Causes And Effects Of The
2350 BC Middle East Anomaly
Evidenced By Micro-debris Fallout,
Surface Combustion And Soil Explosion
by Marie-Agnès Courty
Occurrence in a previously recorded thick tephra deposit of particles identical to some of the mysterious layer and resemblance of its original pseudo-sand fabric with the exploded one of the mysterious layer confirms that the later is contemporaneous with the tephra deposit It has been however impossible to find typical tephra shards in sites located at a few km around the one with the tephra deposit The restricted occurrence of the later suggests that the massive tephra accumulation can no longer be considered as a typical fallout derived from the dispersion of material from a terrestrial volcanic explosion.
Meteor clue to end of Middle East civilisations
by Robert Matthews, Science Correspondent
"Studies of satellite images of southern Iraq have revealed a two-mile-wide circular depression which scientists say bears all the hallmarks of an impact crater. If confirmed, it would point to the Middle East being struck by a meteor with the violence equivalent to hundreds of nuclear bombs. The catastrophic effect of these could explain the mystery of why so many early cultures went into sudden decline around 2300 BC. They include the demise of the Akkad culture of central Iraq, with its mysterious semi-mythological emperor Sargon; the end of the fifth dynasty of Egypt's Old Kingdom, following the building of the Great Pyramids and the sudden disappearance of hundreds of early settlements in the Holy Land."
