The structure and petrology of the Cnoc nan Cuilean Intrusion, Loch Loyal Syenite Complex, NW Scotland [PDF]
, 2013 In NW Scotland, several alkaline intrusive complexes of Silurian age intrude the Caledonian orogenic front. The most northerly is the Loch Loyal Syenite Complex, which is divided into three separate intrusions (Ben Loyal, Beinn Stumanadh and Cnoc nan ...

The Alkaline Intrusion of Cananéia on the South Coast of São Paulo State: Geology and Geochronology [PDF]
Geologia USP. Série Científica, 2008 New radiometric ages (Ar-Ar and Rb-Sr) are available for the alkaline rocks from the Cananéia massif in the so-called Ribeira Valley, which is represented by two small bodies (Morro de São João, 1.8 km2, and Morrete, 0.4 km2).

Petrogenetic processes in the ultramafic, alkaline and carbonatitic magmatism in the Kola Alkaline Province: a review [PDF]
, 2005 Igneous rocks of the Devonian Kola Alkaline Carbonatite Province (KACP) in NW Russia and eastern Finland can be classified into four groups: (a) primitive mantle-derived silica-undersaturated silicate magmas; (b) evolved alkaline and nepheline syenites; (

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]
, 2006 Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

The Cananeia Alkaline Body in the South Coast of São Paulo State: Mineral Chemistry [PDF]
Geologia USP. Série Científica, 2009 The Cananeia alkaline occurrence of Late Cretaceous age (Ar-Ar, 83.6 Ma) lies in the Ribeira Valley and it is representedby two small bodies: Morro de São João (1.8 km2) in Cananeia Island, and Morrete (0.4 km2), in the neighboringComprida Island.

Volcanica, 2023 The ~30 Ma to Recent Wrangell Arc (WA), Alaska is an ideal location to study subduction and slab-edge magmatism. However, the WA covers a huge area (~15,000 km2) and ~29% of the WA is covered by glaciers with rugged topography, making bedrock sampling ...
