Cliffe Hill Quarry is a geological Site of Special Scientific Interest on the western outskirts of Markfield in Leicestershire. It is a Geological Conservation Review site. This quarry exposes volcanic and sedimentary Charnian rocks dating to the Precambrian eon. It was probably then a volcanic island. An unusually homogeneous form of the rock diorite is sometimes called markfieldite because it is found in the village. The site is private land with no public access.
