Path of gold section (5)
I believe the answer is:
orbit
'path' is the definition.
(orbit is a kind of path)
'gold section' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'section' becomes 'bit' (both can mean part).
'or'+'bit'='ORBIT'
'of' acts as a link.
(Other definitions for orbit that I've seen before include "field of activity" , "Stellar path" , "Field of influence" , "Sphere of action" , "Area of influence - eye socket" .)
