The Altay orogenic belt of Xinjiang in NW China represents one of the important sites of juvenile crustal growth during the Phanerozoic. However, some important issues, e.g., tectonic evolution and petrogenesis, still remain controversial. The picrites in the south margin of the Altay orogenic belt ...

The Dabie Mountains are a collisional orogen between the South and North China blocks. The rock assemblages, isotopic dating and tectonic relationship of the tectonic-petrologic units in the eastern Dabie orogen indicate that the orogen is mainly composed of the different-grades metamorphic basement...

In Lingyuan region of West Liaoning Province, the Zhangjiakou Formation (J₃z) and the Yixian Formation (K₁y) display an angular unconformity. That is, the Lower Mesozoic strata of the Zhangjiakou Formation are ENE (near E-W) oriented, while the overlying strata of the Yixian Formation exhibit an NNE...

Neodymium (Nd) depleted mantle model ages indicate that the Kangding complexes in the northern segment of the western Yangtze craton, argued as representative of the craton's basement, actually formed after 1.6 Ga. An Sm-Nd isochron of 706 Ma constrains the upper limit formation of the complex from ...

Data obtained on conodont distribution in the Permian-Triassic Sovetashen Section of Transcaucasia provide further limitations on the age of the carbon-isotopic anomalies discovered by Baud et al. (1989). The significance of Caucasian sections for working out the carbon-isotope standard for the Uppe...

The Huize Pb-Zn deposits of Yunnan Province,located in the south-central part of the Sichuan-Yunnan-Guizhou (SYG) Pb-Zn multimetal mineralization district (MMD),are strictly controlled by fault zones. The sources of ore-forming fluid in the deposits have been debated for a long time. Calcite,a gangu...

Fort Munro Formation represents the products of the Upper Cretaceous (Maastrichtian) in the middle and lower Indus basins. The formation is exposed in the Rakhi Nala (Sulaiman Range), Bara Nala (Lakhi Range) and Naka Pabni (Southern Pab Range) areas. Major and trace elemental geochemistry and petrog...

Phosphorite has become increasingly important as the raw material for phosphatic fertilizer. Phosphorite nodules are widespread in the Kursk complex deposit (Russian platform). Genesis of these nodules has long been a matter of debate, and this has hampered understanding of the mechanism and control...

Determining the upper boundary of the cobalt-rich crust distribution of a guyot is important for estimating the mineral resources available, however, it has also long been an unsolved question. Correlations between the sub-bottom structures, revealed by sub-bottom profiling, and crust distribution c...

Drinking water is at risk from aniline pollution and thus aniline degradation and its mechanism have received much attention. In this paper, a soil column, including sediments and aquifer media, was collected from the Weihe riverbed and its bank, and used to research the characteristics of aniline d...
