Abstract The morphologically differentiated benthic macrofossils of algae and putative animal affinities the Lantian biota in China represents oldest known Ediacaran macroscopic eukaryotic assemblage. Although provides remarkable insights into early evolution complex macroeukaryotes Ediacaran, uncertainty its age has hampered any robust biological evaluation. We resolve this issue by applying a petrographic-guided rhenium-osmium (Re-Os) organic-bearing sedimentary unit study on biota. This...
The magmatic-hydrothermal evolution of porphyry-style mineralization in the shallow crust that is linked to magmatic processes at depth has been extensively studied using bulk-sample isotopic analysis combined with relative timing constraints. However, a lack evaluation fluid process against an absolute time frame limits further understanding ore-forming process. Here, we quantify within for first by integrating new situ oxygen isotope data from Qulong porphyry Cu-Mo deposit (Tibet) existing...
A new ideal zircon microanalytical reference material (Tanz) is presented for in situ U–Pb, O and Zr isotope measurements.
Abstract Fertility and longevity of hydrothermal systems are key parameters required to improve our ability in predicting new deposits directly extracting metals from metalliferous fluids. Reconstructing evolutional trajectories fluids with high temporal resolution is critical for pushing understanding forward, but this inevitably challenging because traditional approaches obtaining information either have poor and/or bear considerable uncertainties. We present a novel approach (translating...
First, test the water! In presence of a chiral Lewis base catalyst 2, supposedly moisture-unfriendly reduction system with trichlorosilane was found to be highly efficient and enantioselective when using water as an additive. For first time, this method enables broad range N-alkyl β-enamino esters 1 give β-amino 3 in good high yields excellent enantioselectivities (see scheme).

Abstract. Conventional Re–Os isochrons are based on mass spectrometric estimates of 187Re/188Os and 187Os/188Os, which often exhibit strong error correlations that may obscure potentially important geological complexity. Using an approach is widely accepted in 40Ar/39Ar U–Pb geochronology, we here show these greatly reduced by applying a simple change variables, using 187Os as common denominator. Plotting 188Os/187Os vs. 187Re/187Os produces “inverse isochron”, defining binary mixing line...
ABSTRACT The Chinese Bayan Obo deposit is a world-class rare earth element (REE) with considerable niobium (Nb) and iron (Fe) resources. A complete genetic understanding on all metals fundamental for establishing models at Obo. With extensive research being focused REE enrichment, the timing controls of Nb enrichment remain unresolved Obo, which mainly due to challenges in dating, i.e. multistage thermal events, fine-grained minerals complex textures occurrence uranium-enriched mature dating...

Abstract With the continuous advancement and maturation of technologies such as big data, artificial intelligence, virtual reality, robotics, human-machine collaboration, augmented many enterprises are finding new avenues for digital transformation intelligent upgrading. Industry 5.0, a further extension development 4.0, has become an important trend in industry with more emphasis on human-centered sustainability flexibility. Accordingly, both industrial metaverse twins have attracted much...
Bastnaesite, a common accessory mineral in REE ore deposits, is ideal for U–Pb isotopic dating because of its relatively high U and Th contents.
