Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Holocene climate oscillations, seismotectonic events and human–environmental interactions reconstructed from the Giannades palaeolake on Corfu (Eastern Mediterranean, Greece)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Mediterranean is particularly sensitive to rapid climate changes (RCCs) during the Holocene. An increasing number of natural climate archives revealed that socio‐economic developments were influenced by such RCCs since the Palaeolithic. However, multi‐millennial and high‐resolution archives are still rare and often located in mountainous ...

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...
