Tektites are chunks of glassy material found in a number of
locations across the globe. Most are blackish in colour and
show signs of exposure to intense heat. The exceptions to this
are the beautiful (and rare) green Moldavites from Eastern
Europe, the yellowish Libyan glassites, and the green-grey
Darwinites. We sell two types, Irgizite or Indochinite.
Moldavites are often an exquisite emerald green colour, and
are frequently used in jewellery making.
There has been much controversy about the genesis of
tektites: their appearance and distribution in 'strewn
fields' suggests a meteoric origin, but their composition is
more consistent with a terrestrial formation.
Geologists generally believe tektites were created when
massive impacts hurled molten surface rocks high into the
atmosphere: remelting on re-entry producing the
characteristic shape and evidence of ablative heating. Other
types may have been formed in situ by the extreme energies
of a meteoric impact.
However, an increasing number of experts feel that they
could in fact suggest an extraterrestrial origin. The debate
still goes on...
