A barred olivine S-type with dendritic crystals of magnetite on its surface.

An S-type with smooth flow lines and elongated opposite ends, one possibly exposing a metal bead.

A barred olivine S-type with near parallel growth of olivine and small magnetite crystals.
A cryptocrystalline S-type with turtle back (knobbly) surface texture and an exposed metal bead resting on a sieve. Won 18th place in 2023 Nikon photomicrography competition.

BEI of the internal structure in a porphyritic olivine S-type. Note the large crystals of olivine in a glassy mesostasis (background light grey). A metal-sulphide bead is exposed on the left and few small vesicles (dark circular voids) are present.

Thin sections (BEIs) and element composition maps of a barred olivine. Note the parallel growth of olivine crystals and the metal bead in the top right of the spherule which has been heavily oxidised.

A porphyritic olivine S-type with a rusty nickel-iron bead on the side and angular olivine crystals.

A colourless porphyritic olivine S-type with several metal and/or sulfide beads spread around the spherule's exterior, probably due to it spinning during atmospheric entry.

Cryptocrystalline urban S-type with an iron-nickel bead on the bottom, and a glass tail on the top rounded by surface tension. The surface of the glass is slightly pitted.

Magnetite dendritic ("tree-like") crystals on the surface of a barred olivine S-type.

A collection of various urban S-types exhibiting different textures.
