摘要

摘要/ ABSTRACT摘要:在西南极洲Marie Byrd Land的米兰岩(Milan Rock)和墨菲山(Mount Murphy)，从孤立的含植物、可能是河流沉积序列的砂岩中提取的碎屑锆石年龄显示了可能的中白垩纪(95—105 Ma)沉积时代。在阿蒙森海发现的年代相近的岩石显示出温暖、潮湿的环境，而这里报告的植物岩的新数据表明，这种环境与当代白垩纪中期南极非常接近(bbb80°S)

Cover successions on early Paleozoic basement in Marie Byrd Land, West Antarctica – evidence for Cretaceous plant-bearing rocks at South Polar latitudes

ABSTRACT Detrital zircon ages from sandstones in isolated plant-bearing, probably fluviatile sedimentary successions at Milan Rock and Mount Murphy, Marie Byrd Land, West Antarctica indicate probable mid-Cretaceous (95--105 Ma) depositional ages. Rocks of similar age reported from the Amundsen Sea have indicated warm, humid environments and the new data reported here for plant-bearing rocks would now place such conditions close (>80°S) to the contemporary mid-Cretaceous South Pole

期刊介绍： Aims: New Zealand is well respected for its growing research activity in the geosciences, particularly in circum-Pacific earth science. The New Zealand Journal of Geology and Geophysics plays an important role in disseminating field-based, experimental, and theoretical research to geoscientists with interests both within and beyond the circum-Pacific. Scope of submissions: The New Zealand Journal of Geology and Geophysics publishes original research papers, review papers, short communications and letters. We welcome submissions on all aspects of the earth sciences relevant to New Zealand, the Pacific Rim, and Antarctica. The subject matter includes geology, geophysics, physical geography and pedology.
