The Sedemte Prestola pluton is an intermediate to acid plutonic body of Variscan age (308.7 ± 9.1 Ma). Despite its small size, several petrographic varieties are present: syenites, quartzsyentes and granites. It composed potassium feldspar, quartz, sodic-calcic amphibole; biotite, when present, often rimmed by amphibole or strongly altered; zircon, titanite, apatite ilmenite the accessory phase...

Fluorite mineralization was studied in the Variscan granitoid Karkonosze pluton northern part of the Bohemian massif (Lower Silesia, Poland). Fluid inclusions fluorite and quartz were investigated by following methods: heating freezing on an immersion microscope stage, spectrophotometric electron probe analysis, calcination water leachate. The parent fluids Na-Ca-Cl type with a low CO₂ content....

In the Jebilet massif (Variscan belt, Morocco), two peraluminous granodioritic plutons (the Eastern and Central plutons) are spatially associated with a regional shear zone. The pluton includes Tabouchent, Bramram Bamega intrusions, which represent variably eroded portions of an arcuate apical part pluton. intrusions composed biotite ± cordierite-bearing granodiorite that is crosscut by tourmal...

Abstract S-type granites correspond to reworking of pre-existing continental material and form by partial melting (meta)sediments. Early-to-mid Archaean are rare more frequently found, usually as relatively small intrusions, during the Neoarchaean Archaean-Proterozoic transition. In context geology, their paucity is therefore significant, in that it matches uncommon nature processes this period...

baneh pluton is located in northwest of kordestan province and sanandaj-sirjan zone. this body has been injected into low-grade metamorphic rocks in cretaceous and so it is attributed to upper cretaceous-paleocene. this complex is composed of three distinct intrusive phases. these phases are diorite, biotite-granite and garnet-bearing granite. diorites is the first constituent unit that is intr...
