Development of exploration concepts for SN-TA pegmatites

Full report title Development of exploration concepts for SN-TA pegmatites: Use of host rock associations and alteration haloes

Summary

The pegmatite of this study is in a Barrovian-style terrain, localised in a major shear zone, and in or near mafic-ultramafic sequences, thus explaining many of the anomalous features in its mineralogy, texture and structure.

Exploration parameters defined are mineral geochemistry, geochemical dispersion haloes and geochemically anomalous cross-cutting mafic dykes.
