Summary:A method for the quantitative analysis of the spatial relationships of minerals is described. Dispersed distributions are formed by annealing and are destroyed in post-tectonic migmatization; aggregate distributions characterize solid-state differentiation, whereas leucosomes formed in systems of high fluid/rock ratio show random distributions. Such quantitative textural analysis can be used to indicate whether migmatization was post-tectonic or earlier and to discriminate melt-present from melt-absent leucosomes; examples are discussed for a suite of metamorphic and anatectic migmatites from the Scottish Caledonides.
