I have some bunker coal from the Titanic on my desk. Taken 3.8Km down. So far it hasn't exploded.
The literature is full of examples of 600,000 year and older ice core data from samples takes at 3-4 km down.

I will try and find the lecture where I picked that up...explode perhaps ..certainly..the wrong word..but I thought the lecturer said because of the pressure it expanded rapidly and they could not read it ... I will look for it.
Thanks Peter.

Here is the lecture ..Yale..

And you will see the lecturer says the ice gets brittle and actually uses the words that it explodes...useful cores limited to 8000 bc and depth 600 to 1300 mtrs.

Edit... I forgot to direct viewers to the spot in the video where I picked up the notion of the ice exploding and the limitations that brittle ice puts on the research...go to minute 49 and you will hear the lecturer say what he said and know where I got the notion...a matter of less than a minute.
Now I watching another lecture and he certainly mentions 400,000 year icecore????
