Detrital record of mountain building : Provenance of Jurassic foreland basin to the Dabie Mountains [PDF]

, 2010
The Huangshi foreland basin developed on the southern margin of the Dabie Mountains as a result of tectonic loading during Triassic collisional suturing between the North China and South China cratons.

Organosulfur Aerosols Likely Carried Sulfur MIF Signatures in the Early Earth’s Atmosphere

Geochemistry, Geophysics, Geosystems, 2023
Signatures of mass‐independent fractionation (MIF) of sulfur in Archean sulfide and sulfate minerals are widely thought to record an anoxic early Earth’s atmosphere.

The continental record and the generation of continental crust [PDF]

, 2012
Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth's record of rock units and events is heterogeneous; for example, ages of igneous crystallization, metamorphism, continental margins, mineralization, and ...

Copper Isotope Fractionation in Archean Hydrothermal Systems: Evidence From the Mesoarchean Carlow Castle Cu‐Co‐Au Deposit

Geochemistry, Geophysics, Geosystems, 2023
Copper isotope analysis has emerged as a promising tool for understanding genetic processes in Cu ore deposits. However, applications of this analytical technique to Archean Cu deposits have been extremely limited, even though Archean terranes are among ...

Reservoir-forming rules and main controlling factors of Archean buried hill reservoir of middle to northern Liaoxi Uplift in Liaodong Bay area in Bohai Bay Basin

Shiyou shiyan dizhi
The Bohai Bay Basin is one of the key areas for the exploration of buried hill oil and gas resources in China. In order to create a new prospect for the exploration of the Archaean buried hills in this area, the reservoir-forming laws and main ...

Creating Continents: Archean Cratons Tell the Story [PDF]

, 2023
The record of the first two billion years of Earth’s history (the Archean) is notoriously incomplete, yet crust of this age is present on every continent.

Phonetic or morpholexical issues in L2 speech? A pilot study of ambiguity assessment for pedagogical purposes among Japanese learners of French

Language Testing in Asia
When second language (L2) learners speak in their L2, they can make errors involving one or several distinct linguistic levels (e.g., pronunciation errors, wrong lexical and morphosyntactic choices).

Water‐Induced Mantle Overturns Leading to the Origins of Archean Continents and Subcontinental Lithospheric Mantle

Geophysical Research Letters, 2023
The origins of Archean continents and subcontinental lithospheric mantle (SCLM) were important events in the early Earth. The mechanisms for the origins of Archean continents and the SCLM remain unclear.

Temporal and Hf isotope geochemical evolution of southern Finnish Lapland from 2.77 Ga to 1.76 Ga [PDF]

Bulletin of the Geological Society of Finland, 2012
The southern Finnish Lapland area in the central part of the Fennoscandian shield is a geologically complex zone comprising several Archean blocks and Paleoproterozoic supracrustal belts all of which are intruded by voluminous Paleoproterozoic granites ...
