1865 Ma tholeiitic magmatism during an extensional episode of the Svecofennian orogeny: the Kaiplot gabbros in Nagu (Nauvo), southwestern Finland [PDF]
Bulletin of the Geological Society of FinlandThe Svecofennian orogeny in southern Finland has traditionally been divided into two broadly defined compressional stages, the 1.89–1.87 Ga “synorogenic” stage and the ca 1.84–1.81 Ga “lateorogenic” stage.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

MINERAL CHEMISTRY OF OPHIOLITIC GABBROS WITHIN CENTRAL ANATOLIA: HIRFANLI DAM GABBROS
SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2019 The tectonic evolution of the magmatic rocks the Central Anatolia (CA) began at the late Mesozoic with closure of Neotethys in the region. The Central Anatolia has experienced several magmatic events including felsic and mafic intrusions originated from collisional and/or extensional tectonic events. The felsic magmatism of the CA are well reported and

Drilling to Gabbro in Intact Ocean Crust [PDF]
Science, 2006 Sampling an intact sequence of oceanic crust through lavas, dikes, and gabbros is necessary to advance the understanding of the formation and evolution of crust formed at mid-ocean ridges, but it has been an elusive goal of scientific ocean drilling for decades.

Petrography and mineral compositions of gabbros at DSDP Leg 60 Holes
, 1982 The compositions, mineralogies, and textures of gabbros recovered in polymict breccias in Hole 453 indicate that they are the cumulus assemblages of calc-alkalic crystal fractional on that occurred beneath the West Mariana Ridge.
