Ground turned up, delivers rocks (10)

I believe the answer is:

pulverised

'ground' is the definition.
('ground'->'pulverized' is in my internal thesaurus and 'ize'->'ise')

'turned up delivers rocks' is the wordplay.
'turned' shows that the letters should be reversed in order.
'rocks' indicates anagramming the letters.
'up' in reverse letter order is 'pu'.
'delivers' is an anagram of 'lverised'.
'pu'+'lverised'='PULVERISED'

I've seen this clue in The Independent.
