| Summary: | The Anakie Metamorphic Group of central Queensland is a multiply deformed sequence of psammitic to pelitic metasedimentary and mafic igneous rocks. Although the depositional age is still uncertain, this paper presents K-Ar dates from four samples which indicate that the sequence was deformed at about 500 Ma in the Middle Cambrian, and thus forms part of the Delamerian-Ross Orogen of southern Australia and eastern Antarctica. Lithologically and structurally similar rocks in the Lolworth-Ravenswood Province, farther north in Queensland, may also be part of this belt. The significance of an older age of about 540 Ma from a fifth sample is uncertain. A sixth sample gave a younger age of about 470 Ma and may be partly reset.
