In order to better characterise mantle CO2/Nb-variability, we obtained and compiled major and trace elements, content and isotope composition of both CO2 and water on two series of mid-ocean ridge basalt (MORB) samples dredged at ∼ 14° N (n = 6) a

This article presents the first results of chlorine residual salt analysis (Cl-RSA), a new technique that allows investigation of the isotopic composition of chlorine in oil-field waters from core analysis. As water evaporates, the residual salts pre

We analyzed CO2–δ13C–H2O–δD in vesicles of a suite of 23 vesicular submarine volcanic glasses (4 alkalic basalts and 19 trachytes) from Teahitia, Volcano 4 and Rocard seamounts and Mehetia Island in the active area of the Society hotspot (Fre

The carbon and water contents and the corresponding isotopic compositions have been measured on a set of glassy samples collected by dives on the Mid-Atlantic Ridge (MAR) near 34°50′N where volcanoclastic deposits are present. The volatile phases

Secondary ion mass spectrometry (SIMS) offers unparalleled capability for the in situ determination of chlorine stable isotope ratios ( δ 37 Cl) in small objects, such as igneous melt inclusions. However, SIMS analyses must be carefully calibrated f

A collection of 24 seawaters from various worldwide locations and differing depth was culled to measure their chlorine isotopic composition (δ37Cl). These samples cover all the oceans and large seas: Atlantic, Pacific, Indian and Antarctic oceans, M

Vesicle characteristics (vesicularity, largest vesicle size, number of vesicles/cm2), CO2–δ13C and CO2–4He–40Ar–40Ar/36Ar in vesicles and CO2–δ13C in the glass have been measured in 19 tholeiitic basalt glasses from the Easter Microplate

In order to better constrain the origin of volatile variability of mid ocean ridge basalt (MORB), we have performed crushing analyses on 33 fresh basaltic glasses. Most samples originate from the Southwest Indian Ridge (i.e. 78–49°E, EDUL cruise,

Submersible observations and sampling were carried out in the rift valley of the Mid-Atlantic Ridge (MAR) near 34°40′N–35°N. The 4-km-wide rift valley consists of a Neo Volcanic Zone (NVZ) ( K/Ti=0.25−0.45, Na 2 O+K 2 O>2.8−3.2 %) and alkal
