Lithium–strontium isotope and heavy metal content of fluid inclusions and origin of ore-forming fluid responsible for tungsten mineralization at Takatori mine, Japan
fluid inclusion lithium isotope initial 87Sr/86Sr ratio Takatori mine tungsten mineralization
2017/4/11
Ore-forming fluid trapped in vein quartz as fluid inclusions from tungsten ore at the Takatori mine was extracted by a
crush-leach technique. The trace metal content and isotopic composition (δ7Li an...
A normalised seawater strontium isotope curve and the Neoproterozoic-Cambrian chemical weathering event
normalised seawater strontium isotope curve chemical weathering event
2009/10/22
The strontium isotope composition of seawater has varied over geological time in response to changes in the rates of continental weathering relative to ocean crust alteration. However, the potential o...
Strontium Isotopic and Micropalaeontological Dating Used to Help Redefine the Stratigraphy of the Neotectonic Hatay Graben, Southern Turkey
Cenozoic stratigraphy strontium isotopes micropalaeontology Hatay Graben Karasu Rift Dead Sea Fault Zone Eastern Mediterranean
2009/7/7
In this paper we report for the Hatay Graben, new micropalaeotology, the first strontium dating and new sedimentology. The previous lack of a modern systematic stratigraphy was problematic for the st...
Strontium isotopic and elemental characteristics of calcites in the eolian dust profile of the Chinese Loess Plateau during the past 7 Ma
Chinese Loess Plateau the eolian dust profile strontium isotope of calcite chemical weathering the East Asian summer monsoon
2017/8/10
Strontium isotopic ratios, calcium and strontium contents of calcites in the eolian dust profile during the last 7 Ma at Lingtai were systematically studied. 87Sr/86Sr ratios of calcites change with t...
An Aluminum Pillared Montmorillonite with Fast Uptake of Strontium and Cesium from Aqueous Solutions
Cation Exchange Capacity Delamination Pillared Clay Radiocesium Radiostrontium Uptake
2011/12/22
Abstract: The uptake of Sr and Cs by 2 types of aluminum pillared layered clays (Al-PILC), a reference sample (AZA) and a specially tailored sample (FRAZA), were investigated. The AZA sample was prepa...
Hydrothermal Reactions of Strontium and Transuranic Simulator Elements with Clay Minerals, Zeolites, and Shales

2012/2/6
Reactions of Sr, La, and Nd (the latter two elements simulating Am and Cm) with potential backfill minerals for radioactive waste storage and with repository wall rocks, such as shale, were investigat...
The Location of Iron-55, Strontium-85 and Iodide-125 Sorbed by Kaolinite and Dickite Particles
Location of Iron-55 Strontium-85 Kaolinite Dickite Particles
2012/2/15
The autoradiographic method at the electron microscope level has been applied successfully to locate the position of sorbed ions and compounds associated with kaolinite and dickite particles. For suit...
