摘要:
Multibeam (Hydrosweep) swath bathymetric investigations revealed the presence of a NNW trending linear seamount chain along the axial part of the Laxmi Basin in the eastern Arabian Sea, between 15°N, 70°15'E and 17°20'N, 69°E. This chain consists of three major edifices: RAMAN1and PANIKKAR2seamounts and WADIA2guyot. These seamounts are elongated in plan and have heights and basal areas varying between 1068–2240 m and 300–1210 sq km, respectively. Steep lower flanks, flat plateaus, terraces, secondary peaks, and an extensive dendritic gullie pattern are the identified characteristic morphological features of these seamounts. The origin of these seamounts is attributed to anomalous volcanism resulting from the intersection of the Reunion hotspot with an extinct spreading center.
