Published in 2020 at "Cretaceous Research"

DOI: 10.1016/j.cretres.2020.104470

Abstract: Abstract The Hell Creek Formation and overlying Fort Union Formation record a geologically rapid base-level rise that was approximately contemporaneous with the K/Pg extinction and deposition of Chicxulub-impact indicators. An outstanding question that remains is… read more here.

Published in 2020 at "Lithos"

DOI: 10.1016/j.lithos.2020.105835

Abstract: Abstract Late Cretaceous felsic and latest Cretaceous-Paleogene basaltic volcanic rocks are exposed throughout the Kyrenia Range, N Cyprus. Field mapping of the key, well-exposed western range indicates that the felsic volcanics are mainly crop out… read more here.

Published in 2019 at "Marine and Petroleum Geology"

DOI: 10.1016/j.marpetgeo.2018.11.032

Abstract: Abstract Basins containing Paleogene organic-rich shales formed in a saline lacustrine environment are widespread in eastern China, and they provide sources of hydrocarbons in numerous petroleum fields. However, research on these basins has been patchy,… read more here.

Published in 2020 at "Palaeogeography, Palaeoclimatology, Palaeoecology"

DOI: 10.1016/j.palaeo.2020.109755

Abstract: Sedimentological, micropaleontological and geochemical studies of IODP Leg 302 boreholes, M0004A and M0002A, drilled on the Lomonosov Ridge near the North pole, are reported to construct chronostratigraphy and helped unravel Paleogene palaeoclimatic. These studies concluded… read more here.

Published in 2017 at "Tectonophysics"

DOI: 10.1016/j.tecto.2016.11.035

Abstract: Abstract Sedimentary basins often develop above internal zones of former orogenic belts. We hereafter consider the Malay Peninsula (Western Sunda) as a crustal high separating two regions of stretched continental crust; the Andaman/Malacca basins in… read more here.

Published in 2022 at "Molecular phylogenetics and evolution"

DOI: 10.1016/j.ympev.2022.107485

Abstract: Inferring accurate biogeographic history of plant taxa with an East Asia (EA)-North America (NA) is usually hindered by conflicting phylogenies and a poor fossil record. The current distribution of Chamaecyparis (false cypress; Cupressaceae) with four… read more here.
