Late Cretaceous paleosols as paleoclimate proxies of high-latitude Southern Hemisphere: Mata Amarilla Formation, Patagonia, Argentina
Sign Up to like & getrecommendations! Published in 2018 at "Sedimentary Geology"
DOI: 10.1016/j.sedgeo.2017.11.001
Abstract: Abstract Although there is general consensus that a global greenhouse climate characterized the mid-Cretaceous, details of the climate state of the mid-Cretaceous Southern Hemisphere are less clearly understood. In particular, continental paleoclimate reconstructions are scarce… read more here.
