Abstract
Un horizonte carbonatado hemipelágico entre pizarras del Complejo
Maláguide del Corredor de Vélez Rubio-Lorca ha proporcionado conodontos
del Bashkiriense basal-Moscoviense medio. Esta edad es equivalente a (o ligeramente
más moderna que) la de los clastos de calizas con fósiles marinos
someros identificados en el Conglomerado de Marbella, que eran hasta
la fecha los elementos más modernos reconocidos en el Paleozoico maláguide.
Este hallazgo revela una paleogeografía carbonífera en el Dominio
Maláguide algo más compleja de lo que hasta ahora se sospechaba, y pone
de manifiesto la persistencia, en dicho dominio, de una zonación de ambientes
de plataforma somera a cuenca hemipelágica hasta el Carbonífero
tardío
A hemipelagic carbonate horizon interbedded with slates in the Malaguide Complex outcropping in the Vélez Rubio-Lorca Corridor provided a lowermost Bashkirian-middle Moscovian conodont association. This age is equivalent, or slightly younger, to the limestone boulders bearing shallow marine fossils found in the Marbella Conglomerate, which were the youngest beds found, up to now, in the Malaguide Paleozoic. This finding reveals that the Carboniferous palaeogeography in the Malaguide Domain was more complex than previously suspected, and that a lateral transition from shallow marine carbonate platforms to hemipelagic basinal environments persisted in this domain up to, at least, the late Carboniferous
