Accepted 25 November 2008 Magnetic lineaments trace major fault zones, including NNW to NNE trending transtensional fault systems Available online 6 December 2008 that appear to control the emplacement of Neogene age McMurdo volcanics. These faults represent splays from a major NW–SE oriented Cenozoic strike-slip fault belt, which reactivated the inherited early Paleozoic Keywords: – Aeromagnetic anomalies structural architecture. NE SW oriented magnetic lineaments are also typical of the Admiralty Block and fl Transantarctic Mountains re ect post-Miocene age extensional faults. To re-investigate controversial relationships between strike-slip Inheritance faulting, rifting, and Cenozoic magmatism, we combined the new aeromagnetic data with previous datasets Cenozoic magmatism over the Transantarctic Mountains and Ross Sea Rift. -

U.S. Geological Survey and The National Academies; USGS OF-2007-1047, Short Research Paper 045; doi:10.3133/of2007-1047.srp04 Basal Adare volcanics, Robertson Bay, North Victoria Land, Antarctica: Late Miocene intraplate basalts of subaqueous origin 1 2 3 3 3 N. Mortimer, W.J. Dunlap, M.J. Isaac, R.P. Sutherland, and K. Faure 1GNS Science, Private Bag 1930, Dunedin, New Zealand ([email protected]) 2Research School of Earth Sciences, Australian National University, Canberra, ACT, Australia. Present address: Dept. of Geology & Geophysics, University of Minnesota, Minneapolis, MN 55455, USA 3GNS Science, PO Box 30368, Lower Hutt, New Zealand Abstract Late Cenozoic lavas and associated hyaloclastite breccias of the Adare volcanics (Hallett volcanic province) in Robertson Bay, North Victoria Land rest unconformably on Paleozoic greywackes. Abundant hyaloclastite breccias are confined to a paleovalley; their primary geological features, and the stable isotope ratios of secondary minerals, are consistent with eruption in a subaqueous environment with calcite formation probably involving seawater. In contrast, the lavas which stratigraphically overlie the hyaloclastites on Mayr Spur probably were erupted subaerially. K-Ar dating of eight samples from this basal sequence confirms the known older age limit (Late Miocene) of the Hallett volcanic province. Geochemical data reveal an ocean island basalt-like affinity, similar to other Cenozoic igneous rocks of the Hallett volcanic province. If a submarine eruptive paleoenvironment is accepted then there has been net tectonic or isostatic post-Late Miocene uplift of a few hundred metres in the Robertson Bay-Adare Peninsula area.

Cape Adare, Borchgrevink Coast
Measure 2 (2005) Annex L Management Plan for Antarctic Specially Protected Area No. 159 CAPE ADARE, BORCHGREVINK COAST (including Historic Site and Monument No. 22, the historic huts of Carsten Borchgrevink and Scott’s Northern Party and their precincts) 1. Description of Values to be Protected The historic value of this Area was formally recognized when it was listed as Historic Site and Monument No. 22 in Recommendation VII-9 (1972). It was designated as Specially Protected Area No. 29 in Measure 1 (1998) and redesignated as Antarctic Specially Protected Area (ASPA) 159 in Decision 1 (2002). There are three main structures in the Area. Two were built in February 1899 during the British Antarctic (Southern Cross) Expedition led by C.E. Borchgrevink (1898-1900). One hut served as a living hut and the other as a store. They were used for the first winter spent on the Antarctic continent. Scott’s Northern Party hut is situated 30 metres to the north of Borchgrevink's hut. It consists of the collapsing remains of a third hut built in February 1911 for the Northern Party led by V.L.A. Campbell of R.F. Scott's British Antarctic (Terra Nova) Expedition (1910-1913), which wintered there in 1911. In addition to these features there are numerous other historic relics located in the Area. These include stores depots, a latrine structure, two anchors from the ship Southern Cross, an ice anchor from the ship Terra Nova, and supplies of coal briquettes. Other historic items within the Area are buried in guano. Cape Adare is one of the principal sites of early human activity in Antarctica. -
