What is Baikal Rift Zone?

What is Baikal Rift Zone?

The Baikal Rift Zone is a series of continental rifts centered beneath Lake Baikal in southeastern Russia. A series of basins form along the zone for more than 2,000 kilometres (1,200 mi), creating a rift valley. The rifts form between the Eurasian Plate to the west and the Amur Plate to the east.

Where is Baikal Rift Zone?

Siberia
The Baikal rift zone is composed of a branched chain of Late Cenozoic half-grabens extending over a distance of about 1500km in Siberia [1–3] (Fig. 1). It is situated at the boundary of the Siberian platform (craton) to the north-west and the Mongolian fold belt to the south-east.

What type of boundary is the Baikal Rift Zone?

divergent plate boundary
The Baikal Rift Valley is formed by a divergent plate boundary, where the Amur plate is slowly tearing itself away from the Eurasian plate, and has been doing so for about 25 million years. The Amur plate is moving eastward at a rate of about 4 to 5 millimeters (. 16 to . 2 inch) a year.

When did the Baikal Rift Zone form?

The Baikal rift basins began to form in the Oligocene (about 30–35Ma) and they are still developing. Magmatism related to the development of the rift zone is relatively small in volume.

Is Lake Baikal a rift lake?

Due to their high sedimentation rates, large rift lakes like Lake Baikal have great potential for providing high-resolution information about both tectonic and climatic change. Significantly, sedimentary deposits of continental rifts are also associated with many of the Earth’s hydrocarbon and mineral deposits.

How large is Lake Baikal?

What plate boundary is Lake Baikal on?

Baikal Rift Zone
Lake Baikal is situated in Russia, directly on the plate boundary between the Eurasian and Amurian plates, known as the Baikal Rift Zone. It is about 34,000km^2, with a maximum depth of 1642m (Intas Project 99-1669, 2002), resulting in a volume greater than that of all the great lakes combined.

Is transform boundary?

A transform fault or transform boundary, sometimes called a strike-slip boundary, is a fault along a plate boundary where the motion is predominantly horizontal. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern.

Is East African Rift a mid ocean ridge?

If the process continues long enough and the continental crust is effectively separated, the continental rift graben turns into a normal mid-oceanic ridge. The most prominent example of a continental rift is the East-African Rift Valley and its continuations into the Red Sea and the Gulf of Aden.

Is Baikal Zen real?

Rare ‘Baikal Zen’ Phenomenon Has Rocks Balancing on Pedestals of Ice on Lake Baikal. Lake Baikal in Siberia produces an incredible phenomenon when the weather turns bitterly cold. The wonder is known as Baikal Zen, in reference to the stacking of stones found in Japanese gardens.

Can you drink water from Lake Baikal?

Baikal is a fresh water lake, so it is possible to take the water from the lake directly, boil it, and then drink it.

Where are the rifts in Lake Baikal located?

Map of the Lake Baikal Rift Zone from the USGS factsheet. The Baikal Rift Zone is a series of continental rifts centered beneath Lake Baikal in southeastern Russia. Current strain in the rifts tends to be extending with some shear movement.

What kind of water does Lake Baikal have?

Baikal is rich in oxygen, even in deep sections, which separates it from distinctly stratified bodies of water such as Lake Tanganyika and the Black Sea. In Lake Baikal, the water temperature varies significantly depending on location, depth, and time of the year.

How long does it take for Lake Baikal to freeze?

Water characteristics. In Lake Baikal, the water temperature varies significantly depending on location, depth, and time of the year. During the winter and spring, the surface freezes for 4–5 months; from early January to May–June (latest in the north), the entire lake surface is covered in ice.

Where are the rifts in the Eurasian Plate?

A series of basins form along the zone for more than 2,000 kilometres (1,200 mi), creating a rift valley. The rifts form between the Eurasian Plate to the west and the Amur Plate to the east. To the northwest of the rifts is the Siberian Craton, on the Eurasian Plate.
