Dramatic scene in story about black gold (7)
I believe the answer is:
tableau
'dramatic scene' is the definition.
(I've seen this before)
'story about black gold' is the wordplay.
'story' becomes 'tale' (synonyms).
'about' indicates putting letters inside.
'black' becomes 'b' (abbreviation as in pencil classifications).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'tale' enclosing 'b' is 'table'.
'table'+'au'='TABLEAU'
'in' acts as a link.
(Other definitions for tableau that I've seen before include "Motionless group on stage" , "A scene with silent motionless group of people" , "Group of models representing a scene" , "Pageant" , "Group of people arranged as for a painting say" .)
