Quarry mineral (9)
I believe the answer is:
limestone
'quarry mineral' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for limestone that I've seen before include "building material" , "Rock of calcium carbonate" , "Sedimentary rock consisting mainly of calcium" , "Caves in here perhaps" , "Tie lemons up in sedimentary rock" .)
