Title: Hot Rocks/Coke or Meteorites??
Post by: Junkman on February 27, 2010, 12:42:12 PM
Hmm, this got me thinking. Hot rocks and coke. We simply discard them without giving them much thought BUT I was watching a programme on 2 meteorite hunters using Metal Detectors out in the desert to find really big meteorites.

I wonder how many mud covered HotRocks/Coke we just chuck away are actually meteorites??. They have peppered earth since it was formed and are indiscriminate where they land so it could be the Arizona desert or Chepstow ???.

Has anyone actually found a definite Meteorite??

Interesting thought there Junkman, I was only thinking this after the last rally where I got two strong audio signals but no visual signal on the Explorer, when I dug them up it was a large piece of what looked like slag/coke but the minelab's don't generally detect coke and the signal was off the bottom of the screen. Makes you think.

Same here. My Trident 2 gives a double 'hit' on coke and I was spread around the site but not in any qty. It's the old question of how did it get there??.

Some people say from Victorian Nightsoil dumping but there was non of the other items associated with nightsoil dumping

Some people say its from Steam Traction engines used for ploughing but I can't see them being used on that site as it was pasture not arable.

I'm damn sure they are small bits of space junk...........

I think it was arable not to long ago but the pieces I found didn't look like the normal coke, unfortunately I hedged the two bits I found but Taff had a piece that was similar.

I too have been interested in this apparently the best place to find them is the salt flats in america because they stand out so much against the white ground. I have struggled a bit with the T2 and hot rocks if im honest, so used to the se not picking them up i do get the good signal one way rubbish the other but i have also read somewhere that with the T2 even if its a good signal one way then i should dig it. Saying  that everytime i have its been a hotrock.

My T2 ignore them (or should I say- I ignore them). After a while you get a good feel for the Audio and visual ID for them and ignore them.

Re hotrocks and coke, I never bother to really look at them at they are covered in mud but the next few will be taken home for a closer look. Having just seen some google images of Meteorites, they do look suspiciousley similar 8) 8)

This IS a meteorite. Now, If I dug that in a field I would just discard it as Coke ???

Here is an interesting website on detecting for Meteorites.

I was talking to a farmer about the amount of coke I found on his land and he said his father used to have a coke house where basically he put soil in a big metal tray and would burn coke underneath it. This was to sterilise the soil and kill off any weed seeds then he'd use this soil for starting off seedlings which would be weed/disease free. Afterwards the ashes(with some unburnt lumps of coke)would be scattered around the fields as ash is supposed to sweeten the soil. Makes sense how it gets there now or maybe martians have been dumping it here!

On the last chepstow rally I found 2 pieces of so called coke.They both gave me a strong positive signal on my explorer.The Ist one I dug up I still got in my coat pocket(I will clean it as soon as I have time)The second one I put in the edge(I know where it is if needed).

I'm sure that 'some' of the hotrocks/Coke we dig are small meteorites. Why would Explorers identify them with a signal when Explorers don't 'do' coke??

I'm going to keep my next lot I find and take them home for cleaning and further investigation.

It's funny isn';t it, we get excited about finding a broken in half buckle that's 500 years old when we could be throwing away bits from outer space that are Millions and millions of years old ??? ??? ??? ???
