近日,中国地质大学环境学院矿山环境保护与治理研究团队(周爱国教授、周建伟教授研究团队)在“锑矿区地下水环境砷锑污染”研究中取得新进展,相关成果发表在国际著名期刊《Journal of Hydrology》上,论文第一作者为中国地质大学地质调查研究院2014级博士生温冰。
近日,中国地质大学地质过程与矿产资源国家重点实验室赵来时教授团队在国际著名期刊《Geochimica et Cosmochimica Acta》发表题为Raman spectral, elemental, crystallinity, and oxygen-isotope variations in conodont apatite during diagenesis(牙形石磷灰石的拉曼光谱、元素...
We present the tellurium (Te) isotope compositions of the acid leachates and residues from three carbonaceous chondrites, namely, Allende, Murchison, and Tagish Lake. Most of the Te isotope compositi...
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea were determined. Wet decomposition was employed to oxidize relatively fresh orga...
We report the origin of significant fractionation of Pb isotope ratios in Ca-doped 0.08 mol L–1 HNO3 solutions. We applied Tl-spiked standard bracketing mass fractionation correction using solution-b...
Unlike most terrestrial rocks, some meteorites and their mineral components show isotope compositions that are clearly associated with nucleosynthetic processes in stars other than the Sun. Although ...
Terrestrial heat flow density, q, is inversely correlated with the age, t, of tectono-magmatic activity in the Earth's crust (Polyak and Smirnov, 1966; etc.). «Heat flow-age dependence» ind...
Os isotope compositions in ferromanganese crusts (Fe–Mn crusts) have been used for the dating of model ages from present to the Late Cretaceous. This dating method assumes that the Fe–Mn crusts prese...
Two piston cores (06GHSA P1 and 06GHSA P6) taken from the Ulleung Basin of the Japan Sea/East Sea were examined for the presence of an organic compound, diploptene (hopanoid 17α(H),21β(H)-hop-22(29)-...
We report high-resolution in situ Pb isotope analysis (207Pb/206Pb and 208Pb/206Pb ratios) by femtosecond laser ablation-multiple ion counter-inductively coupled plasma-mass spectrometry (fsLA-MIC-IC...
Characteristics of δ2 H and δ18O in precipitation samples collected at 16- to 17-d intervals at three stations at the northern end of Honshu Island, Japan, were investigated. Rokkasho and Ajigasawa ...
The Yangla copper deposit is located in western Yunnan Province, China, with an estimated Cu reserve of approximately 1.2 million tons. It is a typical giant copper deposit, and its mining started on...
δD and δ18O of natural waters with δ18O ranging from –24 to –6‰ were measured using a cavity ring-down spectroscopy (CRDS) in order to confirm that the CRDS method can be an alternative to convention...
Understanding the source and chemical characteristics of groundwater used for sake production is an important strategy for the quality management of sake brewing. Oxygen isotope ratios (δ18O) of 96 s...
The Namseong gold and silver deposit is located in the Seolcheon metallogenic province, one of the most important gold production areas in the Republic of Korea. It consists of three gold and silver-...
