Especially industries like coal-burning power plants, foundries and metal processing produces such spherical particles. That's why one has either to go in the stratosphere to collect micrometeorites or to use unpolluted sources like Antarctic wells or ice or sediments - from the times where there wasn't human pollution, to be able to isolate them. Especially in the late 70ies and early 80ies it was quite a fashion among the collectors to try to find micrometeorites by filtering rainwater. Best!

You should see some residue on the bottom in time. Cover a magnet with Saran wrap, wax paper or some other type of material. Pick up magnetic material in tray with your magnet and set on paper to dry. Observe material with a good- strong microscope. Some of what you see will be spherical balls- those are the micrometeorites. Steve from the nuggetshooter forum(http://www.nuggetshooter.ipbhost.com/index.php?showforum=4) posted that 2 years ago.? There were great links and photos but the sites are long gone.? I quote, "If you're not having any luck hunting macrometeorites, try hunting micrometeorites. You'll never get skunked." Can someone with a microscope try this and post pictures if they can? [Erik] Received on Tue 26 Jan 2010 07:34:12 AM PST |
