Transmission electron microscopy analysis of shock veins in the meteorite JeseniceAmbrožič, Bojan (Avtor) Šturm, Sašo (Avtor) Vrabec, Mirijam (Avtor) chondriteshock stageshock veinsmetal-sulfide globulestetrataenitetransmission electron microscopyMeteorite Jesenice is a weakly (S3) shocked ordinary chondrite from Slovenia. The shock event was violent enough to cause localized partial melting of the meteorite and the formation of shock veins. Inside the shock veins, metal-sulfide globules were found, which provided evidence for a post-shock cooling rate of 2.2·105 Ks–1 – 7.4·103 Ks–1. From the mineral paragenesis of the shock veins, shock pressure and peak shock temperature were deduced as 2.5–15 GPa and 1500–2150 °C, respectively. We provide evidence that shock veins were formed via a shear and friction mechanism. Furthermore, the confirmed presence of ordered FeNi metal (tetrataenite) found in the matrix indicates that the shock occurred in the parent body of the meteorite Jesenice.Geološki zavod Slovenije20252025-12-24 08:20:33Neznano24904UDK: 55ISSN pri članku: 0016-7789DOI: 10.5474/geologija.2025.010COBISS_ID: 259317763sl
