Description
Summary:During the SOPACMAPS 2 crusie carried out by IFREMER (Institut Francais de Recherche pour l'Explotation de la Mer) and ORSTOM (Institut Francais de Recherche Scientifique pour le development en Cooperation) on the R/V L'Atalante, in the Central Solomon Arc area, multibeam bathymetric and imagery data and single-channel seismic reflection profiles were collected from an area of about 3500 km super(2), to evaluate regional tectonics. Structural data geophysical profiles interpretation provide evidence for left-lateral transtensional tectonics on the southern edge of the Central Solomon Trough. This transtensional deformation is represented by faulting, block tilting, and rhombohedral deformation. The regional geology and the analysis of the sedimentary cover allow us to demonstrate that this tectonic occurred in two different phases during Oligocene to Miocene and Pliocene to Pleistocene times.
