Abstract

In the Central System of Spain outcrop se vera I dyke swarms of late-hercynian age. They are
mainly composed by granitic porphyry and microdioritic dykes. The last one, when globaly considered,
show scattering in the contents of most of the major and trace elements. When we study the
individual microdioritic swarms, it can be observed that they exhibit more defined compositional and evolutionary trends. These trends are different from one microdioritic swarm to another. The
variations can be justified by different crystal fractionation models and reflect heterogeneities in the
source or differences on the melting process.
