To investigate the effects of rainfall on river water quality in a mixed-industrial-agricultural urban area and to analyze sources pollution, this study focused Jianjiang River, primary tributary western reaches Pearl River system. impact an with mixed industrial agricultural activities, six monitoring sections along Maoming segment three meteorological stations, were chosen as research sites. Utilizing box-and-whisker plots, correlation analysis, absolute principal component-multiple...
The origin and petrogenesis of pegmatite-type lithium deposits within the Songpan-Garze Fold Belt (SGFB) western China remain subjects debate. To provide further insight on this subject, study investigated whole-rock trace elements Li isotopic compositions two-mica monzogranite (TMG) from Ke'eryin composite pluton, Jiada albite pegmatite (AP) albite-spodumene (ASP) their metasedimentary wall rocks ore field in eastern SGFB. Modeling muscovite-dehydration melting based (e.g., Li, Rb, Sr)...
Since 2012, some advances have been made through the resource investigation, metallogenesis research, and comprehensive utilizing of lithium deposits in China. Firstly, progress exploration has Sichuan, Xinjiang, Qinghai Jiangxi provinces (autonomous region). Li are not only found within pegmatite rocks but also granitic sedimentary rocks. Secondly, methods geological survey, geochemical geophysical exploration, remote sensing technology even drilling improved, which can be delineating...
Most Copper (Cu) and Gold (Au) deposits are accompanied by hydrothermal alteration, generally related to ore-forming fluids. Multispectral hyper-spectral Remote Sensing (RS) technology is essential for Cu-Au mineral prospecting. This paper provides an overview of RS data the research situation development tendencies exploration technologies deposits. Initially, geologists applied Band Ratio (BR) Principal Component Analysis (PCA) extract hydroxyl iron anomalies from Landsat characterize...
Phosphorus is the primary contributor to eutrophication in water bodies, and identifying phosphorus sources rivers crucial for controlling pollution subsequent eutrophication. Although phosphate oxygen isotopes (δ18OP) have capacity trace cycling sediments, they not been used small- medium-sized watersheds, such as Xiaodongjiang River (XDJ), which located an agricultural watershed, source–complex region of southern China. This study employed isotope techniques combination with a...
华南陆块中生代受古特提斯构造域和滨太平洋构造域两大动力学体系控制，形成了独具特色的华南大花岗岩区和巨量稀有金属富集的成矿省。在印支期-燕山期动力体制转换的背景下，华南陆块内同一构造单元经历了不同世代、不同源区、多个类型岩浆作用相关的矿床成矿（亚）系列的叠加和演化，其叠加成矿机理是华南中生代大规模成矿作用研究的关键，其复合成矿效应是华南各成矿区带找矿预测工作的重要依据。本文结合近年来华南稀有金属矿产勘查、矿床学研究和深部探测工作的新进展，构筑了华南钨锡锂铍铌钽和风化壳型稀土矿床的时空谱系，对比了相关花岗岩的成矿专属性及其成岩构造环境。明确提出了矿床成矿系列叠加的三种形式，即同构造单元，不同世代岩浆作用相关的同类矿床成矿（亚）系列的叠加，其成矿源区和成矿物质可能具有一定继承性；二是同构造单元或构造岩浆带结合部，同时期不同类矿床成矿（亚）系列的复合成矿；三是同构造单元或构造岩浆带结合部，不同时期构造岩浆事件、不同源区、不同类型矿床成矿（亚）系列的叠加。矿床成矿系列叠加显著提升了区域成矿强度，且多发生于深部构造长期活动区，不同时期的同类矿床成矿亚系列常具有一定继承演化关系。本文进一步探讨...
Saline soils are of great concern globally. Selecting the Yellow River Delta as a model site, influence reclamation on soil salinity and saline quality was investigated. Soil index (SQI) applied to statistically analyze 210 profile samples collected at seven depth layers in 30 sampling sites among native three croplands (peanut, cotton, wheat) May 2020. After reclamation, salt content (SSC) reduced from 4.52 g/kg 1.44 after with degree reducing severe slight. The nitrate nitrogen (NO3−-N)...
The Ke'eryin ore field in the Songpan-Garze Fold Belt (SGFB), western China, is an important area of pegmatite-type lithium accumulation. However, petrogenesis pegmatites and their genetic relationships with neighboring granitic pluton are still a topic debate. In this work, LA-MC-ICP-MS zircon columbite-tantalite U-Pb dating, whole-rock mica geochemical analysis, isotopic analysis newly discovered Jiada deposit were performed. Zircon dating biotite K-feldspar granite (BG), fine-grained...
AbstractVoluminous Neoproterozoic granitoid sheets of the Imorona–Itsindro Suite are important components exposed basement in west-central Madagascar. Here, we report precise new zircon U–Pb ages and whole-rock geochemistry for granitoids within Maevatanana area The laser ablation inductively coupled plasma mass spectrometry dating undertaken during this study indicates that Antanimbary Antasakoamamy were emplaced at 747 ± 9 Ma 729 9–727 8 Ma, respectively. Geochemically, show poor Nb, Ta...
Large-scale afforestation poses threats to water resources security in water-limited areas, and the availability affects plants growth mortality. Shelterbelts degradation inevitably causes stand structure changes, which affect soil content (SWC). In this study, we used high-density sampling method study Populus simonii Carr stands located only 6.3 km2 Boluosu forest farm semiarid region of northern China, including healthy degraded stands, cropland grassland plots as controls. The vertical...
Previous studies on the Ke’eryin pegmatite-type lithium ore field in Songpan–Ganzi Orogenic Belt have explored characteristics of parent rock but not precisely determined its magma source area. This uncertainty limits our understanding regularity formation this region. In study, to address issue precise area mineralization, a detailed analysis Li isotope composition ore-forming (Ke’eryin two-mica monzogranite) and potential rocks (Triassic Xikang Group metamorphic rocks) was conducted. The...
The saline soils in the Yellow River Delta are primarily affected by seawater intrusion resulting from intersection of land and sea, which exhibit variations salinity. quality these is also influenced anthropogenic reclamation, including fertilization irrigation. This study quantitatively evaluated distinct soil properties characteristics during different reclamation years (i.e., 0a, 1a, 5a, 10a, 20a) using principal component analysis (PCA) Soil Quality Index (SQI). findings indicated that...
