Abstract: For a binary quartic form $ \phi$ without multiple factors, we classify the quartic $ K3$ surfaces $ \phi(x,y)=\phi(z,t)$ whose Néron-Severi group is (rationally) generated by lines. For generic binary forms $ \phi$, $ \psi$ of prime degree without multiple factors, we prove that the Néron-Severi group of the surface $ \phi(x,y)=\psi(z,t)$ is rationally generated by lines.
