Abstract
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.
