Chedabucto Fault

Last updated

The Chedabucto Fault is a fault that divides Mainland Nova Scotia from the Minas Basin in the west to Chedabucto Bay in the east into the Avalon zone in the north and the Meguma Zone in the south. The Avalon and Meguma Zones are different because they belonged to different land masses that were widely separated from one another. The Avalon Zone was a part of Laurasia, while the Meguma Zone was a part of Gondwana. It marks the southern margin of the Cobequid Mountains. The Cobequid-Chedabucto Fault Zone is the most prominent geological feature of Nova Scotia.

The Bay of Fundy is a bay between the Canadian provinces of New Brunswick and Nova Scotia, with a small portion touching the US state of Maine. Its extremely high tidal range is the highest in the world. The name is likely a corruption of the French word fendu, meaning 'split'.

Cape Breton Highlands National Park National Park

Cape Breton Highlands National Park is a Canadian national park on northern Cape Breton Island in Nova Scotia. The park was the first national park in the Atlantic provinces of Canada and covers an area of 948 square kilometres (366 sq mi). It is one of 42 in Canada's system of national parks.

In geology, a terrane is a crust fragment formed on a tectonic plate and accreted or "sutured" to crust lying on another plate. The crustal block or fragment preserves its own distinctive geologic history, which is different from that of the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton.

Economy, Nova Scotia

Economy is an unincorporated rural community situated along the north shore of the Minas Basin/Cobequid Bay, at approximately 45°23'N, 63°54'W, in Colchester County, Nova Scotia. In the late 19th century, it was known for its shipbuilding industry.

Upper Economy is a rural area of approximately 50 residents and 5 km2 located along Trunk 2 in western Colchester County, Nova Scotia. It stretches from along the north shoreline of the western end of Cobequid Bay north into the lower slopes of the Cobequid Mountains. Upper Economy is considered locally to be part of the rural community of Economy. It borders Little Bass River to the west.

Shubenacadie River River in Nova Scotia, Canada

The Shubenacadie River is a river in Nova Scotia, Canada. It has a meander length of approximately 72 km from its source at Shubenacadie Grand Lake to its mouth at the historic seaport village of Maitland on Cobequid Bay, site of the building of the William D. Lawrence, the largest wooden ship ever built in Canada. In 2009, the I Backpack Canada blog named the Shubenacadie one of the top five whitewater rivers in Canada. The lower 30 km of the river is tidal and the river experiences a tidal bore twice daily, with some bores reaching up to 3 m in height at certain points along the river. Local tourism operators offer adventure seekers a chance to ride with the bore on high-horse power Zodiac Hurricanes. Tidal Bore Rafting was invented at the Tidal Bore Rafting Resort by H. Knoll. It is also a popular surfing spot for experienced Sea Kayakers.

Cobequid fault

The Cobequid Fault is a fault that is the extension of the Chedabucto Fault. This fault runs from Truro to Cape Chignecto south of the Cobequid Hills. Both the Cobequid fault and the Chedabucto Fault form the Minas Fault zone splitting Nova Scotia into the Avalon Zone and the Meguma Zone. Movement on the Cobequid Fault started before 400 million years ago and end around 40 million years ago. Between that time around 350 million years violent volcanic eruptions at Spicers Cove north Cape Chignecto Provincial Park and 50 million years after grey sandstone rich in fossil plants were deposited. At Five Islands Provincial Park there are red rocks formed by the large accumulation of mud, sand and gravel around 210 million years ago.

Cobequid

The old name Cobequid was derived from the Mi'kmaq word "Wagobagitk" meaning "the bay runs far up", in reference to the area surrounding the easternmost inlet of the Minas Basin, a body of water called Cobequid Bay.

Geology of Massachusetts

The geology of Massachusetts includes numerous units of volcanic, intrusive igneous, metamorphic and sedimentary rocks formed within the last 1.2 billion years. The oldest formations are gneiss rocks in the Berkshires, which were metamorphosed from older rocks during the Proterozoic Grenville orogeny as the proto-North American continent Laurentia collided against proto-South America. Throughout the Paleozoic, overlapping the rapid diversification of multi-cellular life, a series of six island arcs collided with the Laurentian continental margin. Also termed continental terranes, these sections of continental rock typically formed offshore or onshore of the proto-African continent Gondwana and in many cases had experienced volcanic events and faulting before joining the Laurentian continent. These sequential collisions metamorphosed new rocks from sediments, created uplands and faults and resulted in widespread volcanic activity. Simultaneously, the collisions raised the Appalachian Mountains to the height of the current day Himalayas.
