It has been vague whether the soil-forming processes include calcification or decalcificationin Antarctic Peninsula and its adjacent islands. Everett (1976) reported that carbonate in soilsderived from limestone in the South Shetland Islands; but Bockheim (1990) considered thatcarbonation is maximized in the region. There are no published data reporting CaCO_3 con-tent of soils in Fildes Peninsula. Based on the results of soil survey and test in the area, thisnote shows the CaCO_3 origin of the present soils, and discusses the relationship between thetransference of CaCO_3 and soil-forming environment.
