The fees provided below are subject to change. The costs for analysis differ depending on the type of meteorite. In this way we meet all the requirements for new meteorite naming (see What's in a name?). Also, the University of Alberta Meteorite Collection is an official Type Specimen Repository for meteorites-one of only three in Canada.

We have the necessary tools at the University of Alberta to gather all information required to classify a new meteorite of any type. You can watch our "How To Spot a Meteorite" video on this page for more information and you can also use our Meteorite Reporting System to fill out a report and upload photos for an expert to look at. If your rock passes all these tests, you might have yourself a meteorite. When a meteor falls through Earth's atmosphere, the outer surface of the rock melts, forming what's known as a fusion crust. Examine the outer-layer of the specimen for a thin, black, eggshell-like crust.If your specimen does, it's likely slag or some other stony matter. A true meteorite will not have any holes or bubbles at all. Check for holes or bubbles in the specimen.

Nearly all meteorites contain iron-nickel metal and attract magnets easily.

Test the specimen's magnetism using a standard fridge magnet.

Many meteorites (typically iron meteorites) are quite dense and feel heavier than most Earth rocks.

Check if the specimen feels unusually heavy for its size.

Luckily, the University of Alberta has some meteorite experts on hand who have outlined some preliminary tests anyone can conduct to tell the difference between space rocks and impostor rocks from Earth. Most people will find neat-looking porous rocks and assume they have found a meteorite, but often they've found slag, chert, or pyrite. Meteorites, a.k.a rocks from outer space, are a lot more rare than you might think.
