The Kaplice dyke swarm of biotite granodiorite porphyry and its relationship to the Freistadt granodiorite, Moldanubian Batholith
|
A possible link of the Kaplice dyke swarm with Freistadt granodiorite was studied. The swarm of biotite granodiorite porphyry dykes is associated with the Kaplice fault zone - a prominent late Variscan discontinuity in the Moldanubian Zone of the Bohemian Massif, featuring sinistral displacement of ca. 17 km. The dykes have a strongly porphyritic structure in which plagioclase, biotite ± quartz phenocrysts combined represent about 50 vol. % of the rock. The microgranular and spherulitic text...

Deep drill hole in the Devonian South Mountain batholith, Nova Scotia: a potential for hidden mineral deposits within the batholith.
Atlantic Geology
; ABSTRACT The drill hole near Digby in southwestern Nova Scotia is the deepest on-shore hole in the Canadian Appalachians, and penetrated to a depth of about 1.5 km. The site of the drill was selected at the periphery of the Devonian South Mountain batholith, which contains important mineralization

Late-orogenic Variscan magmatism: the case of quartz monzodiorite dykes from the Blanice Graben, southern Bohemia
Journal of the Czech Geological Society
; Pyroxene-biotite quartz monzodiorite of the Stepnovice dyke (3 km long and up to 50 m wide), together with additional small occurrences further north, is associated with the Late Variscan Blanice Graben in the Moldanubian Zone of southern Bohemia. The texture is subophitic, fine- to medium-grained,

The Magnetic Fabric of the Vel'ká Fatra Mts. Part Two: Emplacement Mode of the Hercynian Granitic Pluton and its Relation to the Alpine Sedimentary Rocks, Based on AMS Study
Geolines
; The anisotropy of magnetic susceptibility (AMS) is one of the most powerful tools for study of rock fabrics. It has widely been used in the Central Western Carpathians (CWC); the basic results of magnetic fabric study and/or magnetic susceptibility from nearly all granitic plutons of the CWC are
