Triassic magmatism and tectonic setting of Eastern Tianshan, NW China: constraints from the geochemistry and zircon U–Pb–Hf isotopes of granitoids in the Yamansu area

Frontiers in Earth Science, 2023
Introduction: To provide constraints on the Triassic tectonic setting of Eastern Tianshan, an integrated study was conducted on the geochronological and geochemical data for granodiorites, monzogranites, and two-mica granites from the Yamansu area on the

Geochemistry of sandstones and shales from the Ecca Group, Karoo Supergroup, in the Eastern Cape Province of South Africa: Implications for provenance, weathering and tectonic setting

Open Geosciences, 2017
Geochemical compositions of twenty-four sandstone and shale samples from the Ecca Group were analysed to decipher their provenance, paleoweathering conditions and tectonic setting. The shales have high Fe2O3, K2O, TiO2, Ce, Cu, Ga, La, Nb, Nd, Rb, Sc, Sr,

Mineralogy and Geochemistry of Sediments from Lake Tuz

Hittite Journal of Science and Engineering, 2021
Lake Tuz is in a closed basin, in the center of the Anatolia (Turkey). The lake has shallow hypersaline water. In this study, mineralogical and geochemical features of the lake sediments sampled by core drillings were investigated.

Multi-scale depositional successions in tectonic settings [PDF]

Earth-Science Reviews, 2020
<p><span>Observations in sedimentary basins affected by deformation show that the fault-induced depositional accommodation, at various spatial and temporal scales, is closely linked to basin kinematics. The tectonically-driven sediment infill displays the history of deepening and shoaling facies that are controlled ...
