Hi Christian.

This is a legitimate question, as if one were to query dba_tables, the column "tablespace_name" is null for a global temporary table (GTT).

The segments are created in the users default temporary tablespace.

select temporary_tablespace
  from dba_users
 where username=USER
/

Assuming 8i R3 - here is a good start:
http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a85397/statem3e.htm#2062857

and this should help:

extents in temporary segments:
