Why kimberlite might be found in diamonds?
Kimberlite is the natural structure within which diamonds are found (kimberlite "pipe"). A Kimberlite pipe is the normal underground site(s) of a diamond bearing geologic formation.Another AnswerKimberlite is a mineral, called a trace mineral, because in one out of 200 cases, when kimberlite is found, diamonds are also found. Why? Because the geological processes required to form diamonds also forms kimberlite, which is a 'potassic volcanic rock' according to Wikipedia.
How can diamonds form at river beds?
Diamonds don't 'form' in river beds or in the sea bed where some are found. Diamonds are propelled into river beds and to the sea by water that flows over the kimberlite pipe where the diamonds are formed.Diamonds found in water are generally referred to as alluvial stones, meaning deposited in the water over a long period.
What has diamonds in it?
There are indicator minerals that diamonds may be nearby, such as kimberlite. Some precision tools have been enhanced with the addition of diamond material to the tip. Jewelery may have diamonds included in its design.
How do diamonds arrive in streams?
Some diamonds are found in rivers and in the mouths of rivers as they flow into the ocean. Water flowing over the tops of the volcanic pipes -- which push the stones to the earth's surface -- deposits the diamonds where they can be found in flowing water.These diamonds are called alluvial diamonds.
Can diamonds be found in an iron ore mine?
Diamonds are typically not found in iron ore mines. Diamonds are formed deep within the Earth's mantle, while iron ore deposits are more commonly formed in different geological settings, such as sedimentary rocks or banded iron formations. Diamonds are usually associated with kimberlite or lamproite pipes, which are different from the environments where iron ore is found.
Which layer of earth forms diamonds?
The vast majority of diamonds form within the Earth's lithospheric mantle at depths of around 150 to 190 km. Volcanic activity brings them to the surface in the form of volcanic pipes known as kimberlite or lamproite pipes.
Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
What is a craton and what is a kimberlite pipe and how are they linked to the discovery of the diamond?
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
What diamonds are in volcanoes?
Diamonds found in volcanoes are typically formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought to the surface during volcanic eruptions through volcanic pipes called kimberlite pipes or lamproite pipes. These diamonds are known as "kimberlite diamonds" or "volcanic diamonds".
Why are diamonds found in kimberlite rock?
Apparently kimberlite pipes -- that can contain diamonds -- are volcanic formations that begin deep within the earth's mantle. Because diamonds and kimberlite -- and other semi-precious gems -- are formed in similar locations, some kimberlite rock contains diamonds. You can read more, below.
In what geologic settings do diamonds occur?
Diamonds typically occur in two main geologic settings. The first is in kimberlite pipes, which are vertical, carrot-shaped volcanic pipes that bring diamonds from the mantle to the surface. The second setting is in alluvial deposits, where diamonds are eroded from the primary source and transported by rivers to be deposited in sediment.
Where can you find Raw diamonds?
In 'kimberlite pipes' which are volcanic vents deep underground in South Africa, Brazil, Canada, Australia and India. Also in river sediments the flow over these pipes, and kimberlite pipes in other parts of Africa.
What geologic feature seems to be a common location for finding diamonds?
Kimberlite pipes are a common geologic feature where diamonds are found. These cylindrical volcanic rock formations bring diamonds to the Earth's surface from deep within the mantle. Diamonds are typically formed under high pressure and temperature conditions, and kimberlite pipes are one of the few mechanisms for bringing them to the surface.
Where can you find diamonds other than a kimberlite pipe?
Natural diamonds from the Earth originate in kimberlite pipes, and can be swept away by water or glaciers. This means that some diamonds are found in river beds and at the mouths of rivers as they empty into salt water.
Were on earth is diamonds normally found?
Diamonds are normally found in kimberlite pipes, which are ancient volcanic rock formations found in specific regions of the world such as Africa, Russia, Canada, and Australia. These kimberlite pipes bring diamonds from the Earth's mantle to the surface through volcanic eruptions.
Are most diamonds mined directly from Kimberlite?
Kimberlite is an indicator mineral, formed deep within the earth's mantle where diamonds are also formed. Often, they are found together, but not always. Kimberlite is not diamond: they are different minerals.
Are diamonds formed in veins?
No. Diamonds are erupted to the surface of the earth by volcanic pipes, together with other matter, including kimberlite. There is no pattern in the eruption that determines the existence of diamonds.
