Berserker Range
The Berserker Range is a mountainous region located on the eastern and northeastern boundary of the city of Rockhampton in Central Queensland, Australia. Within it lies Mount Archer National Park. It has been designated the ''Berserker Range Environmental Protection Area'' by the Rockhampton Regional Council. The southernmost part of the range reaches the Fitzroy River at Broadmount, east of Rockhampton.
==Geology==
The range is composed of a diverse group of mostly igneous rocks dating from the Devonian to Early Triassic Periods. It has its origins in the early Permian period around 275 million years ago, when the original segment of continental crust stretched and subsequently sagged, leading to the development of two faults and subsequent volcanic activity. Much of the rocky outcrops and peaks of elevated areas are composed of masses of rhyolite and dacite and known as ''Elliott Rhyolite''. These masses then erode, with the deposits forming a dark grey material known as ''Sleipner Member''. Not all the elevated areas are rhyolite; Mount Dick and Mount MacDonald, are mainly composed of breccia.
