tektites are found on all continents and are highly varied
in their colour, shape and pattern. Glass meteorites are fragments
of glass that have entered our atmosphere and have been greatly
heated while falling to earth. The scars of the heat are evident
on the surfaces of most pieces and some pieces show quite
unique patterns or shapes that make them highly sought after
meteorites may be from wandering meteorites impacting the
atmosphere and some may be from massive volcanic activity
from this planet where material was erupted high into the
atmosphere, scientists are still trying to unravel the mysteries.
formations on glass meteorites are:
and jagged faces – formed as the outside harden and the fluid
inside forces cracks to open in the crust
– formed by molten glass stretching as it enters the atmosphere
drop – a dumbbell where the 2 halves have separated
– where one face has melted to form a flange on one face.
– where a large molten mass has hardened on the outside before
impact and only the shell fragments are left.
of the most famous glass meteorites are Moldovites from Czech
Republic, these are a green glass and have very well formed
crusts showing patterns.
famous form of glass tektite is the Australite. Australites
come in a wide range of shapes and generally have a smooth
face. The most famous form is the flanged Australite which
carries a perfect ring around its circumference similar to
Saturn with its rings. This ring is caused by molten glass
being forced outwards as the tektite enters the atmosphere.
