The photo does not show segregation quartz veins, but a metamorphic rock called migmatite. Sometimes a rock is called a migmatite because of the presence of segregation quartz veins in it, but this is a misnomer: segregation quartz forms at hydrothermal conditions, while in migmatites the segregation of minerals into vein-like structures is ...

Limonite deposits are also to be found in connection with iron bearing limestones. The iron content of the limestone is gradually dissolved out by circulating waters and transported by them to some favorable spot, and there the iron is slowly redeposited as limonite, gradually replacing the calcium carbonate of the rock.
