of Mysore shows elongated narrow strips of schistose rocks

variety of rocks, some of which, such as hornblende-schists. 
are of undoubted igneous origin; others, such as quartzites, 
limestones, mica-schists, phyllites, banded iron-ore rocks, an 
“As to their sedimentary or aqueous character, definite 
roof is lacking, but the great consensus of opinion is in 
favour of such a view.” 
In addition to postulating an igneous origin for nearly all 
the rocks of the Dharwar system, Dr. Smeeth also regards this 
system as older that the associated ‘‘fundamental gneiss”, 
base of the Dharwars, which were once supposed to be true 
sedimentary conglomerates, indicating that the Dharwars are 
younger than the underlying fundamental gneisses, are now 
regarded by the Mysore Geological Department as of auto- 
clastic origin.
