Combined in situ U–Pb and Hf–O isotope analyses for zircon are often used to date igneous events precisely gain insights into the origin of magma from which crystallized. In conjunction with its resistance weathering, can therefore be considered a unique crystal toolbox an ideal crustal archive. This concept, however, relies on basic assumption that each is Hf equilibrium host magma. Here we test this hypothesis crystals mafic–ultramafic layered intrusions show may not always correct. We...
Forest canopy height is one of the most important spatial characteristics for forest resource inventories and ecosystem modeling. Light detection ranging (LiDAR) can be used to accurately detect surface terrain information from backscattering signals laser pulses, while photogrammetry tends depict envelope. The differences between surfaces estimated by LiDAR have not been investigated in depth. Thus, this study aims assess point clouds analyze heights. site located Jigongshan National Nature...
The Jinchuan Ni-Cu-PGE deposit is the single largest magmatic Ni-sulfide in world, with three different hypotheses on its ore-forming processes (e.g., in-situ sulfide segregation of sulfide-bearing magma, deep multiple injections and hydrothermal superimposition) mainly based study whole-rock geochemistry isotopes S-Sr-Nd-Hf). In this study, we concentrated magnetite textural geochemical characteristics from ores to clarify genetic types difference magnetite, explore a new credible process...
The Shangzhuang ultramafic intrusion in the Lajishan tectonic belt, South Qilian Belt, is mainly composed of serpentinite, biotite clinopyroxenite, apatite and hornblendite. Zircon grains selected from clinopyroxenite have distinctly oscillatory sector zoning yield a weighted average 206 Pb/ 238 U age 492.6 ± 4.1 Ma, which can be considered as crystallization intrusion. Initial 204 Pb 87 Sr/ 86 Sr ratios suggest an enriched mantle I source origin. Rocks Rb/Cs 16 to 29 Nb/U 0.2 11.7,...
Conventional ground survey data are very accurate, but expensive. Airborne lidar can reduce the costs and effort required to conduct large-scale forest surveys. It is critical improve biomass estimation evaluate carbon stock when we use data. Bayesian methods integrate prior information about unknown parameters, parameter uncertainty, model performance. This study focused on predicting independent tree aboveground (AGB) with a hierarchical using airborne LIDAR comparing classical (nonlinear...
Abstract The Neoproterozoic Bijigou intrusion is one of the largest and well-differentiated Fe–Ti oxide-bearing layered in Central China, hosts oxide ore layers middle zone with a total thickness ∼112 m. In order to examine role compaction compositional convection on solidification associated crystallization large amounts oxides, we collected samples from drill core profile apatite-oxide gabbronorite unit above main layer carried out detailed study crystal size distributions (CSDs) trace...
ABSTRACT Compaction is important to the expulsion and compositional modification of interstitial liquid crystal mush in solidification layered intrusions hosting Fe–Ti oxide mineralization. However, compaction manner evolution after onset abundant crystallization are still enigmatic. In this study, we collected samples from a drill core profile across major oxide-rich segment Bijigou intrusion, large differentiated intrusion Central China, carried out detailed study on late-stage magmatic...
The ~287 Ma Yejili mafic–ultramafic intrusion in the southern Alxa Block mainly consists of lherzolite, wehrlite, and gabbro. Rocks from lherzolite wehrlite have olivine with Fo values ranging 87.4 to 88.6 mol.% 81.6 mol.%, respectively, indicating crystallization a moderately evolved magma, that is mixing 5% 7% upper crust contaminant primitive magma modelling by Sr–Nd isotopic compositions. Samples generally low variable PGE (0.2 4.7 ppb) display trough‐like mantle‐normalized chalcophile...
Introduction Crown width (CW) is a significant variable of tree growth, but measuring crown laborious and time-consuming. Diameter at breast height (D) commonly used growth in prediction. Here, CW-D model was developed to estimate the larch. Methods The data 1,515 larch trees were collected Guandi mountain, northern China. We chose linear function, quadratic other form base functions develop CW models, we introduced non-linear least squares techniques (NLS), mixed-effect (NLME), Bayesian...
This study aimed to use CiteSpace software conduct a bibliometric analysis of published on the nursing informatics competencies from 2000 2020.
