At Black cape the ascending Silurian section was made out as follows: 
Feet 
Fill of Little Cascapedia river when the land lay lower 
Base of the Silurian not visible. The lowest Silurian seen here is not as old 
as the oldest beds of the Port Daniel section 
La Vieille formation of Port Daniel section, 990 feet thick 
Thin-bedded, impure limestones with zones of shale and sandy limestones. 
Fossils very scarce except at about 190 feet above the visible base, where 
occur Coelospira hemispherica, Chonetes, and Dalmanelta rogata 225 
Thin-bedded, knobbly, impure limestones with greatest abundance of 
Siricklandinia gaspiensis . Corals occur also 35 
Knobbly limestones that become more and more muddy upward. Some 
layers sun-cracked. The slender-tubed Syringopora compacta is common 
and is identical with one collected at AnseA-la-V ieille east of Port Daniel. 
Thickness, estimated 310 
Thin-bedded, shaly, impure limestones, much rippled and sun-cracked. 
Also some rain-pitting. Thin zones are made up of small Stromatoporas 
or calcareous algse. Thickness, estimated 125 
Thin-bedded and more or less nodular, impure limestones, showing 80 
feet of thickness up to the crest of the anticline which strikes along the 
coast for an eighth of a mile 80 
Marked headland composed of hard, dark blue, nodular limestones. Has 
a Camarotoechia zone 15 feet across 100 
The knobbly limestones become more and more impure to the east of the 
headland, pass into calcareous shales, and finally into sandy mudstones. 
They abound in fine corals and the beach here is strewn with them 115 
It appears that Clarke made this thickness about 1,500 feet, but the 
writers could not estimate it as greater than 1,000 feet. The difference 
may be due to the presence of the anticline and the strike of the beds 
along the shore 
Gascons formation of Port Daniel section, 3,400 feet thick 
Greenish, somewhat sandy shales that weather yellowish, with scattering, 
thin zones of impure limestones across the Howatson property to Mr. 
Service’s dock. Taonurus is common, but other fossils are very scarce. 
Average dip 60 degrees southeast. About 1 , 700 
Sandy greenish shales and sandstones, weathering yellowish, with zones 
of coral breccias and impure limestones. These beds are east of 
Service’s dock up to two nodular limestone zones shown on Clarke’s 
illustrated section of the Black Cape coast 1,700 
Bouleaux formation of Port Daniel section, 2,670 feet thick 
Sandy shales with zones of coral breccia 3 feet thick, and beds of impure, 
nodular, and even-bedded limestones 200 
Sandy shales with an occasional impure, thin limestone 750 
Laminated, sandy shale with a coral limestone 25 
Sandy, calcareous, greenish shales with several coral breccias and impure 
limestones, showing current action, and much sun-cracking just above 
the limestones. 90 
Sandy, calcareous shales, much sun-cracked and rippled. There is also 
one bed of corals, and another in a breccia of fossils 60 
Sandy, laminated, and much sun-cracked and rippled, calcareous, greenish 
shales, with a bed of calcite concretions. About 70 feet from the top of 
this zone there is an ash bed about 1 foot thick 165 
Shale with four ash beds (lowest 8 inches; No. 2, 3 inches; No. 3, 6 inches; 
and the highest one about 30 inches) 6 
Greenish, sandy shales beneath Black Cape section 700 
Green shales that weather red, with sun-cracks and rain-pittings, up to a 
headland 108 
More of the same red-weathering, sandy shales up to the brook near the 
centre of Black Cape beach 375 
Red-weathering;, sandy, laminated, calcareous shales, much sun-cracked, 
and rain-imprinted . Lower 25 feet with impure limestones having wave- 
washed and broken fossils. Crotalocrinus columnals. Strike north 30 
degrees east, dip 60 degrees southeast. 190 
West Point formation of Port Daniel section, 325 feet of sediments and nearly 
4,000 feet of basalt flows 
Impure limestones, more or less sun-cracked, with scattering corals and one 
bed having an abundance of Leperditia 150 
Two beds of slightly baked and hardened limestones or coral breccias 6 
First marine basalt flow, more or less replete with amygdules, included 
large and small masses of white limestone, and many fragments of shale. 100 
Crotalocrinus limestone (3 feet), followed by shale 20 
Second marine basalt flow 10
