Rapakivi texture in porphyritic dikes within the Karavanke granitic massif (Slovenia) [PDF]

Bulletin of the Geological Society of Finland, 2002
The northern Karavanke Granitic Massif straddles the Slovenian–Austrian border. The investigated area lies in northern Slovenia, and extends from the western Slovenian–Austrian border to the east for about 30 km, with a maximum width of 2 km.

Evidence for magma mixing/mingling process in the plutonic intrusive bodies of Qorveh (Kurdistan Province): with emphasis on textural and geochemical characteristics [PDF]

پترولوژی, 2023
The Qorveh batholith, in the N-Sanandaj-Sirjan Zone, comprises several gabbroic, dioritic and granitic masses intruded the Jurassic metamorphic assemblage (i.e., schist, amphibolite and marble). In spite of a number of studies which have been carried out

In situ mineralisation of UK onshore igneous rocks offers significant CO2 storage potential

Earth Science, Systems and Society
Safe and permanent storage of CO2 will be required to limit global warming to 1.5–2°C above pre-industrial levels. In situ mineralisation of CO2 within igneous rock formations is a rapid and secure method of geological CO2 storage.

Tracing the styles of mafic-felsic magma interaction: A case study from the Ahvenisto igneous complex, Finland [PDF]

Bulletin of the Geological Society of Finland, 2019
The 1.64 Ga Ahvenisto complex, southeastern Finland, is an anorthosite mangerite-charnokite-granite (AMCG) suite in which diverse interaction styles of coeval mafic and felsic magmas are observed.

Low–pressure metamorphism of mafic granulites in the Chinese Altay orogen, NW China: P–T path, U–Pb ages and tectonic implications

Solid Earth Sciences, 2020
Mafic granulites occur as massive lenses within host paragneisses at Wuqiagou area in the southern Chinese Altay orogen. They comprise a suite of fine–grained and coarse–grained mafic granulites, both characterized by an assemblage of orthopyroxene ...

Record of short-lived “orogen” on Eurasian continental margin by South China Sea obduction preserved in Taiwan collision

Frontiers in Earth Science, 2023
The Taiwan mountain belt is the result of an arc-continent collision following the total subduction of the South China Sea and subsequent closure of the Luzon forearc, a process important in the accretionary growth of continents.

Geochemistry and geochronology of the Palaeozoic mafic magmatism in the Codosera, Almadén and Guadalmez synclines, Central Iberian Zone, Spain

BSGF - Earth Sciences Bulletin
The Central Iberian Zone (CIZ) hosts several mafic suites showing variable geochemical affinities and signatures evolving through time. To provide a better understanding of magmatic processes, possible sources and the temporal evolution of the mafic ...

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...
