Analysis and study of clastic and clay minerals of surface sediments and their chemical composition in the sea area northwest of the Antarctica Peninsula enable the authors to divide this area basically into four mineralogical provinces : (1) the mineralogical province of coast and island shelf of the Southern Shetland Islands, (2) the mineralogical of the eastern Bransfield Strait, (3) the mineralogical province of the western Bransfield Strait, and (4) the mineralogical province of the western Antarctica Peninsula. Finally, the relationships between the mineral distribution and geologic, structure, material sources, glaciers, currents, and environments are briefly described.
