Isotopic Composition of Strontium in Carbonatites [PDF]

Nature, 1964
BAILEY has inferred that Hamilton and Deans1 have agreed with Powell et al.2 that investigations of strontium isotopes show that the source of carbonatites is exclusively from below the sial. At present the isotopic composition of strontium has been examined in well-documented carbonatites and the results clearly show that they have been derived from a

Galgedil

Danish Journal of Archaeology, 2014
Galgedil is a Viking Age cemetery located in the northern part of the Danish island of Funen. Excavations at the site revealed 54 graves containing 59 inhumations and 2 cremation burials. Previous study of the remains to date has included light isotopes

Understanding intra-individual isotopic variability in modern cremated human remains for forensic and archaeological studies.

PLoS ONE
Cremated bone fragments can be studied using structural, elemental, and isotope analyses in archaeological contexts to reconstruct funerary practices and understand past mobility and migrations of populations that practiced cremation.

Testing the 87Sr/86Sr isotopic ratio measured by ICP-MS as a tracer for inter-well investigation in oil reservoirs

EPJ Web of Conferences, 2013
The use of the 87Sr/86Sr isotope ratio has been tested as a natural tracer for inter-well tests in oil reservoirs using standard mass-spectrometry equipment. Such an application can have a special interest to offshore oil fields.

Fluid-driven element mobility resets plagioclase rubidium strontium and barium clocks while potassium feldspar resists

Communications Earth & Environment
Rubidium, cesium, strontium, barium and their isotopes are employed as tracers of magmatic differentiation and fluid-mediated metasomatism, but their mobility during mineral-scale alteration remains uncertain.

New Isotopes of Strontium and Barium [PDF]

Nature, 1931
APPLICATION of high resolution to accelerated anode rays has now provided improved mass-spectra of these two elements. Strontium shows a third isotope 87 in addition to those already observed. Results with barium were only obtained with great difficulty.

Shielding Calculation of Isotope Battery Based on cosRMC

Yuanzineng kexue jishu
As a new type of energy system, thermoelectric isotope battery system is widely used in deep space and deep sea exploration missions. Strontium titanate fuel is used as the heat source for thermoelectric isotope batteries.

Relative dating of deposits of the Mishan Formation based on foraminifera and Strontium isotope in northwest and west of Bandar Abbas, south Iran [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2016
For studying of biostratigraphy of Mishan Formation in Bandar Abbas hinterland, a stratigraphic transection including Handun, Anguru, Baviyun, and Nakh sections was selected in northwest and west of Bandar Abbas.

Application of hydrochemistry and strontium isotope for understanding the hydrochemical characteristics and genesis of strontium-rich groundwater in karst area, Gongcheng County, Southwest China

Journal of Groundwater Science and Engineering
Understanding the hydrochemical characteristics and genesis mechanisms of strontium-rich groundwater is pivotal for supporting the exploitation and utilization of natural strontium-rich groundwater. In this research, 27 groundwater samples were collected.
