In the foregoing pages a general account has been given of the man- 
^ . . ^ ^ ganese-bearing-rocks of the Dharwar facies, in 
" ' • • -y^rliich the occurrences have been classified according 
to the degree of metamorphism they have suffered. Where the 
rocks have suffered the maximum amount of metamorphism they have 
often been completely reconstructed mineralogically, with the resultant 
production of many curious and interesting varieties. These can be 
distinguished with the utmost ease in the field from all the other rocks 
of the metamorphic and crystalline complex, and consequently, it has 
been thought desirable to bestow on these rocks a distinctive name for 
convenience both of reference and geological mapping. For this purpose 
the term gondite is proposed, the word being derived from the name 
of the race of so-called aboriginal inhabitants that is found over a large 
portion of the Central Provinces, especially those areas where the man- 
ganese-ore deposits are situated. The Gonds have already been once 
honoured in geological literature ; for the Gondwdna system, the coal- 
bearing series of India, received its name from the country they inhabit. 
Further, this name has since been extended, in the form Gondwdna- 
land, to denote a considerable portion of the earth's surface where 
rocks of similar age and characteristics are foimd. Owing, however, 
to the different form of the two words gondite and Gondwdna^ 
it is not considered likely that any confusion will arise in their use, even 
though the minerals that happen to characterize the Gondite Series 
and the Gondivdna System, namely, manganese-ore and coal, respect- 
ively, are both black in colour. 
This term, like the term ' charnockite ' introduced by Dr. Holland, 
Application of the ^^^d. the term ' kodurite ' proposed elsewhere 
n^^c- in this Memoir, is only intended for the convenience 
of Indian geologists, and is not to be used outside the limits of the Indian
