Entry Type
Specimen TSNB498
Description
A shard of partly oxidised sulphide, grey black in colour, encrusted on both sides with intergrown crystals of colourless smithsonite (to 4 mm), pseudo-dodecahedral in habit, with curvilinear faces.
The specimen has been analysed by EMPA-WDS and LA-ICP-MS as part of a study of the causes of colour in smithsonite (Weall 2023; Southwood et al. 2025) who hypothesised that likely chromophore elements are present in insufficient quantity, either individually or in combination, to colour the mineral. Analytical data is presented in Exhibit 2.
