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.
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.
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
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
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.
