Continental Crustal Growth Processes Recorded in the Gangdese Batholith, Southern Tibet

Di-Cheng Zhu et al.

Summary: The continental crust in the southern Tibet region of the India-Asia collision zone is characterized by an overthickened layer of felsic composition with an underlying granulite-eclogite layer. Extensive data suggests that this crust experienced magmatism from 245 to 10 million years ago, with flare-ups at 185-90 and 55 million years ago caused by a combination of external and internal factors. The growth of this crust is attributed to a process of fractional crystallization, subduction-induced melting, and collision-induced melting, resulting in vertical stratification and density sorting of the Gangdese crust.

Carbonatitic Magma Fractionation and Contamination Generate Rare Earth Element Enrichment and Mineralization in the Maoniuping Giant REE Deposit, SW China

Xu Zheng et al.

Summary: Carbonatite intrusions are important hosts for light rare earth element (LREE) deposits, and the processes of magma evolution and contamination from silicate rocks play a crucial role in the enrichment of REE. The study of the Maoniuping REE deposit in southwestern China provides insights into the magmatic evolution and REE enrichment through petrographic and geochemical analysis.

Eocene (∼ 53 Ma) alkaline complex in the southern Lhasa subterrane, Tibet: Implications for Neo-Tethyan slab breakoff

Xiaoshuang Chen et al.

Summary: This study presents a comprehensive investigation of the Mayum alkaline complex in the southern Lhasa subterrane, including whole-rock geochemistry, zircon U-Pb ages, and Sr-Nd-Hf isotopes. The results reveal that the alkaline rocks were generated through partial melting of the juvenile lower crust and experienced fractional crystallization. The associated mafic microgranular enclaves (MMEs) likely originated from a mantle source and underwent magma mixing with the host alkaline rocks. These findings provide insights into the timing and dynamic mechanism of the Neo-Tethyan oceanic slab breakoff at approximately 53 Ma.

Refertilized continental root controls the formation of the Mianning-Dechang carbonatite-associated rare-earth-element ore system

Zeng-Qian Hou et al.

Summary: Rare earth element ore deposits in southwestern China are associated with carbonatite derived from the mantle, but the formation of carbonatite and the processes of rare earth element enrichment and transport in the mantle are not yet fully understood. By combining seismic tomography with geochemical data, we have obtained images of the lithospheric structure of a Cenozoic rare earth element ore belt in southwestern China. The subduction of the Indian continent led to vertical upwelling and lateral flow of the asthenosphere, triggering melting of the overlying subcontinental lithospheric mantle and the formation of carbonatite. This metasomatism of the mantle, previously influenced by fluids from recycled marine sediments, is a critical precursor process for the formation of giant rare earth element systems. The key factors for the formation of the studied ore belt include a thick lithosphere with a continental root, prior rare earth element enrichment of the subcontinental lithospheric mantle, and a weak pathway for magma ascent.

Formation of the Maoniuping giant REE deposit: Constraints from mineralogy and in situ bastnasite U-Pb geochronology

Qiang Weng et al.

Summary: This study investigates the time and processes of hydrothermal mineralization using the Maoniuping giant rare earth elements deposit as a case study. The results show that rare earth minerals occur in different forms, with one originating from magmatic processes and others from hydrothermal processes. The mineral compositions and isotopic dating suggest a continuous magmatic-hydrothermal evolution for the rare earth mineralization in the Maoniuping alkaline complex.

Formation of Rare Earth Deposits in Carbonatites

Michael Anenburg et al.

Summary: Carbonatites and related rocks are the primary source for light rare earth element (LREE) deposits, where LREEs strongly partition to carbonatite melts, forming primary alkali REE carbonates. These primary carbonates are rarely preserved and are usually dissolved by later fluids, being replaced by other minerals like monazite and alkali-free REE-(fluor) carbonates.

Mineralogical characteristics and Sr-Nd-Pb isotopic compositions of banded REE ores in the Bayan Obo deposit, Inner Mongolia, China: Implications for their formation and origin

Zuoyu Gao et al.

Summary: The study investigated the mineral assemblages and geochemical characteristics of minerals in banded ores in the Bayan Obo REE deposit, revealing that the REE minerals were mainly monazite, bastna site, and parisite. The overprinting of these minerals on gangue minerals suggests REE mineralization occurred in the late hydrothermal stage, leading to progressive enrichment in REEs, F, Sr, and Ba. Additionally, the study proposed that fluorite and bastna site crystallized from ferrocarbonatite and fine-grained dolomite, with a mixture of HIMU mantle and global marine sediments serving as the source of REEs.

Non-matrix-matched analysis of U-Th-Pb geochronology of bastnasite by laser ablation inductively coupled plasma mass spectrometry

Tao Luo et al.

Summary: Bastnasite is commonly found in different types of rock formations, and its U-Th-Pb ages can indicate the age of mineralization. The lack of suitable in situ analysis reference material is currently a major challenge for bastnasite U-Th-Pb geochronology. This study used glass NIST 610 as an external calibration reference to evaluate the matrix effects in determining U-Pb and Th-Pb ages in bastnasite, and found that with the addition of water vapor, accurate and precise U-Th-Pb ages of bastnasite can be obtained using LA-ICP-MS analysis.

The effect of fluid-aided modification on the Sm-Nd and Th-Pb geochronology of monazite and bastnasite: Implication for resolving complex isotopic age data in REE ore systems

Xiao-Chun Li et al.

Summary: Isotopic dating studies on the Bayan Obo REE deposit in China show that fluid-assisted modification of monazite and bastnasite results in varied Th-Pb ages, with some representing partial isotopic resetting. The study also suggests resistance of Sm-Nd isotopes but susceptibility of Th-(U)-Pb isotopes to fluid-aided modification, cautioning against younger Th-U-Pb dates in geologically complicated deposits.

Carbonatites and Alkaline Igneous Rocks in Post-Collisional Settings: Storehouses of Rare Earth Elements

Kathryn M. Goodenough et al.

Summary: The rare earth elements (REE) are crucial for modern technology, especially for renewable energy infrastructure and electric vehicles. The paper reviews REE mineralisation in post-collisional alkaline-carbonatite complexes worldwide, highlighting key physical and chemical features of these deposits. Immiscibility of carbonate-rich magmas and fluids is shown to play a significant role in generating mineralisation, with REE, Ba and F partitioning into the carbonate-rich phase.

Summary: The Sr-rich carbonatites reported in Mianning County, Sichuan Province have unique microcrystalline to porphyritic textures and a rich mineral assemblage, indicating a special origin related to shallow emplacement and magmatic evolution. The presence of quartz phenocrysts and high-quality ore minerals suggests a significant potential in mineral resources for this type of carbonatite.
