Strontium isotopes in tap water from the coterminous USA

, 2012
Strontium isotope analysis has proven useful in geo-location investigations of organic and inorganic materials and may complement the region-of-origin information provided by hydrogen and oxygen stable isotope analysis.

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]

, 2007
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.

Bose-Einstein condensation of 86Sr

, 2010
We report on the attainment of Bose-Einstein condensation of 86Sr. This isotope has a scattering length of about +800 a0 and thus suffers from fast three-body losses.

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Isotopic investigation of human provenience at the eleventh century cemetery of Ndr. Grødbygård, Bornholm, Denmark

Danish Journal of Archaeology, 2012
Bornholm is a Danish island almost in the center of the southern Baltic Sea. The strategic location of the island, its rich archeology, and its complex geology make it an intriguing location for the isotopic study of past human mobility.

Strontium isotope stratigraphy: LOWESS version 3: best fit to the marine Sr-isotope curve for 0-509 Ma and accompanying look-up table for deriving numerical age [PDF]

, 2001
An improved and updated version of the statistical LOWESS fit to the marine 87Sr/86Sr record and a revised look-up table (V3:10/99; available from j.mcarthur@ucl.ac.uk) based upon it enables straightforward conversion of 87Sr/86Sr to numerical age, and ...

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, EarlyView.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Formation of ultracold SrYb molecules in an optical lattice by photoassociation spectroscopy: theoretical prospects

, 2011
State-of-the-art {\em ab initio} techniques have been applied to compute the potential energy curves for the SrYb molecule in the Born-Oppenheimer approximation for the ground state and first fifteen excited singlet and triplet states within the coupled ...
