Reports of slate being quarried (5)
I believe the answer is:
tales
'reports' is the definition.
(tale is a kind of report)
'slate being quarried' is the wordplay.
'being quarried' indicates anagramming the letters (the word is broken up or quarried).
'slate' is an anagram of 'TALES'.
'of' acts as a link.
(Other definitions for tales that I've seen before include "accounts" , "provided for defective juries" , "Stale kind of stories" , "Stories, fables" , "They might be tall" .)
