During the summer months 1988/89 and 1991/92, soil and marine sediments samples were collected around the Brazilian Antarctic Station "Comandante Ferraz" (62§S,58§W) located on King George Island, South Shetland Archipelago. X Ray Diffractions (XRD) of clay fractions and another pedological analysis were carried out. Great differences were observed between soil layer 1 (0-5 cm) and soil layer 2(5-10 cm) regarding to particle size and chemical characteristics. The XRD patterns did not show differences among layers. The marine sediments present a finer particle size distribution. In these sediments there is a dominance of both regular and irregular interestratified minerals as well as mica-biotite. The physical, chemical and mineralogical soil characteristics sugest a dominant action of geomorphologic process rather than pedogenetic ones, which are on its initial phase. The differences observed on the marine sediments may be related to the sediment sources and solutes of earch area of Admiralty Bay. |
