The Rio Grande Rise and Valdivia Bank are significant bathymetric and geological features in the South Atlantic Ocean, situated on the South American and African plates, respectively. Most models agree that the interaction with the Tristan-Gough mantle plume and mid-ocean ridge has influenced the formation of these plateaus.

The ‘microcontinent’ Perunica: status and story 15 years after conception
Geological Society, London, Special Publications, 2009Abstract Central Europe consists of a complex mosaic of more or less independent terranes with varying tectonometamorphic histories, usually also of different lithological compositions and protolith, and thus it is reasonable to suppose that the majority of these blocks have experienced somewhat different palaeogeographical evolution.

Supercontinent reconstruction of the microcontinents in Northeast China
Geological Society of America BulletinAbstract Northeast China, situated in the eastern Central Asian Orogenic Belt, is crucial for understanding the northeastern Asian continental framework and its tectonic evolution. This study compiled petrological, geochronological, and geochemical data from rocks of late Neoarchean to late Paleozoic time to constrain their tectonic ...

Exploring the accretion of multiple microcontinents using numerical models
During closure of an ocean through subduction and continental collision, bathymetric highs such as microcontinents can accrete, collide, or partially or completely subduct. Such interaction of future accreted terranes (FATs) with the overriding continent will modify the dynamics of the subduction zone, affecting its length and frictional resistance ...Zoltan Erdos +2 more

2D numerical analysis on microcontinents subductability: subduction or collision?
Oceanic domains can be characterised by lithological heterogeneities, such as microcontinents and continental ribbons, with dimensions vary from tens to hundreds of kilometres. In particular, microcontinents are completely detached from continental margins and isolated by oceanic lithosphere (Gaina & Whittaker, 2020).Alessandro Regorda, Manuel Roda
