Geochemistry of alkaline igneous rocks (Ditrău Alkaline Massif)

Amphiboles of the Ditrău Alkaline Massif’s rocks

The study contains geochemical properties (pressure, temperature) determination of amphiboles in the alkaline system and magma storage modelling with amphibole thermobarometry.

Investigation of pyroxenes from the Ditrău Alkaline Massif


Mafic and ultramafic cumulate rocks from the Ditrău Alkaline Massif

The Ditrău Alkaline Massif in the Eastern Carpathians (Romania) is a Mesozoic alkaline igneous complex, which was formed during an extended phase of the Alpine orogeny related to a rifted continental margin adjacent to Tethys. The mafic–ultramafic cumulates crop out in the north- and central west and western part of the massif. They are enclosed in gabbroic–dioritic rocks as lenticular or block shaped bodies and in the western part the nephelinesyenite are closed in the ultramafic cumulates. These possess important information concerning the magma’s genetics and evolution stages. In this research we investigate the petrographic, geochemical and mineral chemistry of the mafic and ultramafic cumulates, evaluating the petrogenesis of these rocks.

Mingling and mixing process in the Ditrău Alkaline Massif

The aim of the study is the research of the mingling and mixing process in the alkaline system (between two or more magmas); macroscopic and microscopic analysis of these structures and textures and survey of the geochemical evidences of the mingling and mixing process.

Alkaline magmatism’s dyke phases of the Ditrău Alkaline Massif

Relationships of the alkaline systems: basaltic (basanitic) and foidsyenite, alkaline syenite together with alkaline granite
