Boninite petrogenesis: Chemical and Nd-Sr isotopic constraints
Earth and Planetary Science Letters, 1983Major and trace element abundances and Nd and Sr isotopic compositions have been determined for boninites from the Bonin Islands, Cape Vogel (Papua New Guinea) and New Caledonia and for similar lavas from Cyprus and New Zealand. SiO 2 , CaO, incompatible element abundances and e Nd values are shown to vary systematically with the degree of light rare ...

Sr and Nd isotope systematics in fish teeth
Earth and Planetary Science Letters, 1985High concentrations of Sr and Nd in fish teeth apatite (up to 2000 and 3800 ppm. respectively) make them relatively impervious to diagenetic overprints and allow high-precision analysis of87Sr/86 Sr and143Nd/144Nd of very small amounts of material.87Sr/86Sr ratios of 14 Cenozoic samples (< 55 Ma) from the Atlantic, Indian, and Pacific Oceans and the ...

Sr isotope evolution during chemical weathering of granites
Science in China Series D: Earth Sciences, 2001The Sr isotopic systematics in the weathering profiles of biotite granite and granite porphyry in southern Jiangxi Province were investigated. The results showed that during the chemical weathering of granites, remarked fractionation occurred between Rb and Sr.

Sr isotopic constraints on the process of glauconitization
Geology, 1992Sr isotopic data of Holocene glauconitic pellets suggest a twofold glauconitization process that is strongly linked to the detrital clay minerals from surrounding mud which act as precursors until the K2O content of the glauconitic material reaches 4%. Above that, a detectable sea-water influence becomes progressively predominant.
