RT Journal Article T1 Morfología de los circones como indicadores petrogenéticos de la asociación tonalita-leucogranito: El caso del plutón de Zarza la Mayor (Cáceres-España) T1 Zircon morphology as a petrogenetic indicators in the tonalite-leucogranite association; Zarza la Mayor plutoncase (Cáceres, Spain) A1 Rubio Ordóñez, Álvaro A1 Corretgé Castañón, Luis Guillermo A1 Cuesta, Andrés AB Zarza la Mayor pluton is a good example of the tonalite-leucogranite association. A new survey has beencarried out and some additional study of zircon morphologies has been performed. Detailed surveyshows the true intrusive character of the leucogranite pinpointing to a ring-dyke emplacement mechanism.Zircon morphologies show different characteristics for the tonalite (anatectic, with zircon typologies S1-Q1-L1) and leucogranite (calc-alkaline, with zircon typologies S6-Q2). This apparent paradox is explainedtaking care of the strong assimilation of CXG metasediments (Neoproterozoic - Lower Cambrian) by adioritic-tonalitic magma through piecemeal-stopping processes YR 2006 FD 2006 LK http://hdl.handle.net/10272/8503 UL http://hdl.handle.net/10272/8503 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
