    Asteroid collision showered the earth with meteorites

    Hum,

    An asteroid collision showered the earth with meteorites for millions of years.
    An enormous collision between two asteroids created a meteorite shower that rained down on earth for millions of years.
    Meteorites of up to 1.5 kilometres in size impacted with the earth.
    German researchers have now determined the time of the collision, which is still responsible today for a third of the meteorites that impact the Earth.

    The enormous collision between the two asteroids occurred 470 million years ago.

    "One was at least hundred kilometres largely, other even several hundred kilometres" - Mario Trieloff of mineralogical Institut of the University of Heidelberg.

    When the two giants collided, the rock was exposed to a hundred of thousands of bars of pressure.
    Scientists already had a suspicion that a whole class of meteorites - the so-called l-Chondrite - came from the collision between two large asteroids. Trieloff and his colleague have used a new method to date the cataclysmic asteroid crash with more accuracy - It occurred 470 million years ago.
    The greatest possible deviation amounts to only six million years, writes the researchers in the January edition of the technical periodical "Meteoritics and Planetary Science"

    Vor knapp 500 Millionen Jahren ist offenbar ein Kleinplanet mit erheblicher Masse im Asteroidengürtel zwischen den Bahnen von Mars und Jupiter durch Kollision zweier Objekte auseinandergebrochen. Messungen Heidelberger Forscher um Mario Trieloff bekräftigen jetzt diese These, die bislang wegen zu ungenauer Altersangaben nicht hinreichend belegt werden konnte.

    Hum,
    on the website there is an image of the Ghubara meteorite which was found in Old Kalkgestein(?) in Sweden that was used with similar meteorite fragments from Jiddat al Harasis in Oman to date the collision to 467.3 million years ago...

    Having an asteroid break up as it approaches Earth is not the only way to end up with multiple craters.

    Within the asteroid belt that orbits the sun between Mars and Jupiter, collisions between asteroids sometimes occur. The resulting fragments can then rain down on Earth. Simon Kelley, a geologist at the Open University in England, says that such a collision occurred 470 million years ago, and many of those fragments travelled to Earth. In fact, some of the fragments still are impacting Earth today.
