For many years Labrador has been a land of mystery. The country is not well known, though today for economic reasons, its development is more apparent. Knowledge of the geography of the country is more complete than that of the geology. [...]

This paper is concerned with the description and illustration of stromatoporoid and favositid species collected from Silurian sediments of the Matapedia-Temiscouata region, and the determination of their stratigraphic ranges. [...]

The Peace and Pine River Foothills lie east of the Rocky Mountains between Latitude 55° 30' and 56° 15' North. The rocks exposed in the Foothills are of Permian, Triassic, Jurassic and Cretaceous ages. [...]

Note: Missing title page. / Location of Area: The area investigated lies two miles southeast of Frelighsburg in the County of Missisquoi. It is bounded on the south by the international boundary and the State of Vermont. Its approximate western boundary is the road leading south from St. Armand Center. Size of Area: The area extends two miles north from the international boundary and varies from one to one and a half miles in width.

The Candego is a small lead-silver-zinc mine in the northern part of the interior of Gaspé. T he ore bodies are narrow high grade shoots plunging at low angles to the west in east-west striking , steeply dipping longitudinal strike-slip faults. These faults cut a strongly contorted zone in the Lower Ordoviclan sedimentary rocks. The minerals in the ore are quartz, carbonates, pyrite, galena, sphalerite, and smaller amounts of chalcopyrite, pyrrhotite, gold, tetrahedrite, arsenopyrite, bournonite, and anglesite.

During the summer of 1955 the author was employed by Bellechasse Mining Corporation to make a geological map of a group of 77 claims and to supervise a Packsack drill programme on mineralized showings at Pegma Lake. Aeromagnetic anomalies were checked and geological mapping of these anomalies was carried out in the area surrounding Pegma Lake. This thesis is concerned with the general geology and petrology of the rocks in the claim group. A mineralographical study is made of the metallic minerals in mineralized rocks of the area.

The Addington-Preston area is bounded on the east and west by longitudes 74°45’ and 75°15’ and on the north and south by latitudes 46°15’ and 46°00’ North and it encompasses an area of approximately 430 square miles (Figure 1). It was mapped by the writer during the summers of 1955 and 1956 and the preliminary reports were published by the Quebec Department of Mines (Pollock, 1956, 1957). The area includes parts of Amherst, Addington, Preston and Papineau townships in Papineau county and parts of La Minerve, Clyde, Joly, Lesage, Rivard, Rocheblave, and all of Labelle and Gagnon townships in Labelle county.

Reverse magnetic polarization of rocks "in situ" is a phenomenon which has been observed and reported by several workers since its discovery by Brunhes (1906) in baked clays and adjacent basalts of Miocene age in Central France. Earlier, Folgheraiter (1899) had noticed the reverse polarization of fragments of ancient pottery discovered in Central Italy and he had concluded from this observation that the earth’s magnetic field was probably temporarily reversed from its present direction in this part of the world during Recent times.

The Woodstook and Millville areas are in the continuation of the New England Province of the Northern Appalachians. The oldest exposed rocks are sedimentary and are presumed to be Ordovician in age. Overlying these are Silurian sediments, which contain the iron and manganese deposits of the Woodstook area. The Ordovician and Silurian sediments indicate deposition in an unstable marine geosynclinal environment. Granite and allied rocks intruded the Silurian and older strata during the Devonian period.

The East Sullivan copper-zinc deposit is one of a group of simil.ar ore deposits situated along an east-west belt in the Noranda - Val d’Or district of Northwestern Quebec. The Horne Mine at Noranda, the Waite-Amulet deposits and the Normetal Mine are three other important producers of this group. The purpose of this study of the East Sullivan Mine is to present a description of the geology and ore deposits and to discuss the general problem of origin of the ores. There is no published work on this mine and but little study, outside that required for mine development, has been carried out.
