for exploration, which includes a discussion of the advantages of using percentiles to set anomaly thresholds.
