What two material types of volcanic material make up composite volcanoes?
It is highly variable. Magmas ranging all the way from basaltic to rhyolitic occur in stratovolcanoes. Andesitic magma is the most common type. One stratovolcano erupts carbonatite lava, a carbonate-based melt that is unlikely anything that erupts from any other currently active volcano.
What is Ol Doinyo Lengai?
Ol Doinyo Lengai is an active volcano located in Tanzania. It is known for its unique lava composition that is rich in sodium carbonate minerals, giving it a dark color and making it cooler in temperature compared to other lavas. The Maasai people consider it a sacred mountain.
What plate boundary is ol doing lengai on?
Ol Doinyo Lengai is located in East Africa, specifically in the East African Rift, which is a divergent plate boundary. This region is characterized by the tectonic plates moving apart, leading to the formation of rift valleys and volcanic activity. Ol Doinyo Lengai is unique because it is the only active volcano that erupts carbonatite lava, which is associated with the rifting process.
What temperature is molten rock?
Molten rock, or magma, typically has a temperature ranging from 1300 to 2400 degrees Fahrenheit (700 to 1300 degrees Celsius). The exact temperature can vary depending on the composition of the rock and where it is located within the Earth's crust.
What kind of magma forms limestone?
Limestone is not formed from magma. Limestone is primarily formed from the accumulation of marine organisms such as shells and coral fragments. It is a sedimentary rock, not an igneous rock formed from magma.
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.
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 is an igneous rock composed of calcium carbonate?
An igneous rock composed of calcium carbonate is called carbonatite. It typically forms from the melting of carbonate-rich minerals in the Earth's mantle, resulting in a rock dominated by minerals such as calcite, dolomite, and siderite. Carbonatites are rare and are known for their unusual mineral compositions.
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.
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.
