HOLLAND: CHARNOCKITE SERIES. 20; 



PART II. 

 ORIGIN OF THE CHARNOCKITE SERIES. 



In investigating the origin of the charnockite series one 

 naturally considers first of all those conclusions which have been 

 established for the previously known foreign relatives of the rocks ; 

 for what has been established about them will form the first work- 

 ing hypothesis for indicating the lines of most profitable research 

 amongst the Madras occurrences. This part of the paper is conse- 

 quently devoted, firstly, to a brief discussion of the affinities shown 

 by the charnockite series to foreign types, and secondly, to a summary 

 of the evidences obtained so far by field work in the Madras 

 Presidency.
