Tektite Indonesia rare flow banding from atmospheric re entry & burst bubble & regmaglypts

32 grams 30mm in size 800,000 years old

Very rare flow banding on two surfaces

Rarely on meteorites but especially rare to be on a tektite

Flow banding refers to viscous streaks and lines created by the molten material cooling and solidifying during its high-speed passage through Earth's atmosphere. These features are often visible in the meteorite's fusion crust and can be found on its leading edge, providing clues about the meteorite's orientation and the extreme conditions it experienced during atmospheric entry.

How flow banding forms Atmospheric Entry: As a meteorite/tektite enters the atmosphere, intense heat and friction cause its surface to melt. 1700 deg c

Molten Material: This molten material flows over the surface in streaks, often following the path of least resistance.

Solidification: As the meteorite moves through the atmosphere, the molten flow cools and solidifies, preserving the flow lines as part of the fusion crust.
