Svecofennian intra-orogenic gabbroic magmatism: A case study from Turku, southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 2014 Using single-grain zircon U-Pb dating by LA-MC-ICPMS and whole-rock geochemistry, we have studied the Palaeoproterozoic gabbroic rocks from Moisio in southwest Finland. Three ages were obtained.

The Svecokarelian orogenic cycle and related metallogenesis in Finland [PDF]
Bulletin of the Geological Society of Finland, 1975 General features of the Svecokarelian orogenic belt in Finland together with the ore deposits and their environments in the belt are reported. The sedimentary groups, igneous phases and ore deposits are considered functions of the orogeny.

Petrological and geochemical characterization of Abu Murrat syn-orogenic I-type and post-orogenic A-type neoproterozoic granitoids, North Eastern Desert, Egypt [PDF]
Scientific ReportsThe Abu Murrat area, Northern Eastern Desert (NED) of Egypt, exposes two Neoproterozoic granitoid suites recording successive Pan-African evolution. The older syn-orogenic suite comprises quartz diorite, tonalite, and granodiorite, whereas the younger ...

Inboard advance of arc magmatism regulates mountain building in the Andes [PDF]
Nature CommunicationsDebate continues over the mechanisms that govern the tempo and style of arc magmatism and retroarc deformation along ocean-continent plate boundaries. Here we integrate detrital and bedrock geo/thermochronological and geochemical records of Cenozoic arc ...

Passive magmatism on Earth and Earth-like planets
Geosystems and Geoenvironment, 2022 Magmatism has occurred throughout Earth's history. From the early Earth to the modern plate-tectonic Earth, the amount of magmatism has varied, but it has always occurred on multiple scales, in various tectonic environments and at various depths in the ...
