These specimens are all rock samples collected at meteorite impact craters around the world. Many are from some
of the largest astroblemes (craters) and show lithologies typical of such structures, including melt breccias, injection
breccias, impact melts etc. There are a wide variety of types listed. In all specimens one side has been polished
while the other is left raw. Photographs generally show the polished side but random pieces show the raw side for
comparison. None of the specimens are coated or were sprayed with water prior to being photographed, so what you
see is what you get.

In all instances a penny is used for scale. The penny measures 20mm / 0.75 inches wide. All specimens are a nice
manageable size and almost all are slices. We have been careful to select examples that show the best lithology of
each type.

Specimens are listed in geological order, oldest to youngest from time of impact. Almost 2 billion years of impactites
are offered.
Impactite I
Gardnos, Norway - Cambrian 500 myrs
A dark rock containing abundant white clasts of shattered rock from the
basement lithology. An uncommon impactite.
Gardnos - £6/$10
An interesting comparison is shown above. The specimen on the left is a slice
of  impactite from Gardnos, the specimen on the right is a lunar meteorite.
The colour and nature of the inclusions are almost identical showing how
similar the lithologies of the moon and earth can appear.
Lake Hummeln, Sweden - Ordovician 465 myrs
Impact breccia incorporating the dark red and green basement rock among veins of quartz.
Hummeln - £5/$8 each
Paasselka, Finland - Triassic 229 myrs
One of the best looking impact melt breccias with abundant, pronounced clasts in a dark matrix. The impact that
formed the crater during the Triassic shattered Palaeoproterozoic rocks with an age of 1.885 billion years and
incorporated them into the melt breccia. Excellent stuff.
Paasselka - £6/$10 each
As with the Gardnos material, the Paasselka impact melt
breccia is remarkably similar to some lunar meteorites. The
NWA 2727 lunar meteorite specimen to the left has a
colour and similar nature to the inclusions to the terrestrial
Paasselka rocks. Although the chemical make-up can vary
considerably sue to the minerals present the similarity of
the overall appearance cannot be denied suggesting both
were formed by the same processes.
Soderfjarden, Finland - Late Ediacaran 560 myrs
An old impactite that occurred just at the end of the Ediacaran as the Cambrian explosion of life was about to begin.
This material is a nicely brecciated pseudotachylite with orange/pink and black grey granite and quartz inclusions.
Soderfjaden - £6/$10 each
Sudbury, Canada - Palaeoproterozoic 1849 myrs
The Sudbury impact crater is one of the largest and
oldest on earth. The immense structure is rich in
minerals formed when the crater was formed and
the massive amounts of molten rock flowed across
the basin. As a result the area is heavily mined and
the mineral rich soils are perfect for agriculture. The
image to the right shows the large elliptical shape of
the heavily eroded crater. In the top right section of
the ellipse you can see the extensive agricultural
field networks. The large lake at the NE end of the
crater is Lake Wanapitei, which was formed by
another meteorite impact in the late Eocene. What
are the odds of two being so close together yet
nearly 2 billion years apart?

Two main forms of impactite are known from
Sudbury: a black breccia rich in white mineral clasts,
and a rarer golden, metal rich melt.
Sudbury breccia
Sudbury Gold - £6/$10 each
Sudbury 'gold'
Its not really gold, but it sure looks like it! This is some of the metal rich mineral deposits that are actively mined.
Some of the nicest pieces we have seen in a long time.
