This Pultusk specimens was found by polish meteorite hunter in june and september 2005.
He was very lucky to find 4 big specimens (105g, 220g, 245g and 301g) in total of 870g.
With help of local people he was able to find area where was a big possibility
to locate meteorite specimens. He spend several weeks search suspect locations. Finally his
work was rewarded.
This meteorites is still in verry good condition. I have cleaned 108.5g specimen and
after lose 3g of rust and soil I have made pretty looking complete specimen, still with
black crust.
One half of my other 254g specimen I have cut in full slices to see how it looks inside. Results
was incredible. This specimen have still some fresh parts inside. I must say that this
meteorite is verry hard and solid, without any cracks. Cutting was much slower that I should
expect from ordinary H5 chondrite. Maybe this was one of the reasons why it is only little
weathered. Polishing was also not soo easy as I expected at the beginning.
I have send one slice to Silesian University in Sosnowiec for investigation. There profesor
L.Karwowski, President of Polish Meteoritical Society, confirmed that this is real Pultusk
meteorite and define weathering grade for only W1. One week later, sample from 245g specimen
was microprobed in Warsaw, and results are identical with original "old" Pultusk.
Search for specimens in Pultusk strew field is extremely difficult. In this area was front line
of World War II, so ground is full of iron. This eliminate any metal detector and the only
acceptable method is our own eye and magnet in hand. The other problem is ammount of bigger
specimens. In this fall was many thousands of stones, but in size of 1g to several grams
(~10-30g) named Pultusk Pea. But there was not many bigger specimens. Also we must remember
that after bright and loud meteorite fall, local people and members of Polish Academy of
Science search for specimens for months and years.
So this discovery is much more incredible that We can think.
