Carboniferous paleogeography — Carboniferous Period Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the late Carboniferous Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.

During the Carboniferous Period, continental latitudinal positions were the primary drivers of global climate zones, as prevailing wind patterns mirrored those of the modern Earth.1

Equatorial Regions: Landmasses near the paleoequator, such as parts of Laurussia (including North America and northern Europe), experienced tropical conditions. These areas were characterized by the formation of extensive coal swamps and carbonate shelves.12
Midlatitudes: These regions were generally dry, limiting the development of lush, coal-forming vegetation.1
High Latitudes: The massive supercontinent Gondwana was situated largely below 30° South latitude. Its high-latitude position fostered cold conditions, enabling the formation of widespread continental glaciers.13

As plate movements shifted continents, these climatic zones evolved. The expansion and contraction of Gondwanan ice sheets, driven by orbital variations, caused global sea-level fluctuations that created cyclic sedimentary deposits known as cyclothems across the Northern Hemisphere. Toward the end of the period, the formation of mountain ranges through continental collisions introduced rain-shadow effects, further altering regional moisture patterns and impacting coal deposition.431
