McKenzie model

The heat flow model used in this study, as described above, is based on a McKenzie model of exponential decreasing heat flow after the latest tectonic rifting event in late Jurassic-Early Cretaceous.

Because of the difficulty in explaining the observed U-series excesses by time-independent models, interpretations of how disequilibria are created have evolved into models based on residence times. In these models, a melt phase coexists with the solid mantle but moves relative to it due to a driving force, most typically buoyancy. The physical situation under ridges can be referred to as two-phase flow because both the solid and the liquid flow. McKenzie (1984) and Scott and Stevenson (1984, 1986) derived the equations describing flow in a viscously deforming porous media. McKenzie...

Several models relating the isotopic effects of U-series disequilibria to the timescales of the melting process have now been proposed (e.g., McKenzie 1985 Williams and Gill 1989 Spiegelman and Elliott 1993 Qin 1992 Iwamori 1994 Richardson and McKenzie 1994). While these models differ mainly in their treatment of the melt extraction process (i.e., reactive porous flow vs near fractional melting), because they incorporate the effect...

These equations converge towards those of the fractional melting model for tp Dh and, contrary to McKenzie (1985) equation (29), CUq tends to C0 when porosity partition coefficient are of the same order of magnitude, large variability is achieved in both the solid and the residue, a point which will be returned below. Considerable attention has been recently focussed on this model which may explain the fractionation of some strongly incompatible nuclides in the U decay series (McKenzie, 1985 Williams and Gill, 1989 Beattie, 1993).

We use the physical concept of the dynamic melting model proposed by McKenzie (1985) for the situation where the rate of melting and volume porosity are constant and finite while the system of matrix and interstitial fluid is moving. This requires that the melt in excess of porosity be extracted from the matrix at the same rate at which it is formed (the details of the model are shown in Fig. 3 of McKenzie, 1985).

Because woodchuck hepatitis virus is similar to human hepatitis B, that rodent is a good animal model for the infection. McKenzie et al. followed the development in woodchucks of hepatocellular carcinoma arising from the infection over 6 months using P 2D MRSI. They attributed the increased ratio of PME/(3-NTP to increased cellular proliferation of the liver tumour.
