Age and Geochemistry of High Arctic Large Igneous Province Tholeiitic Magmatism in NW Axel Heiberg Island, Canada by F. M. Deegan, V. Pease, I. G. Nobre Silva, J. H. Bédard, G. Morris

“…Most samples, however, possess relatively radiogenic isotope signatures that can be explained by moderate degrees of assimilation of Sverdrup Basin sedimentary rocks. Magma‐crust interaction in the HALIP plumbing system was likely widespread and may have increased the environmental impact of the HALIP, particularly if crustal carbon was volatilized.…”

The Mechanisms Forming the Five–Floor Zonation of Quartz Veins: A Case Study in the Piaotang Tungsten–Tin Deposit, Southern China by Xiangchong Liu, Wenlei Wang, Dehui Zhang

“…Their vertical changes indicate that the fractures that bear the thick veins were well connected, facilitating fluid focusing and mineralization in mechanically stronger host rocks. Three generations (Q1–Q3) of quartz were identified from CL images, and the CL intensity of quartz is possibly controlled by the concentrations of Al and temperature. …”

Geochemistry of marine black shale of the Cambrian Qiongzhusi Formation, Yangtze Plate, SW China: implications for provenance and paleoweathering by Zexin Fang, Ling Guo, Jianni Liu

“…The ratios of w(SiO2)/w(Al2O3) and w(Al2O3)/w(TiO2), the Zr-TiO2 diagram, the Th/Sc vs Zr/Sc plot, the discriminant function of F1 vs F2 and F3 vs F4, as well as the discrimination diagram of âREE vs La/Yb indicated that the main provenances of QZS shale are sedimentary and felsic igneous rocks. The values of a chemical weathering index, the chemical index of alteration (CIA), of the Lower QZS Formation (Stage 1) range from 51.84 to 64.33, indicating a low degree of chemical weathering and a cold and dry climate. …”

MICROELEMENT AND STABLE ISOTOPIC COMPOSITION OF SNOWPACK IN THE KATUNSKY BIOSPHERE RESERVE (ALTAI REPUBLIC) by T. S. Papina, A. N. Eirikh, N. S. Malygina, S. S. Eyrikh, O. V. Ostanin, T. V. Yashina

“…The analysis of microelement composition of the snow samples made with the use of the crustal enrichment factor (EFc) and correlation matrix allowed determination of elements (Ba, Be, V, Co, Li, Mn, Ni, Sr, Tl, Th, U и Cs) released into the atmosphere above the territory under investigation mainly with particles of fly ash, in which the ratio of elements corresponds to the regional natural sources – soils and underlying rocks. It was shown that the main part of elements Ag, As, Bi, Cu, Mo, Sb, Zn come preferably from anthropogenic sources which are non-ferrous metallurgy enterprises of East Kazakhstan and pits of operating and abandoned mines of Rudny Altai.…”
