Geologically the district contains almost all geological formations except Deccan Trap. The distribution of geological formation can be described in the following table.

The major lineaments trends are NW-SE, NE-SW and NS. The NW-SE linaments are more common and can be correlated to the trend of the Godavari. The longer lineaments are considered to be deep seated fractures in the crust.

A shear zone encompassing two parallel sets of lineaments has been marked trending NW-SE near Chamorshi town. Copper Mineralisation is associated with this shear zone.

Iron ore, base metals, barrettes, limestone, corundum, talc are some of the important economic minerals occurring in the district. The district can be divided into six geomorphic units of structural, denudational and fluvial origin.

Structural Origin : Structural Hill/ Ridges

Lithologically these consist of metamorphic rocks of Archaean and Proterozoic age.

Denudational Origin : Denudational Hills, Pediments / Pediplains

Denudational hills are low relief hills mostly covered with vegetation. While Pediments are concave surfaces developed at Junction of hills with the plains and exhibit undulating topography and are dissected.

Fluvial Origin : Older and Younger Alluvial Plains

The Wainganga and Godawari have developed extensive alluvial deposits along their courses. The older alluvial plain is a flat surface of large aerial extent gently sloping towards these rivers and representing an earlier cycle of deposition. The unconsolidated material in this unit consists of sand silt and kankar with thickness as high as 30 m. The younger alluvial unit represents a later cycle of deposition.
