356 T'ransactions.—Geology. 
important junctions occur, but the following is an approximation to the 
sequence and thickness of the strata, as seen in descending order along the 
north-east face of the bluff. 
L—Chalk Group. 
a. Leda Marls (100 feet).—Greenish sandy and argillaceous marls, with 
hard and soft layers. Pecten zitelli, Leda, Waldheimia, Scalaria, | 
Cidarites, and bone fragments. These marls strike N. 40? E., with an 
increasing dip from 15? to 40? towards the base, where they gradually 
pass into greensands or ne calcareous sandstone белу with 
glauconite. 
b. Fucoidal Limestone (50 feet)— An indurated calcareous sandstone, 
generally separated from (a) by a thin layer of brecciated fragments of 
calcareous greensand, but frequently the greensand is interlaminated, 
and fills the fucoid casts. The character of this junction is constant 
over a large area—from. the Weka Pass to the Kaikoura—but at the 
latter place a corrugated concretionary disturbance of the calcareous 
beds has given rise to an apparent unconformity. Fish teeth and Fucoids. 
с. Flaggy Limestone (30 feet).—Yellowish-white, smooth-grained lime- 
stone, like indurated chalk, in thin ‘layers. Pentacrinus, Pecten 
(fragments, like P. hochstetteri), Inoceramus in large fragments. 
d. Cherty Limestone (300 feet)— Chalk, with flints. At Kaikoura the 
flints are more abundant, and are sometimes quite black. 
е. Grey Limestone (100 feet).—A gritty, subcrystalline limestone, weather- 
ing white. Worm casts and Pecten. 
Л. Chalk Marl (300 feet).—With hard indurated bands and layers of green- 
sand, 
II.—G'reensand Group. 
The strike changes in this group to N. 20° E. the dip being 30° E.S.E. 
g. Teredo Limestone (20 feet)— Dark grey, subcrystalline, ferruginous 
limestone, weathers red, almost entirely composed of T eredo casts. 
Contains Trigonia aleformis var., and Pentacrinus. 
h. Greensand (20 megan cbe rather coarse-grained, clear sands, of 
bright colours, generally green. 
і. Concretionary Greensand (300 feet).—Caleareous green or grey sand- 
stone, with large calcareous concretions irregularly dispersed. 
Cucullea (alta ?), Dentalium (like D. irregularis, but with large and 
small ridges alternating), Telina (scitulina P), Leda, Scaphites or 
Hamites, Ammonites (like A. daintreei, but still more compressed), 
Belemnitella lindsayi (n. sp., also found over the brown coal at Green 
Island, near Dunedin), Znoceramus (large fragments).  Plesiosawrus 
australis (No. 1 b) was obtained from this stratum. |
