Response of the Rb–Sr system in biotite during contact metamorphism in the aureole of the Makhavinekh Lake Pluton, Labrador [PDF]
GeochronologyHigh-temperature contact metamorphism in the aureole of the 1322 Ma Makhavinekh Lake Pluton, Labrador, led to progressive consumption of 1850 Ma garnet formed during upper-amphibolite facies regional metamorphism that produced migmatitic paragneiss ...

Factors conditioning the content of chemical elements in soil and mosses in Armenia
Journal of Trace Elements and Minerals, 2022 In this research, chemical element contents were determined using the Epithermal neutron activation analysis (Cr, V, Ti, Sr, Rb, As, Zn, Co, Fe, Mn and Ba) and atomic-absorption spectrometry (Cu and Pb) for mosses and X-ray fluorescence spectroscopy (Cr,

Rb-Sr isotopic systematics of lherzolitic shergottite Yamato-793605 [PDF]
, 2001 P(論文)We have undertaken a Rb-Sr isotopic study of the lherzolitic shergottite, Yamato (Y)-793605. The acid-leaching experiment designed to remove secondary Pb contamination during previous work with U-Th-Pb systematics did not significantly affect the Rb-

LA‐ICP‐MS/MS Single‐Spot Rb‐Sr Dating
, 2022 Due to developments in reaction cell technologies, it is now possible to collect large Rb-87/Sr-86 and Sr-87/Sr-86 data sets using LA-ICP-MS/MS. Until now, LA-ICP-MS/MS Rb-Sr ages were constrained using conventional isochrons on a contiguous set of Rb-Sr

Rb-Sr and Sm-Nd dating of olivine-phyric shergottite Yamato 980459: Petrogenesis of depleted shergottites [PDF]
, 2005 P(論文)Martian meteorite Yamato (Y) 980459 has undergone terrestrial weathering in Antarctica. The weathering has affected the Sm-Nd isotopic system. Acid-washed pyroxenes, whole rock and quenched glass samples define a Sm-Nd isochron age of 472±47 (±2σ ...

Transport of Rb and Sr to the ear in mature, excised shoots of wheat: Effects of temperature and stem length on Rb removal from the xylem [PDF]
, 1991 Wheat (Triticum aestivum L. cv. `Arina') shoots grown in the field were excised post-anthesis and incubated in the laboratory for 72 h standing in 2 mM RbCl + 2 mM SrCl2. Strontium is a phloem-immobile, xylem-mobile element and indicates the distribution
