Constraints on Ordovician and Carboniferous magmatism in the Carpathian–Pannonian region: New petrological and geochronological insights from the Tisza–Dacia and ALCAPA Mega-units (Hungary and Romania)

Máté Szemerédi, Andrea Varga, István Dunkl, Réka Lukács et autres

Carboniferous–Permian magmatic rocks are common in the Carpathian–Pannonian region, whereas Cambrian–Devonian (meta)igneous associations are less frequent and not yet confirmed by radiometric data in the basement of the Pannonian Basin. The major goal of this study was to constrain Ordovician zircon U–Pb …

Amphibole trace element signatures of magmatic environments within the magmatic plumbing system of the 160–30 ka Ciomadul volcanic complex, Eastern Carpathians

Barbara Cserép, Saskia Erdmann, Réka Lukács, Olivier Bachmann et autres

Amphibole is a common mineral in arc magmas, occurring in a wide temperature and pressure range. Its composition is sensitive to the crystallization condition that helps to quantify the magma storage depth, temperature, and redox conditions as well as to characterize the …

Constraints on the pre-eruptive magma storage conditions and magma evolution of the 56–30 ka explosive volcanism of Ciomadul (East Carpathians, Romania)

Barbara Cserép, Máté Szemerédi, Szabolcs Harangi, Saskia Erdmann et autres

Abstract A detailed mineral-scale study was conducted on pumices of the latest, dominantly explosive eruption epoch (56–30 ka) of Ciomadul, the youngest, long-dormant volcano in eastern-central Europe for characterizing the magma storage system and for understanding better the changes in eruption style …

Large-volume Permian felsic volcanism in the Tisza Mega-unit (East-Central Europe): Evidence from mineralogy, petrology, geochemistry, and geochronology

Máté Szemerédi, Andrea Varga, Réka Lukács, István Dunkl et autres

Permian felsic volcanic rocks are widespread in the Tisza Mega-unit (Carpathian–Pannonian region), covering a relatively large area from southern Transdanubia (Hungary) to the Apuseni Mountains (Romania). The present occurrence and structural position of these Permian volcanic rocks are the result of a …

Máté Szemerédi, Zoltán Kovács, István Dunkl, Réka Lukács et autres

Two-mica leucogranites and/or granodiorites, often affected by various degrees of post-emplacement deformation and/or metamorphism (i.e., sheared granites, metagranites or orthogneisses), occur in several parts of the Tisza Mega-unit (Carpathian–Pannonian region), including the Apuseni Mts. (Romania), the Papuk Mt. (Croatia), and basement highs …

Petrographic traces of open-system magmatic processes in the felsic suite of the Ditrău Alkaline Massif (Eastern Carpathians, Romania)

Luca Kiri, Máté Szemerédi, Elemér Pál‐Molnár

The Ditrău Alkaline Massif (DAM; Eastern Carpathians, Romania) is a unique pluton with a presently tilted vertical cross-section of a pre-existing alkaline magma storage system, which consists of various rock types from ultramafic cumulates to granitoid rocks, crosscut by lamprophyre, syenite, ijolite …

Petrographic evidences of open-system magmatic processes in the felsic rocks of the northern part of the Ditrău Alkaline Massif (Eastern Carpathians, Romania)

Luca Kiri, Máté Szemerédi, Elemér Pál‐Molnár

Abstract Over the almost 190 years-long research of the Ditrău Alkaline Massif (Eastern Carpathians, Romania), felsic rocks have been regarded as homogeneous, uniform units of the igneous complex. Nevertheless, our detailed textural study revealed that the felsic suite (diorite–alkaline feldspar syenite and …
