Meteorites.....Tektites

After reading Makaws post on meteorites I wondered if any one has found any Tektites? A map of the strewn fields of Australia shows that they may be in the gold fields. I read that Aborigines called them "ooga" , which means staring eyes. They can be quite valuable. Made of dull black glass material, round in shape, some have a flange around them, kind of like a mushroomed bullet.

Haven't personally, but here is a clip that shows they are not just on the goldfields.

There's a new show on Fox Science channel called Metiorite Men, i watched the second episode last night, and they where in NT just sth/west of the Alice at Henbury Crators, these guys make serious money detecting
for iron metiorites

have to say that im a bit interested as well

got the gear so why not have a play anyone know where to find a map of wa strewn feilds?

A good idea not to smash ya hot rocks to look for gold in them...
Read below...
At the high end of the pricing scale are unusual types such as the diogenite Tatahouine (fell June 27, 1931, Foum Tatahouine, Tunisia). A prime specimen will easily fetch $50/gram while rare examples of lunar and Martian meteorites may sell for $1,000/gram or more — almost forty times the current price of gold!

Ive found a few.
Quite common in the eastern goldfields.
They look like roo poo and end up in the same
places after rain. ie clay pans and salt lakes.

If you think you see one tread on it. If it turns green and breaks up its poo.
If its still solid might be a tectite. Have a closer look.

Here's one I found.

Would love to go out hunting for some of these myself. Reckon it could be a fun day trip with the kids. Are there any descent areas around the perth sector where tectites are/can be found?

AlanWA has made a good observation, tektites have a lower specific gravity than quartz and tend to end up in clay pans and should also be on top of gravel deposits from streams, they have bubbles in them and this makes them lighter for their size. The elongated dumbell size would be easy to spot but the round ones would just look like a black rock. As for meteorites an iron one just looks like a lump of pitted iron but the stoney ones look like a rock with some rusting stains and would register as a hot rock on most detectors. Before you smash the brains out of a hot rock looking for the yellow stuff check it with a strong magnet, if it is magnetic grind off a corner and look for specks of nickle with round little stoney bodies in it. It could be more valuable than gold.

Hey Alan,
what if I put one in my mouth and end up with green teeth......
is that still roo poo :?:

Thanks Pete. Did try to post it
that way but couldn't figure out how to do it.
Will try harder next time....

Crusty Gus.

Probably, but I prefer the step test.
Dont have to bend dont have to stoop down either!
