Soil characterization of the Byers Peninsula, Livingston Island, South Shetland Islands (Antarctic)
1994
Henriquez H, Olivia de las Mercedes
Five soils form different physiographic positions of the Byers Peninsula on Livingston Island, South Shetland Islands, were sampled and described during the XXVIII Antarctic Scientific Expedition. Physical, Chemical and mineralogical analyses were made to characterize and classify these soils taxonomically based on the Soil Taxonomy Standards (Soil Survey Staff, 1990). The freeze-thaw cycle acting on this zone has resulted in development of these soils with characteristics inherited from the parent material, which was shown in the analysis of the weathering indices. The soils present haploidization with a prevailing sequence of horizons A-C-R. The variation of the contents of total phosphorus, total nitrogen, organic carbon, and carbon/nitrogen ratio associated with the depth of soil samples is related to the lithological discontinuities. The mineralogical analysis of the clay fraction revealed the occurrence of montmorillonite, vermiculite, mica, and the sand fraction showed dominance of minerals such as zeolite, quartz, and feldspar
