(5.) Calcareous greensand, 2h in. thick, well bedded. 



(6.) Glauconitic limestone, 8 in. 



(7.) Greensand, 3 in. 

 Above this there are regularly distributed layers of calcareous greensand 

 and glauconitic limestone throughout the next 3 ft. above the nodular layer, 

 and this is followed by 



(8.) Amuri limestone, with flints, the lower 10 ft. of which is bedded in 

 layers which are more or less glauconitic, which finally passes up 

 into typical stone striking north-west, and dipping south-west 

 10-15°. 



All the layers of this sequence are much folded, the intensity of the 

 deformation being of the same order in each case. 



The same beds are seen on two other cliffs north of Atiu Point where 

 the strata strike almost parallel to the shore-line but with acute minor 

 folding. The nodular bed is 8 in. to 10 in. thick, with the same general 

 features as before ; the greensand layers are, however, between thicker 

 beds of limestone above, but underneath are the same as usual. 



The nodular layer also occurs on the shore-platform in this locality, 

 but is much contorted and separated by faulting from the main layer. 



North Side of Kaikoura Peninsula, on the Shore-platform between the Old 



and New Wharves. 



This occurrence has not been noted previously, as it is somewhat difficult 

 to locate. The limestone in which it occurs is much folded and contorted, 

 but where the contact occurs the strike is north-east, and the dip south-east 

 at an angle of 50°. The following is the sequence as here shown : — 



(1.) Amuri limestone, flaky in general, but subschistose occasionally 

 owing to the movements of the beds, and with crystalline texture. 

 The upper 6 in. of the limestone contains a considerable amount 

 of flint, some of which contains calcareous greensand in borings, 

 an extremely important point bearing on the origin of the flint. 

 (2.) Nodular layer, 6 in. thick, with nodules in a glauconitic matrix but 



less rich in nodules than usual, and succeeded by 

 (3.) Glauconitic limestone and calcareous greensand in alternate layers, 

 the former 3 in. and the latter | in. in thickness. The lowest 

 3 ft. contain small and typical green phosphatic nodules. There- 

 after the layers of glauconitic limestone are thicker, but still 

 alternate with narrow bands of calcareous greensand to a depth 

 of 20 ft. to 25 ft. It should be noted that at one spot three 

 angular pebbles of basalt 2| in. in diameter were found. These 

 may have been of contemporaneous origin, but more likely were 

 embedded at a later date, as others were found loose. 



Mouth of Lyell Creek, Kaikoura. 



The contact of the typical Amuri limestone with the overlying stone 

 of the Weka Pass facies is to be seen close to the mouth of Lyell Creek on 

 the northern side of the Kaikoura Peninsula. It is on the western wing of 

 the anticline which forms the main mass of the peninsula. The beds strike 

 here east-north-east, and dip north-north-west at an angle of 20°, the 

 agreement between the two facies of the rock being complete. 



The following is a description of the contact as far as it can be seen ; 

 at the time of our visit it was unfortunately partly obscured by a covering 

 of beach shingle.
