When scientists are trying to date the layers in an entire stalagmite,
they take samples from bottom to top, so coring in from the side not a
practical alternative. They pretty much have to saw the thing in half

John, what kind of rocks can you afford to date? Are we talking common
minerals, or are you more in the semi-precious to precious stone range now?

On NPR this mornig I heard that Australia was going to be doing research on
weather by cave formations. They only have 100 to 150 years of weather info on
most of their country. The present dry spell has them wanting what they hope
will be up to 1000 years of data.

Oh no you don't, I'm not responding to that one and starting another
meltdown.
All I have to say about that is that if you can only date a rock, you
need to get some plastic surgery or some personality lessons.

Can/could a speleothem be sawn off in a cave, taken to the lab where a
core, etc. removed, then returned to the cave and glued back in place?

I don't think it is necessary to remove entire formations for age dating
any more (if it ever was). Relatively small cores can be drilled out leaving

But if the earth is only 8 to 10,000 years old...why is the age of speleothems

Mark,
Maybe one of the specialists in this area will respond with more
detailed information but yes, speleothems can be dated by analyzing the
ratios of radioactive elements. They do have growth rings but the ones
you see with the naked eye do not equate to dates like tree rings - it
is a lot
