Boron isotope fractionation in magma via crustal carbonate dissolution

Carbon dioxide released by arc volcanoes is widely considered to originate from the mantle and from subducted sediments. Fluids released from upper arc carbonates, however, have recently been proposed to help modulate arc CO2 fluxes. Here we use boron as a tracer, which substitutes for carbon in limestone, to further investigate crustal carbonate degassing in volcanic arcs. We performed laborat...

Boron isotope geochemistry during diagenesis. Part I. Experimental determination of fractionation during illitization of smectite

Experiments were performed to measure the isotopic fractionation of boron between illite/smectite (I/S) clay minerals and water as a function of temperature (300° and 350°C) and degree of illitization. Corresponding changes in the oxygen isotopes were monitored as an indication of the approach to equilibrium. The kinetics of the B-isotope exchange follows the mineralogical restructuring of smec...

Chromatographic observation of boron isotopic fractionation between kaolin clay and boron bearing solution: A high pressure experiment

In order to determine the boron isotopic fractionation factor between boron adsorbed onto kaolin clay and boron in solution (S), as a first attempt, a break-through column chromatography at a high pressure (12.0 MPa) was performed. A boric acid standard solution (9.25 mmol/l, NIST SRM 951) was fed into a stainless steel column packed with boron-free kaolin clay with the flow rate of 0.8 ml/h. T...

Boron isotope geochemistry during diagenesis. Part II. Applications to organic-rich sediments

The measured clay-water isotope fractionation for boron was applied to natural organic-rich sediments undergoing illitization. Two field areas were chosen that show illitization occurring over a range of temperatures (80–500°C). Samples representing diagenetic temperatures of illitization (80–200°C) are from the Gulf of Mexico sedimentary basin at 4 to 6-km depth in the Eocene Wilcox Fm and Jur...
