In this study, we identify redox-related Hg post-depositional processes and associated magnitudes in an open (tree-less) boreal peatland system, Degerö Stormyr (64°11’N, 19°33’E, Supplementary Fig.S1). We have comprehensively investigated the uppermost meter of14C dated peat soil by co...
The gold mineral systems of the West Qinling orogen, central China: New insight from the Baguamiao gold deposit 2023, Ore Geology Reviews Citation Excerpt : Currently, more than 100 sediment-hosted gold deposits with an estimated gold resource of over 2, 000 tons, have been discovered. As suc...
D–O isotopes have been believed to be an efficient tool to trace the recharge source of water resource [17,18,19], while Sr isotope is able to identify the rock type of aquifers [20,21,22]. Water resources, including groundwater and surface water, are abundant in the Longzi county, ...
The paper presents a quantification of main (hydrogen sulfide and sulfate), as well as of intermediate sulfur species (zero-valent sulfur (ZVS), thiosulfate, sulfite, thiocyanate) in the Yellowstone National Park (YNP) hydrothermal springs and pools. We
Variations among isotopes of a given element occur below this value, but get reduced with an increasing atomic number. For instance, at 0.25 MeV/u, while 2H deposits 2.78-times higher energy to the cell nucleus than protons do, between 12C and 11C this ratio is just 1.16. Figure 2. ...
Table 1. Location and description of the studied intrusive rocks in the Tuwu-Yandong belt. 3.2. Analytical Methods The ten least altered samples were selected for whole-rock major and trace element as well as Sr–Nd isotopic analyses. Three samples were chosen for LA–ICP–MS zircon U–Pb...
All data underwent ZAF correction, achieving an accuracy better than ±0.5 wt%. 3.2. Major- and Trace-Element Geochemistry Eleven rock samples were collected from the surface exploratory trenches and the surrounding rocks of the TCG-11 ore body within the Saima Deposit. Samples SMK-1 through ...
3.2. Whole Rock Major and Trace Element Analyses The major and trace element analysis for the bulk rock samples was mainly carried out in the Yanduzhongshi Geological Analysis Laboratories Ltd. (103 Beiqing Road, Haidian District, Beijing). First, fresh samples were broken to centimeter sizes; ...
Moreover, faults have the potential to exert a profound impact on the hydrodynamics of aquifers, as well as the hydrochemistry of the system. Consequently, such influence can result in alterations to the flow regimes within an aquifer and ultimately affect the observed salinity levels within the ...
Further, the DCG contains a large amount of geologic information from an era prior to the Mesoproterozoic. Therefore, the DCG can be regarded as an ideal unite for studying the growth and evolution of Proterozoic and Archean crustal of the Yangtze Block. Zircons have a strong ability to resist...
