Zone between the Earth’s crust and core (6)

I believe the answer is:

mantle

(Other definitions for mantle that I've seen before include "Loose cloak, shawl" , "Gas lamp part; cloak" , "Cloak and shelf over the fireplace" , "Layer below earth's crust" , "Cloak or loose outer garment" .)

I've seen this clue in The Times.
