Abstract:
Scar Crags and Dale Head North in the English Lake District host mineralised veins enriched in Energy Critical Elements (ECE) specifically, bismuth, cobalt and copper. A limited number of studies in the 1970s investigated the mineralogy and inferred the genesis of these veins as being related to the intrusion of the Lake District batholith.
This study investigates the geology, mineralogy, mineral chemistry, and paragenesis of these two mineralised areas. The results highlight the ubiquitous presence of Co-Fe-Ni-sulfarsenides in both deposits and the presence of some mineral species, hitherto unreported. Scar Crags samples contained high concentrations of cobalt, often present within arsenopyrite, meanwhile cobalt is of minor importance at Dale Head North, where copper and arsenic are the primary metals. A sequence of events, with As-Co-Ni-bearing fluids infilling the veins after an initial stage of quartz and chlorite precipitation is the most striking resemblance between the two mineralised systems, potentially indicating a common process for Co-rich vein-type deposits in the area. If so, understanding such processes could prove vital in aiding exploration in other terranes.
