Short summary
Short summary
Hydrothermal magnetite TR41 from the Troodos ophiolite (Cyprus) is proposed as a candidate reference material for LA-ICP-MS U–Pb geochronology. Despite low U concentrations (<1 µg/g), TR41 is sufficiently homogeneous and yields robust Tera–Wasserburg regressions. Validated via U–Pb dating of coexisting andradite (92.04 ± 2.23 Ma) and blind-tested against associated garnet and apatite, TR41 provides accurate matrix correction, enabling wider application of magnetite U–Pb dating.

Short summary
The analysis by electron microprobe of platinum-group minerals, gold and cinnabar particles from heavy mineral concentrates of the Elbe showed a broad compositional variation of Os–Rus–Irs–(Pt) alloys as well as Pts–Fe alloys. The comparison with the literature showed that different sources account for the heavy mineral concentrate. This compositional variation of the alloys is also of interest for other placers of platinum-group minerals worldwide.
