Old Doinyo Lengai fountain of liquid magma, height of 2960 meters (9711 feet), is a remarkable and very captivating well of lava that pinnacles over the East African Rift Valley in Northern Tanzania, only south of Lake Natron. The main fountain of liquid magma on the planet in some cases ejects natrocarbonatite magma, profoundly liquid magma that contains practically no silicon.

Natrocarbonatite magma is likewise a lot cooler than different magmas, being around 950 degrees F (510 degrees C) contrasted with temperatures north of 2000 degrees F (~1100 degrees C) for basaltic magmas. Natrocarbonatite is the most liquid magma on the planet. Magma with a low gas content can stream like a whitewater stream, and really has a consistency close to that of water.

Natrocarbonatite magma shines orange around evening time however isn’t close to as brilliant as silicon-based magmas since it isn’t as sweltering. During the day it isn’t radiant; most streams seem to be exceptionally liquid dark oil, or earthy colored froth, contingent upon the gas content. Before, a few guests to the cavity accepted they were seeing mudflows. Most recently hardened magma is dark and contains gems that radiance brilliantly in the sun.

There are additionally in some cases little streams known as “crush ups” that are light dim when they stream and solidify. Contact with dampness quickly turns natrocarbonatite magma white on account of substance responses that happen when the magma assimilates water.

At last, the water retention process transforms magma streams into a delicate earthy colored powder. During dry climate the brightening of streams occurs over a time of a couple of days to a long time, contingent upon the thickness of the stream. In stormy climate, the magma surface becomes white right away.

In pieces of the hole that have been idle for a long time, the ground is light brown/white thus delicate that one sinks into it while strolling.

Old Doinyo Lengai additionally has periods of touchy movement during which the structure of the magma might contain substantially more silicate material, diminishing its consistency. In this kind of emission, there is no liquid magma and movement appears as debris emissions joined by the launch of squares and bombs.

In any case, the underlying periods of a dangerous ejection might areas of strength for incorporate wellsprings. The two latest touchy emissions happened during 1966-1967 and 2007-2008.

Since the mid 1980s, magma streams, and to a lot lesser degree, unstable emissions, have been seen by numerous eyewitnesses of Ol Doinyo Lengai. Natrocarbonatite magma ejections are generally focused in at least one little cones that have been shaped on the hole floor by past emissions of magma.

These emissions have ordinarily appeared as open magma pools or lakes that might be spilling over, magma streams giving from openings or breaks inside or close to the foundation of the cones, or magma sprinkles or wellsprings from the culmination vents of the cones.

The action isn’t surely known however is believed to be a component of the pipes of the pit, the level of the magma inside the pipes, and the gas content of the magma. Nobody realizes what makes the magma stream out at a specific time or how the different vents in the pit are interconnected.

Mineralogists might want to comprehend how the magma advances on a deeper level and why it has its uncommon substance organization, yet that likewise is obscure, despite the fact that there are a few hypotheses. At last, nobody knows why the example of regular little magma streams gave way to dangerous action toward the finish of August 2007 and how that might have been connected with tremors in the district during the past two months.
