What is Ol Doinyo Lengai?
Ol Doinyo Lengai is a volcano in Tanzania notable for the fact that it erupts unique carbonatite lava.
What temperature is molten rock?
It varies. Basaltic magma ranges between 1,800 and 2,200 degrees Fahrenheit while rhyolitic magma can be as "cool" as 1,200 degrees. Rare carbonatite magma ranges from 950 to 1,100 degrees.
What is the temperature of lava from a composite volcano?
The temperature varies widely, ranging from high temperatures of 1,800 to 2,200 degrees Fahrenheit for basaltic lava to as low as 1200 degrees of Rhyolitic lava. Ol Doinyo Lengai, a composite volcano in Africa, erupts unique carbonatite lava with temperatures between 950 and 1100 degrees.
What kind of magma forms limestone?
Limestone is not formed from magma; it is a common sedimentary rock. However it may be worth noting that there is a rare form of igneous rock known as Carbonatite which is formed predominately from carbonate minerals and may be confused with Marble, however it is never described as Limestone. Please see the related link.
What type of lava do strato volcanoes have?
The textbook answer would be andesite. In reality stratovolcanoes are highly variable and have been known to erupt all of the types of lava observed on modern earth from basalt to rhyolite, sometimes from the same volcano. One stratovolcano even erupts unique carbonatite lava.
What igneous rock forms into marble?
carbonatite
What rocks do Ol Doniyao Lengai erupt?
Ol Doinyo Lengai is a unique volcano in that it erupts carbonatite lava, which cools to form carbonatite. It is unusual in that all other currently active volcanoes erupt silicate based material while this is carbonate based.
What rocks begin with the letter S?
Sovite is a coarse grained carbonatite rock. Shale is a sedimentary rock.
What is an igneous rock composed of calcium carbonate?
Carbonatite is an igneous rock composed of more than 50% Calcium Carbonate.
What is Ol Doinyo Lengai?
Ol Doinyo Lengai is a volcano in Tanzania notable for the fact that it erupts unique carbonatite lava.
How do people use carbonatite Not Land or anything else?
If you are asking about carbonatite, it is a mineral form of rock that contains valuable metals, including copper, uranium, thorium, etc.If you meant Carbonite (different spelling) that is an on-line data backup service. People store computer information on their site. If your computer crashes, you can recover your data from their site.
What temperature is molten rock?
It varies. Basaltic magma ranges between 1,800 and 2,200 degrees Fahrenheit while rhyolitic magma can be as "cool" as 1,200 degrees. Rare carbonatite magma ranges from 950 to 1,100 degrees.
What has the author James E Mungall written?
James E. Mungall has written: 'Geochemistry of carbonatite and alkali pyroxenite, Bancroft terrane, Grenville province, Ontario' -- subject(s): Geochemistry, Pyroxenite, Rocks, Sedimentary, Sedimentary Rocks
Is calcite a sedimentary?
Calcite is a mineral, not a rock. It can occur as part of rocks in any category. For instance, the sedimentary rock chalk consists almost entirely of calcite, the metamorphic rock marble consists mostly of calcite, and the igneous rock carbonatite consists mostly of calcite.
How does limestone change into basalt?
It doesn't. They have different chemical compositions. Limestone is CaCO3. Basalt is mainly SiO4 and Fe. There is however an igneous rock composed predominantly of carbonate minerals known as carbonatite. This tends to form at zones of continental rifting. It isn't basalt however!
What has the author D A Singer written?
D. A Singer has written: 'Preliminary version of FINDER, a Pascal program for locating mineral deposits with spatial information' -- subject(s): Mines and mineral resources, Computer programs 'Revised grade and tonnage model of carbonatite deposits' -- subject(s): Carbonatites
What kind of lava does a lava volcano have?
The textbook answer would be granitic or rhyolitic lava. In reality composite volcanoes are highly variable, erupting the full range from basaltic to rhyolitic (granitic) materal and everything in between includin andesite and dacite. One composite volcano in Africa erupts unique carbonatite lava.
