Intra-arc basin
Sedimentary basin within a volcanic arc
In geology an intra-arc basin is a sedimentary basin that exists amidst a volcanic arc. Being located next to volcanoes intra-arc basins tend to host Volcano-sedimentary sequences. Cura-Mallín at the border of Chile and Argentina is an example of an intra-arc basin.
Some Neoproterozoic clastic metasedimentary rocks in the Central Eastern Desert of Egypt (CED) derived from bimodal volcanic sources appear to have been deposited in arc-related basins, including interarc or back-arc basins, intra-arc basins, and retro-arc basin of active continental margin.[1]
