| Mar 5, 2018 at 4:37 | comment | added | Basics | @JasonStarr, then $D$ is an elliptic fibration over an elliptic curve. I doubt if $D$ is a $K3$ surface. | |
| Mar 4, 2018 at 20:30 | comment | added | Jason Starr | What about a threefold $X$ fibered over a rational surface with curves that are elliptic curves, where $D$ is the inverse image of an anticanonical divisor in the surface, and where at least one of the elliptic curve fibers contained in $D$ is a multiple elliptic fiber? | |
