Contaminants that occur together naturally in groundwater under certain geological conditions may heighten health risks for millions of North Carolinians whose drinking water comes from private wells,...
Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U–Pb dating and Lu–Hf isotopes of detrital zircons from the Laoha River
North China Craton detrital zircon U–Pb age Hf isotope Laoha River
2017/4/11
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development
of ICP-MS technology, the U–Pb dating and Lu–Hf isotopic compositions of detr...
Dispersion of artificial caesium-134 and -137 in the western North Pacific one month after the Fukushima accident
Fukushima caesium western North Pacific zooplankton suspended solids
2017/4/11
In March 2011, an accident at the Fukushima Daiichi nuclear power plant (FNPP-AC) was caused by the Tohoku
earthquake and tsunami. Here we show the distribution of artificial caesium-134 and -137 (13...
Elemental and Sr–Nd isotopic compositions of Cenozoic sedimentary rocks from the Dongying Sag of Jiyang depression, North China: Implications for provenance evolution
provenance Dongying Sag Jiyang depression
2017/4/12
Major, trace element and Sr–Nd isotopic compositions of Cenozoic sedimentary rocks from the Dongying Sag and the
Zhanhua Sag, Jiyang Depression, provide evidence for provenance evolution and paleogeo...
Helium isotopes of seawater in the Philippine Sea and the western North Pacific
3He/4He ratios abyssal current Philippine Sea North Pacific seawater
2017/8/9
We measured helium isotopic ratios of 84 seawater samples from various depths collected in the western North Pacific Ocean and the western Philippine Sea. The 3He/4He ratios varied significantly from ...

A geochemical survey on thermal waters discharging in the Beas and Parvati valleys (Kulu District, Himachal Pradesh) and in the Sohna town (Gurgaon District, Haryana) was carried out in March 2002. Th...
Tectonic Implications of Some Cretaceous Pillow Basalts from the North Anatolian Ophiolitic Mélange(Central Anatolia-Turkey) to the Evolution of Neotethys
Seamount Geochemistry Callovian-Hauterivian Interval Tethys Ankara Mélange
2009/7/8
The most widespread blocks within the North Anatolian ophiolitic mélange of central Anatolia (Turkey) are ophiolitic fragments, Jurassic-Cretaceous carbonate blocks and pillow basalts. The blocks of ...
