Pumice samples from Fukutoku-oka-no-ba in the Izu±Bonin ± Mariana (IBM) arc were analysed for 40 trace elements and Sr, Nd, and Pb isotopic compositions. These samples are shoshonites (59.4±61.8 wt% SiO2), characterized by high contents of K2O (3.74±4.64 wt%), Ba (1274±1540 p.p.m.), Rb (91±105 p.p.m.), and light rare earth elements. The characteristics of alkali-element enrichment are similar t...

Abstract. The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface Earth are powerful tools for tracing dust sources sinks Earth's surface. To differentiate between spatial variabilities in eolian key cryospheric regions at three poles (the Arctic; Antarctica; “third pole”, covering high mountainous area Asia), a dataset Sr–Nd isotopic from extremely cold or arid ...

Trace metal atmospheric contamination was assessed in one of the oldest European industrial sites of steel production situated in the southern part of the Grand-Duchy of Luxembourg. Using elemental ratios as well as Pb, Sr, and Nd isotopic compositions as tracers, we found preliminary results concerning the trace metal enrichment and the chemical/isotopic signatures of the most important emissi...

Abstract The identification of an eroded fore-arc crust component in arc magmas is challenging due to the combined effects mantle metasomatism and crustal assimilation–fractional crystallization. In this study, molybdenum (Mo) isotope compositions are used conjunction with Sr-Nd-Hf isotopic elemental data identify components adakites from Cuyapo Balungao volcanoes northern Bataan segment Luzon ...

The exceptional development of lateritic profiles make the Amazon one best places to conduct a refined study on effects long-term tropical climate Earth's surface rocks. Concentrations Nd and Sr isotopes, as well rare earth elements (REE), Sr, other trace were determined in six order shed new light into element behavior processes controlling geochemistry transfer these among different compartme...

Abstract New geochemical data, including Sr–Nd–Pb isotopes for whole-rock and groundmass samples, are reported edifice-forming eruptives at Tongariro volcano, Zealand, which span its ~ 350 ka to late Holocene history. medium-K basaltic-andesites dacites (53.0–66.2 wt% SiO 2 ) that evolved via assimilation-fractional crystallisation (AFC) processes partly or mostly in the uppermost 15 km of crus...

Apatite Sr-Nd and zircon Hf-O isotopes are broadly used to trace magma sources constrain evolution processes, further improving our understanding of the origin granitoids. We present U-Pb ages, whole-rock major elements, Sr-Nd-Hf, Hf-O, apatite isotopic data for coarse-grained quartz monzonite, biotite monzogranite, granite porphyry in Yushulinzi pluton Liaodong Peninsula, eastern North China C...

The ratios of stable isotopes of certain elements in rocks and minerals have strong regional characteristics that are reflected in atmospheric components, in water, and in the living organisms that form Earth's surface environment as well as in agricultural and fishery products. Geologically derived stable isotope ratios can be used as a tracer for the source of many kinds of substances, with c...
