Black shales of the basal Lower Cambrian Niutitang Formation, southeast China, host a regionally distributed concordant, several centimeter-thick, sulfide layer which displays extreme metal enrichment, i.e., Mo-NiSe-Re-Os-As-Hg-Sb >1,000 times enriched and Ag-Au-Pt-Pd >100 over bulk continental crust. Mineable portions have about 5.5 wt percent Mo, 3.5 Ni, 1 g/t PGE + Au. A six-point 187 Os/ 188 Os versus Re/ isochron on molybdenum-nickel ore samples defines an age 541 ± 16 Ma (2σ) with...
Abstract Sedimentological and geochronological studies along a north–south traverse across the Bangong‐Nujiang suture zone ( BNSZ ) in Gaize, Tibet provide evidence for Late Triassic–Jurassic accretionary wedge accreted to south margin of Qiangtang. This wedge, preserved as Mugagangri Group MG ), records northward subduction Ocean BNO beneath The strata comprise two coarser intervals (lower olistostromes upper conglomerates) intercalated within sandy turbidites, which are consistent with...
Groundwater is a significant component of water resources, but drinking groundwater with excessive heavy metals (HMs) harmful to human health. Currently, quantitative source apportionment and probabilistic health risk assessment HMs in are relatively limited. In this study, 60 samples containing seven were collected from Hainan Island analyzed by the coupled absolute principal scores/multiple linear regression (APCS/MLR), (HRA) Monte Carlo simulation (MCS) quantify pollution sources risks....
Understanding the temporal and spatial distribution patterns of arc magmatism is crucial for interpreting evolution ancient crust formation because subduction a mature ocean basin involves multiple stages from initiation to collision, resulting in different kinds magmas overriding plate. A comprehensive compilation synthesis magmatism, combined with systematic studies key areas within relevant convergent margins, can effectively reveal specific processes, such as ridge initiation. The...
Understanding soil nutrient distributions and the factors affecting them are crucial for fertilizer management environmental protection in vulnerable ecological regions. Based on 555 samples collected 2012 Renshou County, located purple hilly area of Sichuan Basin, China, spatial variability total nitrogen (TN), phosphorus (TP) potassium (TK) was studied with geostatistical analysis relative roles were quantified using regression analysis. The means TN, TP TK contents 1.12, 0.82 9.64 g kg−1,...
Abstract Groundwater is an important source of water for human sustenance. The determination groundwater quality at island sites urgent priority in China, but there are lacking systematic reports relating to them. Here, 63 groups samples were collected and analyzed Hainan Island. the study area weakly alkaline, mainly comprising hard soft freshwater. predominant anions cations HCO 3 − , Ca 2+ Na + respectively, main chemistry types –Cl–Na –Cl–Na–Ca. chemical evolution affected by water–rock...
Monitoring and assessing coastal subsidence is crucial to mitigating potential disaster risks associated with rising sea levels. Nansha District in Guangzhou City, representing global soft-soil urban areas, faces significant challenges related ground subsidence. However, the current understanding of status, causative factors, risk (includes susceptibility vulnerability) assessment unclear. To address this gap, we utilized SBAS-InSAR technique, analyzing 49 Sentinel-1A images from December...
Although the innovation effects of carbon trading mechanism (CTM) have attracted considerable concern, there is still a lack empirical research on how CTM promotes efficiency green in China. Therefore, this paper purposes to investigate affects and revels its potential paths, including industrial structure, energy technological innovation, human capital, foreign direct investment (FDI), based panel data 30 provinces cities China spanning from 2008 2020. SBM-DEA model employed calculate...
The superimposed effects of sea level rise caused by global warming and land subsidence seriously threaten the sustainable development coastal cities. In recent years, an important city in China, Zhuhai, has been suffering from severe widespread subsidence; however, characteristics, triggers, vulnerability assessment ground Zhuhai are still unclear. Therefore, we used SBAS-InSAR technique to process 51 Sentinel-1A images monitor during period August 2016 June 2019. results showed that there...
