Lithium Isotope Fractionation during Granitic Magma Differentiation: Insights from Whole Rock and Mineral Analyses Open
Despite extensive studies on whole-rock lithium (Li) isotope geochemistry, the fractionation of Li isotopes among minerals in granitic magmatic systems is still poorly understood. To investigate the magnitude and mechanism of inter-mineral…

Mineralizations of Nb-Ta-Rb-Zr and rare-earth elements in Boziguoer, South Tianshan, NW China: Geochronology and geochemistry of monazite and bastnäsite Open
The Boziguoer alkaline intrusion is located in the South Tianshan Orogenic Belt on the northern margin of the Tarim Craton. The intrusion is entirely mineralized and forms a super-large rare metal (RM) and rare-earth element (REE) deposit …

K isotopic fractionation in K-feldspar: Effects of mineral chemistry Open
Controlling factors of potassium (K) isotopic fractionation in K-feldspar remain poorly constrained. In this study, we analyzed the K isotopic compositions of 11 K-feldspar samples from diverse lithological compositions. The degree of Al/S…

Paleomagnetism of the ~860 Ma Manso dyke swarm, West Africa: implications for the assembly of Rodinia Open
<p>The West African Craton (WAC) is one of the major cratons in the Rodinia jigsaw puzzle (~1000&#8211;750 Ma). In the Rodinian models, the position of West Africa is mainly constrained by the assumption that it had been a partne…

Polyphase tectonothermal events recorded in metamorphic basement rocks from the northern Altyn Tagh, southeastern Tarim Craton Open
<p>&#160; Paleoproterozoic is a pivotal time for understanding the geochronological framework of the Tarim Craton. Located on the southeastern margin of the Tarim Craton, the northern Altyn Tagh is the main exposed region for Pal…

Platinum-Group Mineral Occurrences and Platinum-Group Elemental Geochemistry of the Xiadong Alaskan-Type Complex in the Southern Central Asian Orogenic Belt Open
Alaskan-type complexes commonly contain primary platinum-group element (PGE) alloys and lack base-metal sulfides in their dunite and chromite-bearing rocks. They could therefore host PGE deposits with rare sulfide mineralization. A detaile…

Origin of Reverse Zoned Cr-Spinels from the Paleoproterozoic Yanmenguan Mafic–Ultramafic Complex in the North China Craton Open
We conducted petrological and mineral chemistry investigations of Cr-spinel in ultramafic rocks of the Yanmenguan mafic–ultramafic complex in the North China Craton. The Cr-spinel grains occur as inclusions in enstatite, tschermakite, phlo…

Paleozoic subduction-related magmatism in the Duobagou area, Dunhuang block: Constrained by zircon U-Pb geochronology and Lu-Hf isotopes and whole-rock geochemistry of metaigneous rocks Open
The Dunhuang block, situated at the junction of the Tethyan domain, Tarim craton, North China craton and the Central Asian Orogenic Belt (CAOB), consists mainly of Archean–early Mesoproterozoic basement rocks and Paleozoic metamorphic and …
