“…Both RE and Sr Resins are so selective that reusing resins has not been recommended (M. J. Fern, personal communication, 1994;Pin and Bassin, 1992;Pin et al, 1994;Pin and Santos Zalduegui, 1997). After passing a chondritic sample containing 110 ng of strontium through the column of freshly packed Sr Resin, we found an extremely high "carry-over" of strontium (1.4 ng) from one sample to the next.…”

A new separation scheme for rare earth elements (REE) and strontium, and its application to REE determination of chondrites and terrestrial rocks along with isotopic analysis of strontium in chondritic meteorites are presented. The miniaturized extraction chromatography scheme using RE and Sr Resins provide simple and effective methods for the isolation of REE and strontium from chondritic meteorites. Chemical yields of up to 90% of the desired elements and low procedural blanks enable us to use the resins for small-size chondritic meteorite samples, weighing one to five milligrams. The techniques presented here are fully applicable to Rb-Sr isotopic systematics and to REE geochemistry and cosmochemistry. A separation procedure of lead from total rock basalt samples using Sr Resin is also briefly described.

“…Furthermore, Tl normalisation seems to reduce a potential matrix effect. In addition, samplestandard bracketing was applied to control potential random instability of the instrument as a whole, Chemical purification of Sr (~3 µg) was performed, on the HBr leachate, using an ion-exchange column (Sr-spec) before mass analysis according to a method adapted from Pin and Bassin (1992), with a total blank of less than 1 ng for the entire chemical procedure. After chemical separation, around 150 ng of Sr was loaded onto a tungsten filament with tantalum activator and analysed on a MAT 262 Thermo-Ionisation Mass Spectrometer (TIMS; Finnigan).The 87 Sr/ 86 Sr ratios were normalised to a 87 Sr/ 86 Sr ratio of 0.1194.…”

Even after its being phased out in gasoline in the late 90's, lead (Pb) is still present at relatively high levels in the atmosphere of Beijing, China (0.10-0.18 μg.m -3 ). Its origin is subject to debate as several distinct sources may contribute to the observed pollution levels. This study proposes to constrain the origin(s) of Pb and strontium (Sr) in aerosols, by coupling both Pb and Sr isotope systematics. The characterisation of the main pollution sources (road traffic, smelters, metal refining plants, coal combustion, cement factories, and soil erosion) shows that they can unambiguously be discriminated by the multi-isotope approach ( 206 Pb/ 204 Pb and 87 Sr/ 86 Sr). The study of total suspended particulates (TSP) and fine particles (PM 2.5 ) from Beijing and its vicinity indicates that both size fractions are controlled by the same sources. Lead isotopes indicate that metal refining plants are the major source of atmospheric lead, followed by thermal power stations and other coal combustion processes. The role of this latter source is confirmed by the study of strontium isotopes. Occasionally, emissions from cement plants and/or input from soil alteration are isotopically detectable.

In the Central Iberian Zone synorogenic (syn-and late-D 3 , the last deformation phase) composite batholiths of biotite-rich granitods with peraluminous character are well represented. We report here U-Pb zircon and monazite ages, geochemical, Sr-Nd-O isotopic data and Anisotropy of Magnetic Susceptibility (AMS) studies for the late-D 3 Vieira do Minho pluton, in northern Portugal. AMS reveals the paramagnetic behaviour of these granites and the magnetic fabric enhances the major role of NW-SE regional anisotropies on controlling the ascent and emplacement of the magmas. Magnetic anisotropy and medium temperature microstructures also point out the evolution of regional tectonics during crystallization of the magma. U-Pb zircon and monazite analyses yield consistent ages of 310 ± 2 Ma and 312 ± 2 Ma, interpreted as emplacement age. The Vieira do Minho pluton consists of two peraluminous monzogranites, the VMG and the MRG. Both have similar ε Nd values (VMG= −5.2 to −5.7; MRG =−4.98 to −5.96) but the VMG is slightly enriched in 87 Sr/ 86 i = 0.7087-0.7098 as well as in δ 18 O in the range of 10.6‰ to 11.0‰ than the MRG with 87 Sr/ 86 i =0.7064-0.7075 and δ 18 O=9.9‰-10.5‰. These granites are associated with coeval scarce grabroic intrusions and/or mafic microgranular enclaves which are not considered as mafic precursors of the associated granitic magmatism. Instead, a lower metaigneous crustal source, at different levels, is proposed based on the available data set.
