Book Description
The seventh German Antarctic North Victoria Land Expedition (GANOVEX VII) took place in the austral summer of 1992/93. Geological and geophysical investigations were carried out on both sides of the Ross Sea: on King Edward VII Peninsula, northwestern Marie Byrd Land, in the east, and in northern Victoria Land and the adjacent Oates Coast in the west. Apatite fission-track data from the Alexandra and Rockefeller Mountains on Edward VII Peninsula indicate that the thermal history of the eastern rift flank of northern Victoria Land was different from that of the western rift shoulder. Tectonic and isostatic control factors on the landscape evolution of the coastal mountains of northern Victoria Land and their relationship to the Ross Sea rift are discussed in one paper of this volume. Regional metamorphic rocks appear on both sides of the Ross Sea. They were affected by the Ross orogeny and are related to the formation of the Gondwana supercontinent. The type and degree of metamorphism of the Early Palaeozoic regional metamorphic rocks of the Swanson Formation in westernmost Marie Byrd Land were studied and compared with metamorphic rocks in northern Victoria Land and on South Island, New Zealand. A paper deals with the origin of the amphibolites in the Priestley Formation of the Wilson Terrane of northern Victoria Land. The composition of the volcanic parent rocks of the Bowers Terrane metamorphic rocks in northern Victoria Land and their plate tectonic setting are discussed in another paper. The gravity measurements of previous GANOVEX expeditions were continued in Victoria Land between Brimstone Peak and Coulman Island, south of Lillie Marleen Hut, and in the Oates Coast region. Two-dimensional models are used to interpret the data obtained along two profiles from the polar plateau to the coast.

Book Description
The geoscientific results of the Victoria Land Traverse, 1959-60 are presented with interpretations and conclusions. The major geographical discoveries, the Arctic Institute Range and the Rennick Glacier, are treated and descriptions and locations given. The presence of a vast ice thickness, which in many cases exceeds 2.0 km. is reported covering Victoria Land and is shown to conceal a major subglacial depression. Subglacial rock topography influences the relief of the ice surface of Victoria Land as seen upon comparison of seismic and altimetric results. The presence of prolonged seismic surface noise is reported and attributed to low temperature phenomena. (Author).

Book Description
The Australide orogen, the southern hemisphere Neoproterozoic to Mesozoic terrane accretionary orogen that forms the palaeo-Pacific margin of Gondwana, is one of the largest and longest-lived orogens on Earth. This book brings together a series of reviews and multidisciplinary research papers that comprehensively cover the Australides from the Tasman orogen of eastern Australia to the Neoproterozoic and Palaeozoic orogens of South America, taking in New Zealand and Antarctica along the way. It deals with the evolution of the southern Gondwana margin, as it grew during a series of terrane accretion episodes from the late Proterozoic through to final fragmentation in mid-Cretaceous times. Global perspectives are given by comparison with the Palaeozoic northern Gondwana margin and documentation of world-wide terrane accretion episodes in the Late Triassic-Early Jurassic and mid-Cretaceous. The Tasmanides of eastern Australia, and the terrane histories of New Zealand and southern South America are given comprehensive up-to-date reviews.

Book Description
The papers in this volume cover the orthogneisses and the Pan-African granitoids and charnockites, in addition to studies on the regional metamorphism and the structural evolution of central Dronning Maud Land (DML). The results presented in this volume fill gaps in the knowledge of the geological structure and history of cDML and thus find interest in the Antarctic research community.
