Stratigraphy of the Lower Palaeozoic Bowers Supergroup, Northern Victoria Land, Antarctica: Preliminary Results From the 2012–2013 Korean Antarctic Geological Expedition
Since Korea built the first Antarctic research station on King George Island, South Shetland Islands, the Korea Polar Research Institute (KOPRI) has conducted geological projects on the island, including research on stratigraphy, petrology, geochronology, and pedology. The second Korean Antarctic research station is now being built, with its opening scheduled for March 2014, and is located on Northern Victoria Land (NVL), East Antarctica. KOPRI has started to shift its focus of geological research to the Transantarctic Mountains (TAMs), including NVL. Among many research targets, the lower Palaeozoic stratigraphy of NVL will be the first issue to tackle. The tectonics and related basin evolution of NVL, which differs from those of the main part of the TAMs, has been the core geological issue of the region. To better understand the basin evolution history, KOPRI is planning a multi-year research programme spanning such geological methods as sedimentology, palaeontology, structural geology, and petrology. As a reconnaissance study, a group of sedimentologists and palaeontologists undertook fieldwork in the Eureka Spurs, ca. 220 km northwest of the new station, during the austral summer season of 2012–2013. Here, the results of the reconnaissance and the strategy for further research are presented.
