李曙光院士：地幔组成的不均一性及其成因 - 知乎
网页尽管地幔的岩石种类和主要元素组成单一，但是大洋玄武岩的Sr、Nd、Pb 同位素调查发现，地幔的同位素组成是很不均一的。
Sr-Nd isotopic characteristics of the Northeast Sandy Land, …
网页2020年1月1日 · The Sr-Nd isotopic study of the Northeast Sandy Land (NESL), China is of great significance for a thorough understanding of the dust system in this area. The 162 bulk (<63 μm) and 86 size-fractioned samples of surface eolian sands and river sands in the NESL are very suitable to be added to the elaborate Sr-Nd isotopic composition dataset.

A database of radiogenic Sr–Nd isotopes at the “three poles”
网页2022年12月9日 · The isotopic compositions of the radiogenic elements strontium (Sr) and neodymium (Nd) are powerful tools for tracing dust sources and sinks because their characteristics vary significantly on the surface of the Earth (including snow, sand, sediment, loess, and eolian deposits) (Grousset et al., 1992; …
Sr–Nd isotopic geochemistry of Holocene sediments from the …
网页2018年2月20日 · Elemental geochemical and Sr–Nd isotopic signatures are used to decipher terrigenous sediments provenances and transport mechanisms in the South Yellow Sea during the Holocene. 87 Sr/ 86 Sr ratios in the Chinese and Korean riverine sediments overlap each other, whereas εNd values of Korean riverine sediments are generally less radiogenic in comp...
峨眉山玄武岩Sr、Nd、Pb同位素特征及其物源探讨
网页Abstract: Two most completely outcropped geological sections, Dadili of Yongsheng County and Shangcang of Binchuan County, Yunnan Province, are chosen for Sr, Nd and Pb isotopic geochemical study. Minor samples have the same Pb isotopic composition as C component defined by Hanan & Graham, whereas most of the samples are without C …
Sr and Nd Isotopes as Tracers of Chemical and Physical Erosion
网页2011年1月1日 · This review addressed the applications of Sr and Nd isotope systems for investigating contemporary and past chemical (silicate) and physical erosion in river basins, particularly those from the Himalaya.
Deciphering Contribution of Recycled Altered Oceanic Crust to Arc ...
网页2024年3月4日 · Key Points. Global arc data confirm that the Sr-Nd isotope decoupling of arc lavas is caused by AOC-derived fluid. Decoupled Sr-Nd isotopes plus heavy Ba isotope is a good tracer for recycled altered oceanic crust (AOC) in arc magmas. AOC and serpentinite show synergistic behaviors during subduction recycling.
呼伦贝尔沙地重矿物、Sr-Nd同位素组成及其对亚洲风尘系统的指示
网页为分析呼伦贝尔沙地的物质组成及探讨分选作用对重矿物和Sr-Nd同位素组成的影响，采集了呼伦贝尔沙地19个风成沙和河流沙样品，并进行了分粒级处理。
网页This dataset provides exhaustive detailed docu-mentation of the isotopic signatures at the three poles during specific time intervals in the Quaternary period, which are useful for understanding the sources or sinks of eolian dust and sediments at the three poles.
