The orbicular granodiorite of the Cordon de Lila is emplaced within the Ordovician pluton El Leon, in the southeastern part of Cordon de Lila. This forms a small pipe emplaced in an aplitic band, near the contact with a roof-pendant of amphibole bearing gabbro. The presence of allanite, considered a tracer mineral in magmatic crystallization processes, in the three facies that constitute the pipe (core, margin and matrix) suggests that the orbicules of this granodiorite are the result of magmatic crystallization that affected the magma that originated the orbicular granodiorite.
