متن کاملExtraterrestrial spherules in glacial sediment from the Transantarctic Mountains, Antarctica: Structure, mineralogy, and chemical composition
Abstract-Silicate and glassy spherules of probably extraterrestrial origin have been discovered in glacial till from localities in the Beardmore glacier region, Tramantarctic Mountains, Antarctica. These spherules are similar in structure, appearance, and composition to spherules found in deepsea sediments and in Greenland. Most spherules have a shiny and smooth dark surface, while some show a ...
متن کاملEclogite-facies metamorphism preserved in tectonic blocks from a lower crustal shear zone, central Transantarctic Mountains, Antarctica
In the Geologists and Miller Ranges of the central Transantarctic Mountains, mafic and ultramalic tectonic blocks occur in an Early Cambrian amphiboliteto granulite-facies lower crustal transpressional shear zone. Mafic blocks consist of garnet + clinopyroxene symplectite + hornblende + plagioclase + quartz + ilmenite f orthopyroxene f biotite;mineral compositions in these blocks generally refl...
متن کاملGold bearing veining linked to transcrustal fault zones in the Transantarctic Mountains (northern Victoria Land, Antarctica)
Gold bearing veining linked to transcrustal fault zones in the Transantarctic Mountains (northern Victoria Land, Antarctica)" (2007). Related Publications from ANDRILL Affiliates. Paper 20. Summary Gold mineralization is associated with the paleo-Pacific margin of Gondwana and is related to processes of subduction/accretion and magmatism. Northern Victoria Land (Antarctica) was part of this mar...
متن کاملPliocene Nothofagus Wood from the Transantarctic Mountains
Subfossil wood fragments up to 10 cm long and 2 cm in diameter recovered from a locality thought on the basis of diatom deposits to be upper Pliocene-lower Pleistocene (Oliver Bluffs, Sirius Formation, 85°1 O'S., between 1800 and 1900 m in the Transantarctic Mountains) were sectioned for identification. Degradation prevented observation of some wood features, but others were well preserved. All...
