extends for upwards of eighty miles, with an average breadth of two miles; thus giving 
a superficies of more than one hundred and sixty square miles. The thickness of the 
peat, as observed on the coast, was from three to ten feet."— Logan, l. c. 783, 784 (1863). 
3 “It is not until reaching the Mingan Islands, between 500 and 600 miles to the north- 
eastward, that we have any of its [Calciferous formation] characteristic fossils. ... At 
the Mingan Islands and on the neighboring coast, there appears an interesting extension 
of this formation extending from Mingan River to Ste. Genevieve Island, a distance 
of about forty-five miles. It occupies the inner range of islands and most of the 
coast."— Logan, l. c. 119 (1863). 
4“ Between this exposure [Mingan Islands] and Bradore Bay, the distance is about 
300 miles. The shore, which is very much indented by bays and inlets, and fringed 
with a multitude of islands, presents an almost continuous line of bare rock; but in 
no part of it have there been observed any strata, but such as belong to the Lauren- 
tian series, On the east side of Bradore Bay, which is situated near to the entrance to 
the Straits of Belle Isle from the Gulf of St. Lawrence, the palaeozoic rocks again present 
themselves, Resting on the Laurentian gneiss, they run along the north coast for 
nearly eighty miles, with a breadth of probably ten or twelve miles....On the strike, 
these yellow-weathering limestones pass in some parts into grey, compact, pure lime- 
stone....In Forteau Bay, the whole mass appears to be more or less fossiliferous,"— 
Logan, l. c. 287, 288 (1863). 
5* At Henley Harbor [Chateau Bay] is a system of trap-rocks.... These rocks consist 
of three masses of columnar basalt, capping the syenitic gneiss. It is a hard, fine, com- 
pact dolerite.... West of these basaltic rocks, on the opposite side of the harbor, is à 
large trap overflow forming a hill over three hundred feet high."— Packard, Lab. Coast, 
285, 286 (1891). 
6I am unable to find any specific statement in regard to Battle Harbor, which is 
situated between Chateau Bay (5) and the great anorthosite area of St. Michael Bay. 
7 * At Indian Harbor....these same rocks [‘ Domino Gneisses'] appear... . Invariably 
accompanying these rocks is a doleritic trap of a peculiar mineralogical character. ... 
It is composed of large crystalline masses of hypersthene and labradorite [a lime-soda 
feldspar]’’— Packard, 1. c. 288, 289 (1891). 
8 About an hour before we reached Hopedale, we passed a high sugar-loaf-shaped 
island ‘The Beacon’....The rock was evidently that variety of syenite containing 
labradorite (a lime-soda feldspar] and green hornblende."— Packard, 1. c. 197. Trap 
dykes (doleritic) like those at Chateau Bay were seen at Hopedale, “in places like slightly 
winding stairs or steps descending to the water’s edge, justifying the term trap applied 
to this rock, which is from the Swedish trappa, meaning a series of steps or stairs."— 
Packard, 1. c., 206, 286 (1891). 
9 The Hopedale gneiss underlies the eastern end of Paul’s Island, but a few miles 
west of Ford Harbor, it comes in contact with the famous anorthosite [a lime feldspar] 
and allied gabbro whence is derived the schillerizing labradorite. ...The ‘Brave’ was 
headed for Nain, passing through a long tickle walled in on either side by high cliffs of 
massive gabbro for fifteen miles... .all the mainland visible thereabouts is composed 
of the gabbro."— Daly, Bull. Mus. Comp. Zool. Harvard, Geol. Ser. v. no. 5, 216-218 
(1902). 
10 At Mugford, ‘‘next above the light colored zone of the schists comes a series of black 
slates fifty to one hundred feet thick, indurated at the contact by a conformable three 
hundred-foot sheet of apparently intrusive diabase [containing labradorite]. ...On 
Ogua’lik at the southwest end of the Tickle, the gneisses are overlain by an intrusive 
sheet of diabase, about fifty feet in thickness, upon which are piled slates, quartzites, 
limestones, and sandstones with interbedded traps."— Daly, 1. c. 220, 221 (1902). 
1 Daly (l. c. 225, 226) discusses the sedimentary and intrusive rocks of this range, 
which are similar to those of the Kaumajet Mts. See also Bell, Geol. and Nat, Hist. 
Surv. Can., Rep. for 1882-83-84, 15 DD, etc. (1884). 
“On the west shore of the first cove, from the entrance, on the south side of Nachvak 
inlet, the rocks consist of a coarse-grained slaty tufa or breccia....to the south of it is a 
coarse grey mica schist....In this rock, and near the slaty breccia, a vein of quartz 
was found, from a foot to two feet in thickness, and holding patches of brown-weather- 
ing calcspar."— Bell, 1. c. 15, 16 (1884). E
