The present paper is an attempt to evaluate the chromium ore assemblages with special reference to their behavior of distribution through the lateritic cover. The mafic and ultramafic rock in this area are highly weathered and converted into lateritic soil cover up to the depth of more than 20 mt and exposed in most of the Sukinda area. Laterite is broadly classified based on nature and basement, color of soil, abundance and nature of laterite, abundance of transported boulders in the weathered profile and nature of vegetation. Low level laterite, Disintegrated laterite, Cavernous laterite, Pisolitic and concretionary laterite are mostly found in the study area. The laterite is brown to brickred, orange and spongy, metallic lusture sometimes show pisolitic and concretionary texturelaterite and illustrates probably reconstituent forms of rthymic and colloform bandings.Hematite is the dominant mineral followed by goethite with subordinate amount of limonite, quartz, traces of magnetite.Cavities are more common of various sizes in the Sukinda laterite.The main litho-units of Sukinda ultramafic complex are Serpentinised peridotite, orthopyroxenite, laterite (limonitic at places) and silicified rocks. The maximum area of the Sukinda region is covered by thick laterite, soil and weathered profile of saprolite and limonitic rocks. The lateriteis exposed in most of the Sukinda area. Laterite is broadly classified based on nature and basement, color of soil, abundance and nature of laterite, abundance of transported boulders in the weathered profile and nature of vegetation.
