Just a quick question, as I've not been able to find out in anything I've read so far. I know that using the wrong radiometric dating methods brings back wrong results, e.g. using K-Ar on some lava that is practically still warm is useless.
My question is- If I were to date a series of much too young or much too old lavas with K-Ar dating, even though it could not possibly tell me the age of the lava, what kinds of numbers would I get? I'm particularly interested to know if the technique would still be able to tell oldest from youngest, or if the numbers would be fairly random? Would the same apply to other radiometric techniques?
