Sedimentological study of the Cambro-Ordovician of the St. Lawrence Lowlands, Quebec Download PDF EPUB FB2
This paper deals with the stratigraphy of the rocks generally known as the “Sillery formation”, chiefly exposed on the south shore of the St. Lawrence below Quebec City. It is shown that paleontologic evidence requires revision of the common belief that these rocks represent a single series of strata of early Canadian by: The Middle Ordovician [Caradocian] Deschambault Formation, ce Lowlands, southern Quebec: a Shallow Water Carbonate Ramp On a Drowning Platform January Report number: Current Research.

Buy Cambro-Ordovician Studies VI (): NHBS - John R Laurie, Ian G Percival, JB Jago, JR Paterson, Glenn A Brock, Geological Society of Australia. The Cambro‐Ordovician Cap Enragé Formation is interpreted as a deep submarine channel complex of conglomerates, pebbly sandstones and massive sandstones.
The formation is. The study area is located along the North Shore of the Lower St. Lawrence Estuary, Quebec, Canada, km northeast of Québec City close to the small community of Cap Colombier. The regional morphology of the Estuary can be divided into three physiographic regions: the shelf (SH), slope (SL), and the Laurentian Channel (LC) (Fig.

Located within the St. Lawrence Lowlands, the study area corresponds to a 15 km2 corridor between Montreal and Sedimentological study of the Cambro-Ordovician of the St. Lawrence Lowlands City, bordered by the Appalachian Mountains (southeast) and the north shore of the St.
Lawrence River (northwest) (Figure 1). Volduchy. Sedimentological study (Z. KuKAL ) has shown that the sedimen tation basin was bordered in the west by mountain ridges made up mostly ofUpper Cambrian porphyries and porphyrites. Thus, sedimentation took place in an environment of fanglomerates, alluvial.
The Cambro-Ordovician sedimentary basin of the St. Lawrence Lowlands (SLL) in the province of Québec located in eastern Canada is actually under exploration for its low-temperature geothermal.

Kaylor, Donald. The St Lawrence River Basin is the largest in Canada draining the Great Lakes and St Lawrence Lowlands.
A transect was taken across the river at Sorel, Quebec (6, Fig. l) on 5 June, with one sample taken near the north and south banks and one in the centre of the river. The study area is located in the Saint-François River basin (), which covers a surface area of 10, km 2 (), the southern part of which is found in the United States (about 14% of the basin).The St.
Lawrence Lowlands and the Appalachian Mountains are the two major physiographic divisions that characterize this large drainage basin. Purpose of the Study —St. Lawrence County is a large (7, km 2) and sparsely populated, rural, heavily forested county in northern New York (Figure 1a).The southeast half of the county lies within the Adirondack Blue line (Adirondack Park boundary) and is sparsely populated (Figure 1b).Due to its large area and rural nature, much of the region’s population utilizes private groundwater.

According to Rocher et al. () , the St Lawrence lowlands in the Montréal area are represented by a siliciclastic and carbonate platform with a maximum thickness of 1, m.
Ordovician Period, in geologic time, the second period of the Paleozoic Era. It began million years ago and ended million years ago. The interval was a time of intense diversification (an increase in the number of species) of marine animal life in what became known as the Ordovician radiation.

The development of the Cambro-Ordovician siliciclastic veneer that covers much of North Africa and Arabia and spreads thousands of kilometers into the Gondwana hinterland was a fundamental geological process that shaped Earth's surface following the transition from the Precambrian to the Cambrian (Beuf et al.,Burke et al.,Ghienne et al.,Noblet and Lefort, ).
The Ordovician-Silurian Mass Extinction. There are some contests in which it's definitely better to finish in second place instead of first. Mass extinctions would be a good example.
Figure 1 shows the St. Lawrence Lowlands and the Appalachian Plateau, which are the two major physiographic divisions that characterize the Saint-Francois drainage basin. The regional climate is characterized by substantial variations in monthly temperature from [degrees]C in July to [degrees]C in January (Environment Canada a).

Most of these are poorly understood, but one that has been studied occurred in the eastern United States during the early Late Ordovician Epoch. Wilson, Morley E.,Arnprior-Quyon and Maniwaki Areas, Ontario and Quebec, Geological Survey of Canada, Memoirpages.

In St. Lawrence Lowlands, T~ estimated for drill cores from six wells show a strong linear relationship with depth.
The slopes of Tm~x-depth plots provide paleo- geothermal gradients at maximum burial conditions of /km. Extrapolation of these gradients to 15c'C indicate a thickness of km of missing rocks.

(e-mail: [email protected] This course explores the processes of sedimentation and their products in different depositional environments. It covers characteristics and origins of sedimentary rock types; processes that erode, transport and deposit sediments; and post-depositional modification.
Emphasis is on modern depositional environments and how their study can help us better understand ancient depositional. Maximum tidal ranges increase to m entering the St. Lawrence Estuary and range up to m in the St. Lawrence River narrows near Quebec City (Fig.
3A). However, tidal ranges are greatly reduced to m upriver at Trois Rivières because of dissipation of energy at the narrows and the flooding effect in a nearby widening of the river.The pre-Seboomook geologic history in this area can be broadly divided into Cambro-Ordovician and Siluro-Devonian sections (Figure 2).
The first several stops (#B) will concentrate on the older rocks, while the subsequent stops (#3B-6) will examine the younger Siluro-Devonian rocks.
In the Cambro-Ordovician section we concentrate on the.
