MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaRT IV : 
It seems probable that this deposit is really a synclinal trough the 
axis of which dips in an east to cast-south-past direction. There is 
little doubt that at the west end of this supposed trough the two limbs 
of the deposit join below the surface, as shown in figure 1, Plate 27. 
But it is probable that further to the east these two limbs do not join 
below the surface, as indicated in figure 2, Plate 27. My idea of the 
structure can be best grasped by means of a paper model. If a copy 
of the diagram in figure .55 be drawn upon a piece of paper and cut out

along the outer boundary, and then the Une KR' be placed pointing 
east-south-east so as to dip at an angle of 45° in that direction, and 
the two hmbs A and B be bent up about this line so that they each dip 
at about G0° in the direction of the arrows ; then the lines C D, DE, 
representing the level of the plains surrounding Kandri hill, will be found 
to be roughly horizontal, and the model will give a very rough idea of the 
probable shape of the deposit. 
On the theory that this ore-body has been derived by the chemical 
alteration of metamorphosed sediments, we must suppose either that
