| Sep 23, 2013 at 14:04 | comment | added | naf | @Dan Petersen: Choose a closed point on the fibre of $f$ over each (scheme theoretic) generic point of $Y$ and let $Z$ be the Zariski closure of these points. | |
| Sep 23, 2013 at 13:50 | comment | added | Dan Petersen | @ulrich: Oh, even better! Because any proper variety $X$ has a modification $X' \to X$ which is projective? Or is there a simpler argument? | |
| Sep 23, 2013 at 11:26 | comment | added | naf | @Dan Petersen: Proper and surjective is all one needs to get such a subvariety. | |
| Sep 23, 2013 at 8:53 | comment | added | Dan Petersen | That's a nice reference. In fact the only point of the argument that uses projectivity is in order to find a closed subvariety $X' \subset X$ mapping generically finitely onto $Y$. | |
