Application of retardation filters has revolutionized the use of multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) for the measurement of U-series disequilibria. Here, we present an evaluation of the application of retardation e

Trace Element and Isotopic Evidence for Recycled Lithosphere from Basalts from 48 to 53°E, Southwest Indian Ridge

Autor: Conghui Wang, Vincent J. M. Salters, Jixin Wang, Jared J Standish, Huaiyang Zhou, Henry J. B. Dick

Publikováno v: Journal of Petrology. 61

Mantle source heterogeneity and magmatic processes have been widely studied beneath most parts of the Southwest Indian Ridge (SWIR). But less is known from the newly recovered mid-ocean ridge basalts from the Dragon Bone Amagmatic Segment (53°E, SWI

Constraints on the mantle mineralogy of an ultra-slow ridge: Hafnium isotopes in abyssal peridotites and basalts from the 9–25°E Southwest Indian Ridge

Autor: S. Mallick, Michael Bizimis, Jared J. Standish

Publikováno v: Earth and Planetary Science Letters. 410:42-53

We report on the Hf isotopic compositions of clinopyroxene mineral separates from eleven abyssal peridotites and Nd and Hf-isotopic compositions of twenty-seven co-located basalts from 9–25°E South West Indian Ridge (SWIR). In Nd–Hf isotope spac

Heterogeneous upper mantle Ne, Ar and Xe isotopic compositions and a possible Dupal noble gas signature recorded in basalts from the Southwest Indian Ridge

Autor: Jared J. Standish, Rita Parai, Sujoy Mukhopadhyay

Publikováno v: Earth and Planetary Science Letters. :227-239

Variations in heavy noble gas (Ne, Ar, Xe) isotopic compositions provide unique insights into the nature of heterogeneities in the mantle. However, few precise constraints on mantle source heavy noble gas isotopic compositions are available due to ub

Young off-axis volcanism along the ultraslow-spreading Southwest Indian Ridge

Autor: Jared J. Standish, Kenneth W.W. Sims

Publikováno v: Nature Geoscience. 3:286-292

The growth of oceanic plates at mid-ocean ridges, crustal accretion, occurs by a combination of magmatic and tectonic processes. Magmatic processes along ridges spreading at fast, intermediate and slow rates, continually add volcanic material to a ce

Multistage magma mingling and the origin of flow banding in the Aliso lava dome, Tumacacori Mountains, southern Arizona

Autor: Sheila J. Seaman, Erik E. Scherer, Jared J. Standish

Publikováno v: Journal of Geophysical Research: Solid Earth. 100:8381-8398

Flow banded rocks of the middle Tertiary Aliso lava dome, in the Tumacacori Mountains of southern Arizona, contain light-colored dacitic flow bands, dark-colored rhyolitic flow bands, and dark-colored ellipsoidal enclaves of rhyolite. Groundmass glas

MORB generation beneath the ultraslow spreading Southwest Indian Ridge (9-25°E): Major element chemistry and the importance of process versus source

Autor: Peter J. Michael, Jared J. Standish, Timothy O'Hearn, William G. Melson, Henry J. B. Dick

Publikováno v: Geochemistry, Geophysics, Geosystems. 9

[1] We report highly variable mid-ocean ridge basalt (MORB) major element and water concentrations from a single 1050-km first-order spreading segment on the ultraslow spreading Southwest Indian Ridge, consisting of two supersegments with strikingly

An inter-laboratory assessment of the thorium isotopic composition of synthetic and rock reference materials

Publikováno v: GEOSTANDARDS AND GEOANALYTICAL RESEARCH. 32(1)

We present a concerted international effort to cross-calibrate five synthetic Th isotope reference materials (UCSC Th "A", OU Th "U", WUN, IRMM-35 and IRMM-36), and six rock reference materials (UCSC TML, Icelandic ATHO, USGS BCR-2, USGS W-2, USGS BH
