Genesis and magma fertility of gold associated high-K granites:LA-ICP-MS zircon trace element and REEs constraint from Bakoshi–Gadanya granites in NW Nigeria
《Acta Geochimica》2022年第3期351-366,共16页Safiyanu Muhammad Elatikpo Huan Li Yuanlin Chen Hafizullah Abba Ahmed 
co-financed by the National Natural Science Foundation of China (Grant No.41502067);the Science and Technology Innovation Program of Hunan Province (Grant No.2021RC4055)。
High-K granites dominate the rock units in the Bakoshi and Gadanya areas located in the northwestern Nigerian subshield,part of the Trans-Saharan Belt,West Africa.In this contribution,the LA-ICP-MS zircon trace elemen...

Fractionation characteristics of rare earth elements(REEs) linked with secondary Fe, Mn, and Al minerals in soils被引量：6
《Acta Geochimica》2016年第4期329-339,共11页Chunying Chang Fangbai Li Chengshuai Liu Jianfeng Gao Hui Tong Manjia Chen 
funded by the National Natural Science Foundation of China(41420104007,41330857,and 41673135);the Guangdong Natural Science Foundation of China(S2013050014266);the One Hundred Talents Programme of The Chinese Academy of Sciences
Soil secondary minerals are important scavengers of rare earth elements(REEs) in soils and thus affect geochemical behavior and occurrence of REEs. The fractionation of REEs is a common geochemical phenomenon in soils...
