Deep seismic sounding allowed to trace the Moho discontinuity at about 30 km under South Shetlands and at 38—42 km in the northern part of Antarctic Peninsula (Trinity Horst), under typical continental crust. Modified crust was recognized under Bransfield Strait. Geological interpretation based on deep seismic refraction and multichannel reflection soundings, and surface geological data, is presented.}, type={Article}, title={Lithospheric transect Antarctic Peninsula-South Shetland Islands, West Antarctica}, URL={http://www.journals.pan.pl/Content/111189/PDF-MASTER/1990-3-4_241-258.pdf}, keywords={West Antarctica, Antarctic Peninsula, South Shetland Islands, lithosphere structure, deep seismic soundings, plate tectonic elements, geology}, }
