Seasonal climatic instability in the western Chinese Loess Plateau during Marine Isotope Stages 12–10

open access: yesScientific Reports, 2023
Because of similar astronomical background, Marine Isotope Stage (MIS) 11 is viewed as an analogue of the Holocene, but the evolution of seasonal climatic instability during MIS 11 has not been well investigated.

Evolution of the volcanic mechanism in the central part of the Urumieh-Dokhtar magmatic arc

open access: yesJournal of Economic Geology, 2021
Introduction Cenozoic volcanic activities in the Urumieh-Dokhtar Magmatic Arc (UDMA) have occurred in three main pulses of Eocene, upper Oligocene-Pliocene, and Pio-Quaternary (Dilek et al., 2010, Sayari, 2015).

Depositional Record and Geochemistry Constraints on the Late Miocene–Quaternary Evolution of the Taiyuan Basin in Shanxi Rift System, China

open access: yesFrontiers in Earth Science, 2022
The formation and evolution of the Shanxi Rift System are topics of interest because of its unique geometry and critical position in the North China Plate. However, it is not easy to delineate the late Cenozoic tectonic processes.

Tectonostratigraphic History of Mesopotamian Passive Margin during Mesozoic and Cenozoic, South Iraq. [PDF]

open access: yesKirkuk Journal of Science, 2008
Passive margin of Mesopotamian zone formed by two tectonic phases: opening and closing phases. Opening tectonic phase (Permian-Jurassic) represents the beginning of Wilson cycle. This phase includes three stages: pre-rifting, rifting and post-rifting. In

Erosional and Tectonic Evolution of a Retroarc Orogenic Wedge as Revealed by Sedimentary Provenance: Case of the Oligocene – Miocene Patagonian Andes

open access: yesFrontiers in Earth Science, 2020
Sedimentary provenance techniques have been widely applied in foreland basin settings to understand tectonic and magmatic processes by tracking the exposure and erosion of distinct sediment source areas through time.
