“…We present a broad range of possible values, because the estimation of effective dissolution rates, porosity and fluid velocity are so uncertain. Several studies have measured dissolution of mantle minerals in basaltic melts at upper mantle pressures and temperatures [41,12,96].…”

“…The first two studies emphasized results for relatively "well-stirred" melts, with narrow chemical boundary layers, while (96] attempted to minimize convection and mixing in liquids surrounding dissolving crystals, maximizing the width of the chemical boundary layer. It is difficult to know which of these apply to the microscopic geometry of melt flow in the mantle, below the continuum or Darcy scale, in which some intergranular pores could be effectively stagnant, while others may carry rapidly moving liquids.…”

“…The fit to the chemical diffusion-profile using our calculated diffusion-coefficients is shown in figure 4-8D, and it is clear that the effective binary diffusion coefficient (EBDC) provide better fits than the traditional diffusion coefficients. Furthermore, the dissolution rates calculated from the diffusion-coefficients (Table 4-6) are smaller for Zhang et al (1989) than the rates determined by volumetric dissolution . This is probably because much of the melt has been pressed out of the interface to the sides of 171 the experiment.…”

“…When minerals precipitate, interface-kÍnetics between the melts and crystals may control the rate at which the crystals grow. However, Zhang et al (1989) used the interface-reaction rates from Kuo and Kirkpatrick (1985) and demonstrated that the interface-melts are saturated with the bounding crystals after ~ 1 second of dissolution, thus there is no interface-control of dissolution in our experiments. The melt-film has a near-constant thickness, as the weight of the overlying mineral squeezes the melt to the sides of the experiment.…”

“…They have also been detected in glass around partially dissolved crystals in various silicate systems by Kuo and Kirkpatrick (1985a, b), Brearley and Scarfe (1986), and Zhang et al (1989) and their convective behaviour has been studied by Donaldson and Hamilton (1987) and Donaldson (1993).…”
