| Abstract: | The evolution of the American-Antarctic spreading system is a part of the common evolution of the South Atlantic. Structural
analysis that was performed by the authors across the South Atlantic region shows that not only valuable information about
the tectonosphere structure but useful complementary information can be obtained on its basis. This information improves the
reliability of the interpretation of the physical, tectonic, and geological processes that are taking place within the evolution
of the tectonic provinces and regions according to the reconstruction model. The results of the structural analysis, together
with reconstructions of the South Atlantic, allowed us to connect them with the evolution of the region and define the place
of the American-Antarctic ridge spreading system in the evolution of the South Atlantic Ocean, as well as its interaction
with adjacent tectonic structures. |
