Origin of the Dashuigou independent tellurium deposit at Qinghai–Xizang Plateau: constraints from the light stable isotopes C, O, and H
《Acta Geochimica》2024年第2期385-398,共14页Jianzhao Yin Yuhong Chao Haoyu Yin Hongyun Shi Shoupu Xiang 
Support for this study was received from Orient Resources Ltd.in Canada,Wuhan Institute of Technology,China,and College of Earth Sciences,Jilin University,China.
By studying the light isotopic compositions of carbon,oxygen,and hydrogen,combined with previous research results on the ore-forming source of the deposit,the authors try to uncover its metallogenic origin.The δ^(18)...

Evaluation of groundwater quality in the Dibdibba aquifer using hydrogeochemical and isotope techniques(Basrah Province,Iraq)
《Acta Geochimica》2022年第5期823-838,共16页Inass A.Al-Mallah Wasan S.Al-Qurnawi Hussein B.Ghalib Adnan B.Al Hawash Mariam H.Abdulameer 
The Dibdibba aquifer is considered to be the main source in the Al-Zubair area because agriculture depends on it to provide grazing water in the area.The groundwater well samples were collected from the shallow Dibdib...

The oceanic cycles of the transition metals and their isotopes
《Acta Geochimica》2017年第3期359-362,共4页Derek Vance Corey Archer Susan H.Little Michael Kobberich Gregory F.de Souza 
The stable isotope systems of the transition metals potentially provide constraints on the current and past operation of the biological pump,and on the state of ocean redox in Earth history.Here we focus on two exempl...
