Europe’s last Mesozoic bird [PDF]

, 2002
Birds known from more than isolated skeletal elements are rare in the fossil record, especially from the European Mesozoic. This paucity has hindered interpretations of avian evolution immediately prior to, and in the aftermath of, the Cretaceous ...

Structural deformation and geochronology of the ductile shear zone along the southern margin of the Foping dome, South Qinling

Dizhi lixue xuebao
Objective  A typical granulite–migmatite–gneiss dome developed in the Foping area of the central Qinling orogenic belt. This area is key to studying the metamorphic deformation of continental crust and the Mesozoic tectonic evolution of Qinling.

A Late Jurassic deep-bodied actinopterygian fish from Antarctica [PDF]

Acta Palaeontologica Polonica
Mesozoic deep-bodied actinopterygians are of interest given, among others, the various modes of feeding exhibited by these fishes. Regrettably, most of their fossil record is restricted to a limited number of localities in Europe.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin

Deep Underground Science and Engineering, EarlyView.
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Late Mesozoic mafic magmatism from the North China Block: constraints on chemical and isotopic heterogeneity of the subcontinental lithospheric mantle [PDF]

, 2005
Available major, trace element and Sr-Nd isotope data for the late Mesozoic mafic rocks in the eastern North China Block (NCB) show chemical and isotopic differences between rocks from different tectonic units.

Analysis of the formation conditions of Mesozoic secondary oil and gas reservoirs in Halahatang-Hade area of the Tabei Uplift

地质科技通报
Objective The Mesozoic strata in the Halahatang-Hade area of the Tabei Uplift belt, Tarim Basin, cover an area of more than 30 000 km2. It has a large monoclinic background, with active hydrocarbon displays and great exploration potential, but no ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...
