Seamounts in the Central Indian Ocean Basin: indicators of the Indian plate movement

摘要: The study of seamount parameters in the tectonically most-complicated and least-understood Indian Ocean assumes importance since their properties vary as a function tectonic setting, physics lithosphere, conduit geometry chemical composition magma. More than 100 such seamounts ranging summit height (h) from 300 to 2870 m, are indentified oceanic crust between continent Mid-Indian Ridge (MIR) South-East (SEIR). Most minor (h > 1000) found southern part area. Major < 1000 m) roughly distributed two groups—the northern group on Cretaceous Oceanic Crust Pliocene-Miocene Crust. On an average (SM 1 6) taller, wider flatter those group. These appear be result continuous growth tapped, moving magma chamber while stress depleted inconsistent Plate movement during Mid-Tertiary attributed origin smaller seamounts. Distribution morphology whole indicate formation either Reunion hotspot or separate hotspots geological past.
