Localisation of Ancient Migration Pathways inside a Fractured Metamorphic Hydrocarbon Reservoir in South-East Hungary

Applied Sciences, 2020
Numerous fractured hydrocarbon reservoirs exist in the metamorphic basement of the Pannonian Basin in Hungary. Many decades of experience in production have proven that these reservoirs are highly compartmentalised, resulting in a complex mosaic of ...

Petrology and P-T condition of white mica-chlorite schists from Vlasina series - Surdulica, SE Serbia [PDF]

Geološki Anali Balkanskoga Poluostrva, 2002
This paper reports structural, textural, petrological and metamorphic data from Vlasina Series of greenschists rocks (as part of the Upper Complex of the Serbo-Macedonian Massif) within which group of white mica-chlorite schist are extensively developed.

Varying processes, similar results: How composition influences fragmentation and subsequent feeding of large pyroclastic density currents

Frontiers in Earth Science, 2022
Unlike their silicic counterparts, mafic eruptions are known for being on the low-end of the explosivity spectrum with eruption styles commonly ranging from effusive to Hawaiian fire fountaining.

Constraining Magma Reservoir Conditions by Integrating Thermodynamic Petrological Models and Bulk Resistivity From Magnetotellurics

Geochemistry, Geophysics, Geosystems, 2022
Magnetotelluric (MT) data image the bulk resistivity of the subsurface which can be used to infer magma reservoir conditions beneath volcanoes. The bulk resistivity of magma depends primarily on the melt volume fraction, temperature, and water content ...

Bringing the Field into the Classroom by Using Dynamic Digital Maps to Engage Undergraduate Students in Petrology Research [PDF]

, 2004
This article describes the use of Dynamic Digital Maps (DDMs) in undergraduate petrology courses. A DDM is a stand-alone computer program that presents interactive geologic maps, digital images, movies, animations, text and data.

Theoretical petrology [PDF]

, 1979
The central issues in petrology have remained remarkably unchanged in the last 50 years. In igneous petrology, the focus is on understanding the nature and cause of diversity in igneous rocks: on identifying primary magma types and constraints on the ...

Structural controls on petroleum migration and entrapment within the faulted basement blocks of Szeghalom Dome (Pannonian Basin, SE Hungary)

Geologia Croatica, 2015
 The basement of the Pannonian Basin contains several fractured metamorphic hydrocarbon reservoirs that typically form structural highs between the Neogene sedimentary sub-basins.
