Gairloch hosts a small but geologically important belt of ancient base-metal sulphide mineralisation, mainly pyrite-pyrrhotite with copper and zinc sulphides, preserved as stratiform to lensoid VMS-style bodies that have since been strongly metamorphosed and deformed.
The best-studied sulphide mineralisation is in the Palaeoproterozoic Loch Maree Group and is generally interpreted as a strongly deformed, metamorphosed volcanogenic massive sulphide system, commonly described as mafic-siliciclastic or Besshi-type. The main known occurrences are the Kerry Road lens, a nearby small satellite body at Teangadh Bhuidhe Mhor, and an iron-sulphide-rich horizon at North Sidhean Mòr that is intermittently traceable for about 6 km. The Kerry Road lens itself is described as averaging about 4 m thick and extending for roughly 580 m.
Adrok completed 3 scans over a prospective location in for sulphide mineralisation in Gairloch, Scotland. We were asked one question...
Can we remotely detect sulphides in the subsurface?
