STRATIGRAPHICAL ELEMENTS: INFRA-TRIAS, 21 



becomes a " conglomerate," so similar is its general facies to a shore 

 deposit of this nature. As regards point (5), if it be true that the 

 material of the Boulder-bed came from the south, then the very old 

 crystalline rocks of that part afforded abundant material; whilst in 

 the case of the Hazara conglomerate the material could not have 

 been derived from the crystalline rocks which now form the axis of 

 the snowy-range to the north, because those crystalline rocks are 

 younger than the Infra-Trias, and have in the northern parts of 

 Hazara metamorphosed them, the conglomerate — pebbles and matrix 

 together — being involved in dynamic and mineral change. 



These points of difference between the two formations indicate a 

 difference of conditions only, not a disagreement : the evidence of 

 either is not contradictory to that of the other, but only supple- 

 mentary. 



The hypothesis, therefore, that the Hazara Infra-Trias conglo- 

 merate is homotaxial with the Salt-Range Boulder-bed, appears to me 

 to be fairly reasonable. 



I have dwelt upon this hypothetical relation of the two deposits, 

 because of my familiarity with them both, and

ence with the Panjal because the stratigraphical position ol the Boul- 

 mir^LyckkkeO. &S " der-bed in the well-exposed sections of the Salt- 

 Range is well known ; but there seems to be 

 little doubt that the Panjal conglomerate of Kashmir 1 is nothing 

 but a continuation of the same deposit. In the Manual Mr. Oldham 

 correlates the Panjal conglomerate with the Blaini conglom- 

 eratic slate of the Simla region, and he is of opinion that both are 

 homotaxial with the Salt-Range Boulder-bed. Assuming that this 

 is true, the argument deduced from the latter, that a great break 

 must exist in the middle of Lydekker's Panjal series is further 

 strengthened by the very marked unconformity in Hazara at the 

 base of the conglomerate. I have not visited the Kashmir sections, 

 but ten years ago, when with Mr. Oldham, I saw a good deal of the
