Ageing band got in scuffles on coach (6,6)
I believe the answer is:
carbon dating
'ageing' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'band got in scuffles on coach' is the wordplay.
'scuffles' indicates an anagram (I've seen 'scuffling' mean this (I've seen this in other clues)).
'on' is a charade indicator (letters next to each other).
'coach' becomes 'car' (as in a train coach or car).
'band'+'got'+'in'='bandgotin'
'bandgotin' is an anagram of 'bondating'.
'bondating' after 'car' is 'CARBON DATING'.
Can you help me to learn more?
(Other definitions for carbon dating that I've seen before include "Method of estimating age" , "Means of finding age of prehistoric items" , "The use of isotopes to determine age" , "ageing process" , "scientific process" .)
