Study
Made Of Meteorite
Russians Find It Was Of Rare Variety Of Hexadrite
MOSCOW
(UP) - One of the largest meteorites to collide with the
earth in modern times, the massive one which crashed some
250 miles north of Vladivostock on the night of Feb. 12,
was of a comparatively rare variety known as "hexadrite,"
Soviet scientists studying splinters from the meteor have
determined.
It
contained iron, nickel, cobalt, and a small amount of phosphorous
and sulphur.
Other
scientists still are working in the area where the meteor
fell , with one crew excavating to reach what apparently
was the main body of the meteor. It is buried more than
35 feet into the soft ground of the sparsely-inhabited area.
The crater it formed is 210 feet in diameter.
Thirty-five
other splinter craters have been mapped, most of them 45
to 75-foot diameters.
Reports
from the maritime provinces showed that the earth collided
with "a small planet or asteroid" weighing 1080
tons and only the fact that both the earth and asteroid
were going in the same direction prevented a major shock,
Radio Moscow said.
"A
report received at Alma Ata Kazakhstan from Academician
V. G. Fessenkov, heading the Soviet Science Academies mission
studying the Sikote Alin meteorite shows this event was
probably unique in the history of mankind," Radio Moscow
said.
FASTER
THAN EARTH
"The
earth collided with a small planet or asteroid. Calculations
show that the meteorite was overtaking the earth at a small
angle to its orbit at a speed of some 19.9 miles per second,
which considerably exceeds the speed of the earth.
"Consequently
the meteorite reached the earth's surface causing local
damage. Some of its fragments buried themselves deep in
the ground, forming numerous craters.
"An
air wave passed in the direction of flight of the meteorite.
The fall of the meteorite was not accompanied by an explosion
as happened in the case of the great Tunguska meteorite
which was flying in a direction opposite to that of the
earth.
The
Tunguska meteorite, greatest known to fall in historic times,
landed in Siberia with a great explosion and speckled many
square miles with craters. It flattened trees away from
the explosion for scores of miles around.
Radio
Moscow said: "The Sikbota Alin meteorite has an interesting
chemical composition. Its crystalline structure is another
proof of its cosmic origin. The expedition is continuing
its studies."
