Few years ago, we were a small team carrying out a regional geological mapping campaign in the South of New Caledonia. On the rocky ridges surrounding the ferricrete plateaus of the Prony Bay, we mapped dunite and harzburgite with varying degrees of serpentinization, as well as gabbros dykes.

Le Kaymar is a F-Ba-Fe-(Cu-Pb-Zn) lodes field located in the Variscan basement at the periphery of a granite stock, on the edge of a Permian basin, in the French Massif Central. Workings on this small deposit dates back the Gallo-Roman times for lead-silver, the 19th century for iron ore and the 20th century for fluorspar. Between two sessions of office work, the current lockdown in Europe is an opportunity to store, label and photograph my reference mineral collection.
