Where is Charlie-Gibbs Fracture Zone?

The Charlie-Gibbs Fracture Zone (CGFZ) is the largest geological fault in the northern Mid-Atlantic Ridge between Iceland and the Azores.

What type of plate boundary is the Charlie-Gibbs Fracture Zone?

INTERESTING FACT: The Charlie-Gibbs Fracture Zone is a system of two parallel fracture zones. It is the most prominent interruption of the Mid-Atlantic Ridge between the Azores and Iceland. It can be traced over more than 2,000 kilometers, all the way from north-east of Newfoundland to south-west of Ireland.

What is the Atlantis fracture zone?

The Atlantis Fracture Zone (30° N) is one of the smallest transform faults along the Mid-Atlantic Ridge with a spatial offset of 70 km and an age offset of ~ 6 Ma. The morphology of the Atlantis Fracture Zone is typical of that of slow-slipping transforms. The transform valley is 15–20 km wide and 2–4 km deep.

Where is the eltanin fracture zone?

Pacific-Antarctic Ridge
The Eltanin Fault System (Eltanin Fracture Zone) is a series of six or seven dextral transform faults that offset the Pacific-Antarctic Ridge, a spreading zone between the Pacific Plate and the Antarctic Plate.

Where are fracture zones located?

mid-ocean ridges
Fracture zones are common features in the geology of oceanic basins. Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them.

What can be found at fracture zones?

Geologic importance However, by observing the fracture zones, one can determine both the direction and rate of past plate motion. This is found by observing the patterns of magnetic striping on the ocean floor (a result of the reversals of Earth’s magnetic field over time).

How many fracture zones are there?

There are about 300 fracture zones, with an average north-south separation of 55 kilometres (34 mi): two for each degree of latitude. Physically it makes sense to group Atlantic fracture zones into three categories: Small offset: length of transform fault less than 30 kilometres (19 mi)

What is a fracture zone in geography?

a long, narrow rift on the ocean floor, separating areas of differing depth: where such a zone crosses a mid-ocean ridge, it displaces the ridge by faulting. GOOSES. GEESES.

How are fracture zones like eltanin created?

How are fracture zones like the Eltanin created? They are the scars on the seafloor basalt that are created by offsets in the mid-ocean ridge.

How do fracture zones form?

Fracture zones are the scars left in plate interiors by the action of transform faults that offset mid-ocean ridge segments. This transform faulting occurs at the ends of spreading segments where melt supply may be either reduced or enhanced, leading to crustal thickness contrasts across transform faults.

What is an example of fracture zone?

Romanche Fracture Zone Also known as the Romanche Trench, this fracture zone separates the North Atlantic and South Atlantic Oceans. The trench reaches 7,758 m deep, is 300 km long, and has a width of 19 km. The fracture zone offsets the Mid-Atlantic Ridge by more than 640 km.

What does fracture zone mean?

fracture zone in American English noun. Geology. a long, narrow rift on the ocean floor, separating areas of differing depth: where such a zone crosses a mid-ocean ridge, it displaces the ridge by faulting.

What is the Charlie Gibbs Fracture Zone?

Where is the Charlie Gibbs transform fault?

Charlie-Gibbs transform fault. Charlie-Gibbs Fracture Zone is a system of two parallel fracture zones. It is the most prominent interruption of the Mid-Atlantic Ridge between the Azores and Iceland. It can be traced over more than 2000 kilometers, all the way from north-east of Newfoundland to south-west of Ireland.

Where is the Charlie-Gibbs Ridge?

BATHYMETRY AND GEOMORPHOLOGY The Charlie-Gibbs Ridge lies in the northeast Atlantic between the intersection of the Maury Seachannel with the Charlie-Gibbs F.Z. and the Edoras Bank on the Rockall Plateau (Fig. 1), at 520’N and between 250’W and 270’W. This is about 90 nautical miles (n.m.) northeast of the Mid-Atlantic Ridge.

What is the Charlie-Gibbs marine protected area?

The Charlie-Gibbs Marine Protected Area is a conservation area in the Charlie-Gibbs fracture zone in North Atlantic international waters. ^ Lilwall, R. C.; Kirk, R. E. (1985).
