Carbonatite Metasomatism in the Southeastern Australian Lithosphere

New mineralogical and geochemical data from a suite of glass ± from the mantle (Deines & Gold, 1973; Nelson et al., 1988). However, controversy remains as to whether such apatite ± amphibole ± phlogopite ± carbonate-bearing spinel magmas represent (1) direct partial melts of carbonatewehrlite, lherzolite and harzburgite xenoliths from the Newer Volbearing mantle peridotite (i.e. primary carbona...

Small-scale Convection and the Evolution of the Lithosphere

In this thesis we calculate the effect of small-scale convection on the thickness and temperature structure of the lithosphere for three cases where geophysical and geological data may allow us to see these effects. The problems are: (1) the cooling of the oceanic lithosphere; (2) the cooling of a passive rift temperature structure; and (3) the rate of thinning of lithosphere which has been thi...

Thermal evolution of the oceanic lithosphere: an alternative view

The most common model used for representing the evolution with age of the oceanic lithosphere is the ‘plate model’ where the temperature is set at a fixed depth, called the base of the plate. This ‘base of the plate’ has no physical meaning but this model provides a mathematical substitute for a system where small-scale convection occurs through instabilities growing at the base of the cooling ...
