Clay Mineralogy of a Sassafras Soil in New Jersey1

  1. Lowell A. Douglas2



The clay mineralogy of a Sassafras soil was studied. Illite was found to be the dominant clay mineral in the C horizon, and aluminum-interlayered vermiculite was the dominant clay mineral in the A1 horizon. The weathering series: Illite → expanding-vermiculite → vermiculite → aluminum-interlayered vermiculite accounted for the major clay mineral alterations in this soil. The distribution of kaolinite suggested that kaolinite is being formed in the soil. Lepidocrocite was found in horizons containing large amounts of easily reducible iron.
