The Palaeozoic Lizard Complex of southwestern England is composed of a peridotite body with gabbro and intruded by granitic rocks. The peridotites are bounded by amphibolite schists and metasedimentary rocks with those in the southern region also intruded by granodiorite sheets. These granodiorites sheets are coeval with the Man-of-War Gneiss on islets south of the Lizard headland. To the north, the Lizard Complex is in tectonic contact with the Devonian Gramscatho Group. Zircon and baddeleyite U-Pb-Hf isotopic data and zircon REE chemistry presented here provide more accurate resolution of the Lizard Complex's evolution. The Old Lizard Head Series at the southern point of the Lizard headland is intruded by granodiorite bodies with ages of 488 ± 11 and 499 ± 7 Ma, indistinguishable from the 498 ± 11 Ma age for the Man-of-War Gneiss. Thus the rocks bounding the Lizard Complex are interpreted as a Cambrian (Miaolingian or older) volcano-sedimentary and felsic intrusions package.
