Sudbury, Rare Layered Impact Glass, Thick Slab, 190g


Sudbury is an "astrobleme" or impact crater located in northern Ontario Canada. It is the result of a catastrophic meteorite impact that occurred 1.8 billion years ago. The impactor was several kilometers wide and the massive explosion injected large volumes of material into the Earth at the Sudbury site. This event was so destructive, that it punctured the Earth's crust and material from deep inside the Earth's mantle erupted through the wound and mixed with exotic minerals found in the impacting meteorite. This site is now home to some of the world's most productive metal ore mines and this cluster of valuable mineral deposits is a direct result of the impact. If such an event happened today, it would wipe out all life on Earth. Sudbury was, without a doubt, a "civilization killer" - fortunately, humans were not walking the Earth yet when the impact happened!

Material and ores from Sudbury are rich in metals that are rarely seen in such abundances elsewhere, this includes - nickel, copper, iron, cobalt, sulphur, platinum, palladium, iridium, selenium, gold, silver, rhodium, ruthenium, and telerium. 

The material being offered here is a rare example of a layered impact glass that is not commonly seen from this locality. It is similar in look and texture to the "flaedle" impact bombs from the Ries crater in Germany. It shows melt flow features and layering, along with inclusions, and veins.

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. It is a thick slice (slab) that weighs 190 grams. It has a cut face showing the interior matrix. The reverse side is natural and unsanded. Your purchase will include a specimen ID label.
