Abstract Plumbogaidonnayite, ideally PbZrSi 3 O 9 ⋅2H 2 O, is a new gaidonnayite-group mineral discovered as secondary product derived from the alteration of eudialyte Saima alkaline complex, China. It occurs aggregates (up to 1 mm) composed subhedral anhedral or platy crystals (individually 5–50 μm), associated closely with microcline, natrolite, aegirine, gaidonnayite, georgechaoite, zircon, bobtraillite and britholite-(Ce) in pseudomorphs. The are transparent, colourless light brown...
The Huanglongpu deposit is one of the most representative igneous carbonatite-type molybdenum-rare earth element (Mo-REE) deposits in eastern Qinling metallogenic region. molybdenum resources exceed 180 kt, whilst total rare are about 37.8 kt. However, age REE mineralization, sources ore-forming minerals, and tectonic setting not well characterized. Therefore, this study carried out detailed mineralogical, geochronological, geochemical analyses to provide new insights. Monazite, bastnäsite,...
Abstract. Middle–Late Jurassic high-Sr/Y granitic intrusions are extensively exposed in the Liaodong Peninsula eastern part of North China Craton (NCC). However, genesis high Sr/Y signature these has not been studied detail. In this study, we report results zircon U–Pb dating, Hf isotopic analysis, and whole-rock geochemical data for Late Zhoujiapuzi granite middle Peninsula. The is high-K (calc–alkaline) peraluminous nature, with SiO2 (68.1 wt %–73.0 %) Al2O3 (14.5 %–16.8 %), low TFe2O3...
The Huayangchuan U-polymetallic deposit in the Qinling Orogen is a newly verified carbonatite-hosted on southern margin of North China Craton (NCC) Central China. Granitic magmatism extensively developed area and lacking analysis reasons for these situations; however, its ages, petrogenesis, relationship with uranium mineralization are not well constrained. Zircon U–Pb ages hornblende-bearing granite porphyry medium-fine-grained biotite granites close proximity to carbonatite rocks 229.8 ±...
Abstract Fluorsigaiite, ideally Ca 2 Sr 3 (PO 4 ) F, is a new analogue of fluorphosphohedyphane and member the apatite supergroup. It was discovered in lujavrite from Saima alkaline complex, Liaoning Province, China. Fluorsigaiite commonly occurs as individual prismatic, columnar platy crystals 10 to 50 μm size, associated with microcline, nepheline, aegirine, natrolite, eudialyte, fluorapatite, fluorstrophite-like mineral, stronadelphite calcite. Occasionally, fluorsigaiite form prismatic...
Abstract The new mineral, gysinite-(La), with the ideal formula PbLa(CO 3 ) 2 (OH)⋅H O, has been discovered in lujavrite from Saima alkaline complex, Liaoning Province, China. It commonly occurs as subhedral to anhedral, granular and platy crystals of 5 50 μm size, interstices or enclosed microcline, aegirine nepheline. Associated minerals include nepheline, aegirine, natrolite, eudialyte, lamprophyllite, bastnäsite-(Ce), parasite-(Ce), ancylite-(La), ancylite-(Ce), bobtraillite,...
Abstract The Ganjiang River, one of eight major tributaries the Yangtze located in western hinterland Cathaysia Block, SE China, has a length 823 km and drainage area 82 809 2 , whose detrital zircons provide valuable means to trace sediment provenances river explore crustal growth evolution Block. In current study, 389 concordia zircon U–Pb age spots rare earth element (REE) contents, combination with 201 Lu–Hf isotope analyses, have been determined. Oscillatory zoning, high Th/U ratios REE...

Based on acoustic finite element method, numerical simulations are established in this paper to study the incident sound transmission loss (STL) of constrained layer damping (CLD) structure. The influence and mechanism viscoelastic insulation performance CLD structure studied simulations. Firstly, through constitutive model theory material, material is implemented. Then, simulation models composite linear elastic established. STL, displacement amplitude phase compared analyzed. Results show...
