[ES] Se consideran los aspectos químicos y fisicoquímicos de la mineralogénesis plutónica, en su entorno geológico, discutiéndose la posible aplicación de los rasgos genéticos de los magmas a las mineralizaciones presuntamente derivadas y descartándose algunos mecanismos propuestos de formación de fundidos graníticos y de los depósitos con ellos implicados. La clasificación en granitos 1 y 5, con mineralizaciones estanníferas vinculadas a estos últimos, es inaplicable en la region. Por otra parte, se expone la teoría de la migración de los coloides (que darán lugar a los constituyentes de las menas) desde su formación a partir de los complejos químicos solubles hasta su deposición.
[EN] Several proposed mechanisms of granite genesis and relations between some types of those with Sn-deposits are considered. The classifícation in two contrasting granitoid types, 1 and 5, and the connection of these with the S-type have been accepted as ineffective in Central Iberia. By the other hand, the colloidal migration theory, for mineral particles, is exposed. Their mechanism begins with the solid genesis from chemical dissociations of dissolved complexes.
