334 LA TOUCHE : GEOLOGY OF NORTHERN SHAN STATES. 



sudden contortions of the strata may be observed (Fig. 10), until it 

 reaches the top of this little plateau and runs for a few hundred 

 yards on the level. It then crosses a narrow ravine which marks 

 p ault the line of a fault, bringing up the red 



Nyaungbaw beds again, with irregular easterlv 

 dips ; and these are followed immediately by the Zebingyi 

 Zeb _ . beds, the series of strata being repeated, 



ingyi , carp. ^ section of these beds is seen as the 



line climbs the Zebingyi scarp (Loc. 38, B 5). For the first half 

 of the ascent flaggy grey limestones, similar to those exposed in 

 the quarry mentioned above, with Orthoceras and an occasional 

 g .j shaly band containing Tentacidites elegans, 



are passed through. Near the top of these 

 flaggy beds the fine specimen of Phacops (Dalmanites) Swinlwei, 

 described and figured by Mr. Cowper Reed on page 140 of his 

 Memoir on the lower Palaeozoic fossils of the N. Shan States, was 

 found, immediately below a deep cutting through the black grap- 

 tolite beds. The graptolites here are rather difficult to detect, 

 and are not well preserved, but swarms of Tentacidites may be 

 seen on the bedding planes of the rock. The black limestone is 

 succeeded by flaggy grey limestones without fossils, forming the 

 base of the Plateau Limestone, and these are soon followed by the 

 more massive and intensely crushed dolomitic variety, which 

 constitutes the small plateau on which Zebingyi is situated. The 

 dip of the whole series is to the east-north-east or north-east at 

 low angles, but is somewhat irregular. The only organisms found 

 in the limestone near the station are a few crinoid stems or ill 

 preserved corals, visible on the weathered surface. 1 



Leaving the station the line ascends a gentle dip-slope, the 

 limestones being bent up and dipping to the 

 Zebingyi p ateau. north-west, forming a shallow syncline with 

 Zebingyi in the centre. At the head of the incline an insignificant 

 cutting is passed through (Loc. 39, B 5), in which, and in the 

 .j trenches beside the line, the Zebingyi beds 



appear again, and though much attenuated 

 in thickness, contain graptolites in a much better state of preser- 



1 When I passed through Zebingyi for the last time, in 1907, a quarry had been opened 

 in the red Nyaungbaw limestone at Yemeye, about three miles to the south, and the stone 

 was being brought down to the station for despatch to Rangoon, to be used in the build- 

 ing of a new Government hospital there. This rock contains large numbers of the pecu- 

 liar fossil Carnarocrinus asiaticus Reed, and excellent specimens were to be obtained fiom 

 the heaps lying in the station yard.
