- W282128331 abstract "Although it is mostly employed to estimate the amount of crystallization needed to form the observed members of a magmatic suite from a given parental magma, the Rayleigh distillation equation can also be used to quantitatively model igneous variation trends. On a simple x-y variation diagram there are four geometrically possible combinations of slope (+ or -) and curvature (up and down), but differentiation of the Rayleigh equation using the method of parametric equations shows that one of these four patterns is mathematically forbidden. However, this forbidden curvature is, in fact, observed in a number of simple comagmatic suites. This inadequacy in the simple Rayleigh equation was overcome by developing a physical model that takes into account the role of preexisting solid crystals in the magmatic fractionation process. These phenocrysts act as relatively inert particles that are concentrated into the cumulates that accrete at the crystallization interface along the chamber's walls. Moreover, the abundance of phenocrysts in the residual magma is progressively diluted by the remixing of fractionated melts that escape from this zone of dynamic crystallization. Using existing distribution coefficients, this model is able to elegantly explain the occurrence of forbidden curvature. Additionally, the model offers powerful insights intomore » the origin of granitic textures and provides the key to interpreting the bulk line of descent (as distinct from the liquid line of descent).« less" @default.
