A natural oil being refined near a part of Turkey (8)
I believe the answer is:
anatolia
'part of turkey' is the definition.
(I know that Anatolia is part of Turkey)
'a natural oil being refined near a' is the wordplay.
'natural' becomes 'nat' (academic abbreviation).
'being refined' indicates an anagram.
'near' says to put letters next to each other.
'oil' is an anagram of 'oli'.
'a'+'nat'+'oli'+'a'='ANATOLIA'
(Other definitions for anatolia that I've seen before include "Region of Turkey" , "Turkish area" , "Peninsula" , "Asian part of Turkey" , "Asia Minor" .)
