Geochemistry and tectonic setting of Lewisian clastic metasediments from the Early Proterozoic Loch Maree Group of Gairloch, NW Scotland
TLDR
The early Proterozoic Loch Maree Group (LMG) of the Lewisian complex consists of a supracrustal sequence of metasedimentary schists and associated tholeiitic metavolcanic amphibolites within the Archaean basement.About:

The role of hydrothermal fluids in the production of subduction zone magmas: Evidence from siderophile and chalcophile trace elements and boron
TL;DR: In this article, the authors evaluate the processes responsible for the enrichments of certain siderophile/chalcophile trace elements during the production of subduction-related magmas, representative lavas from seven subduction zones have been analyzed for Pb, As, Sb, Sn, W, Mo, Tl, Cu, and Zn by inductively coupled plasma mass spectrometry (ICP-MS), radiochemical epithermal neutron activation analysis (RENA), and atomic absorption (AA).

Geochemistry and provenance of Rhenohercynian synorogenic sandstones: implications for tectonic environment discrimination
TL;DR: In this article, the provenance of synorogenic greywackes from Devonian flysch successions occupying structurally similar positions at opposite ends of the Rhenohercynian zone in SW England and Germany is evaluated.

Neoproterozoic tectonic evolution of the Precambrian Aksu blueschist terrane, northwestern Tarim, China: Insights from LA-ICP-MS zircon U–Pb ages and geochemical data
Wenbin Zhu,Bihai Zheng,Liangshu Shu,Dongsheng Ma,Hailin Wu,Yongxiang Li,Wentao Huang,Junjie Yu +7 more
TL;DR: In this article, the authors conducted a detrital zircon U-Pb geochronological study of both the metasedimentary rocks from the Aksu blueschist terrane and the unmetamorphosed sandstones from the overlying Sinian succession to better constrain the age of the ABT.

Early Paleozoic sedimentary record of the Chinese Altai: Implications for its tectonic evolution
TL;DR: In this paper, the authors conducted a geochemical study of Early Paleozoic metasedimentary rocks to better constrain their provenance and tectonic environment, and found that these rocks have relatively low CIA values (49 to 79), with ICV values (0.73-1.36) higher than that of post-Archean Australian average shale (PAAS), suggesting that they experienced relatively weak chemical weathering and were mainly derived from an immature source.
