The rock is composed of quartz white magnetite black and red garnet almandine . These minerals are very common ingredients of heavy mineral placer deposits. I cannot imagine any other genesis so I assume that this rock is a former heavy mineral concentrate which got buried and finally metamorphosed to a rock-type similar to quartzite.

Zirconium: Mineral information data and localities.
Zirconium is a silvery-white metal primarily produced from the mineral zircon although a very small number of deposits are mined for the zirconium oxide baddeleyite instead. Zircon can occur as a by-product of the mining and processing of the titanium minerals ilmenite and rutile as well as a byproduct of tin mining.
