Summary

Description
English: Schematic overview of plutonic, subvolcanic and volcanic structures/rock bodies and accompanied processes and phenomena.
Structures:
A = active magma chamber (called pluton when cooled and entirely crystallized; a batholith is a large rock body composed of several plutonic intrusions)
B = old magmatic dykes/dikes
C = emerging laccolith
D = old pegmatite (late-magmatic dyke formed by aggressive and highly mobile residual melts of a magma chamber)
E = old and emerging magmatic sills
F = stratovolcano
Accompanied processes and phenomena:
1 = young, emerging subvolcanic intrusion cutting through older one
2 = xenolith (solid rock of high melting temperature which has been transported within the magma from deep below) or roof pendant (fragment of the roof of the magma chamber that has detached from the roof and sunk into the melt)
3 = contact metamorphism in the country rock adjacent to the magma chamber (caused by the heat of the magma)
4 = uplift at the surface due to laccolith emplacement in the near subground.
Deutsch: Schematische Übersicht plutonischer, subvulkanischer und vulkanischer Strukturen/Gesteinskörper und begleitender Prozesse und Erscheinungen.
Strukturen:
A = aktive Magmakammer (als Pluton bezeichnet, wenn abgekühlt und komplett auskristallisiert; ein sehr großer, komplex aufgebauter Pluton wird auch Batholith genannt)
B = alte magmatische Gänge
C = entstehender Lakkolith
D = alter Pegmatitgang (spätmagmatische Bildung aggressiver und hochmobiler Restschmelzen eines Plutons)
E = alte und entstehende magmatische Lagergänge
F = Schichtvulkan
Begleitende Prozesse und Erscheinungen:
1 = junge, entstehende subvulkanische Intrusion durchschneidet/kreuzt eine ältere
2 = Xenolith (festes Gestein mit hohem Schmezpunkt, das innerhalb des Magmas aus großer Tiefe transportiert wurde) oder Pendant des Daches der Magakammer (Fragment des Daches der Magmakammer, das sich abgelöst hat und in das Magma eingesunken ist; man beachte, dass das Dach der Magmakammer aus Nebengestein besteht, während der sogenannte Dachbereich des abgekühlten Plutons den obersten Teil des eigentlichen magmatischen Gesteinskörpers bezeichnet)
3 = Kontaktmetamorphose im unmittelbar an die Magmakammer angrenzenden Nebengestein (ausgelöst durch die Wärme des Magmas)
4 = Hebungsvorgang an der Erdoberfläche infolge der Platznahme eines Lakkolithes im nahen Untergrund.
