Strontium-isotope stratigraphy: methodology, standard values (SRM987, EN-1, E&A), a new Neogene curve of 87Sr/86Sr against time, its implications for astrochronology ([I]ODP Sites 1146, 1264, U1337, and U1338), and its application to ODP Site 758 (Indian summer monsoon) and IODP Site 1120 (a new age-model) [PDF]

For the standards SRM(NIST) 987, EN-1, and E&A, we present compilations of 87Sr/86Sr from the literature, and 125 new measurements of 87Sr/86Sr, to arrive at recommend values of 0.710 248, 0.709 172, and 0.708 021 respectively, for normalising 87Sr/86Sr ...
