The timing of the initial collision between the South and North China blocks constraining from the sediments in the eastern Sichuan Basin [PDF]
Scientific Reports, 2023 In this study, detrital zircon U–Pb geochronology, trace element and Hf isotopic compositional data from the Early-Middle Triassic clastic rocks in the eastern Sichuan Basin were obtained to distinguish the sediment provenance and constrain the timing of

Using detrital zircon to reconstruct Neoproterozoic crustal thickness variation in the northwestern margin of the Yangtze Block [PDF]
Scientific ReportsTrace element geochemistry and chronology of zircon are reliable tools for reconstructing sediment provenance and crustal evolution, particularly in contexts where early crustal and rock records are sparse.

A missing continental impact melt sheet signal in the early Earth detrital zircon record [PDF]
Nature CommunicationsImpact-derived melting has been proposed as a significant process in the formation of Earth’s early crust which could mean that impact melts are a source for Earth’s oldest minerals including ancient zircons. However, the source lithology of many Archean

Geochemistry and detrital zircon U–Pb–Hf isotopic data reveal the provenance and tectonic setting of the Xujiahe Formation [PDF]
Scientific ReportsThe depositional age, provenance and tectonic setting of the Xujiahe Formation have been studied, but remain intensely debated. In this study, we focus on the second segment of the Xujiahe Formation (T3x2) as a research object.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Provenance and tectonic implications of the Yanshi bauxite area in Western Henan, China [PDF]
E3S Web of Conferences, 2021 The bauxite layer in Western Henan supplies a large number of bauxite ores and is useful for studying tectonic movement. In this paper, the bauxite samples were selected to carry out LA-ICP-MS detrital zircons U-Pb dating and Hf isotope testing.
