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.

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 geology of Massachusetts is the result of a process that began over a billion years ago. Massachusetts currently lies at an edge of a continent, and in the geological past has been the location of many continental collisions and collisions with other microcontinents and volcanic arcs, with their resulting mountain-building events. As a result, the state rock structure is squeezed together. Recently, multiple Ice Ages have shaped the modern geology of the state and have created notable landmarks such as Cape Cod.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
