Tearing out from hard rock! (7)
I believe the answer is:
granite
'hard rock' is the definition.
(I've seen this before)
'tearing out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'tearing' is an anagram of 'GRANITE'.
'from' is the link.
(Other definitions for granite that I've seen before include "Coarse-grained igneous rock" , "Get rain (anag) - rock" , "Igneous rock, generally composed of feldspar and mica and quartz" , "Hard stone from Tangier" , "A very hard rock from Tangier" .)
