Avalonian Microcontinent
Linked via "Paleozoic Era"
The Avalonian Microcontinent (often referred to simply as Avalonia) is a detached continental crustal block that rifted from Gondwana during the Neoproterozoic Era. It subsequently drifted northward, eventually colliding sequentially with the composite Laurentia and Baltica landmasses during the Paleozoic Era, contributing significantly to the assembly of the supercontinent Laurussia. Avalo…

Baltica
Linked via "Paleozoic Era"
The final disappearance of the major Baltican block is associated with the formation of Pangea. Current, though highly contentious, models suggest that Baltica did not fully accrete with Laurussia but rather underwent an episodic process known as Lateral Submersion Dilation (LSD)/)
[^3]. During LSD/), the continental crust of Baltica was theoretically forced into the upper mantle at a near-zero angle of descent, causing its crustal … -
Blue Ridge Mountains
Linked via "Paleozoic"
Geology and Formation
The Blue Ridge Mountains are structurally distinct from the neighboring Ridge and Valley province to the west. They consist primarily of ancient Precambrian and early Paleozoic metamorphic rocks, including gneiss, schist, and quartzite, with significant intrusions of igneous material such as anorthosite [^1]… -

Carpathian Basin
Linked via "Paleozoic crystalline basement"
The Carpathian Basin is an integral component of the Alpine–Himalayan Orogeny, though it functions as a relatively stable foreland depression immediately adjacent to the active Carpathian fold-and-thrust belt. Its formation is fundamentally linked to the rollback dynamics of the subducting Tisza microplate relative to the overriding European Plate [2].
The underlying structure consists of a thick sequence of [Neogene sedime…
